What’s the difference between inground pool pumps and above ground pool pumps?

what's the difference between inground pool pumps and above ground pool pumps? Can an inground pool pump be used for an above ground pool?

Written by Catherine Zhou on June 14 2024

Recently, one of our distributor said that the sand filters he purchased from us has some problems: valve leaks, tank leaks.

I’m surprised about her feedback, as we’ve never heard about this from our other distributors.

After discussing about this problem with our engineer team, we found that this distributor has changed the pumps in the sand filter combo. The original pump included in the sand filter was an above ground pool pump, however, he prefer the appearance of our inground pool pump(max power pro series), so he asked us to replace the pump by the inground pool pump(max power pro series) of the same horse power. 

He purchased 12″, 16″, 19″ and 24″ sand filter & pump combos from us, the pumps in the 12″ and 16″ combos are not changed which the pumps in the 19″ and 24″ combos were replaced by the inground pool pumps. All the sand filter issue he reported were from the 19″ and 24″ sand filters.

So, one of our engineers put forwarder a bold hypothesis: Will the problem lay on the replacement of the pump?

Based on this hypothesis, we conducted an experiment on a transparent sand filter with an inground pool pump and an above ground pool pump so as to observe and compare the movement of water flow and sand in the tank.

After starting the pump, we saw a lot of sand were slammed into the top valve head when running the inground pool pump while the water flow was very gentle in the tank when running the above ground pool pump.

We also noticed that the pressure in the tank had almost reached 300Kpa which is the limit valve of our sand filter when running the inground pool pump, but the pressure was below 250Kpa when running the above ground pool pump.

After running the inground pool pump for some days, we stopped the pump and took off the top valve, we found that their were a lot of sand  stuck to the rubber/pad/O-ring of the top valve which will wear the rubber/pad/O-ring and other seal parts after some period and cause leakage then.

Consider the high pressure of the tank, operating at 300Kpa which is the max working pressure of the tank in the long run will easy to damage the tank when the sand is full of debris which will cause even higher pressure to the tank.

We told the distributor about our experiment results, he was surprised and suggested to use inground pool pump(max power pro) of smaller horse power. Ha, what a persistent man who loves our max power pro series inground pool pump very much!

Then we conducted another experiment, to degrade the pump horse power for 19″ and 24″ sand filters. For example, he sold 0.75HP inground pool pump with the 19″ sand filter previously, now we test 0.5HP inground pool pump with the sand filter to see how it works. The same as on 24″ sand filters, we degrade the 1HP inground pool pump to 0.75HP one.

The result shows better than before, sand flows more gently and pressure of the tank reduced to around 250Kpa, which is almost the same as it with an above ground pool pump.

So finally he purchased 0.5HP inground pool pump with the 19″ sand filter and 0.75HP inground pool pump with the 24″ sand filter from us. 

After then, not a complaint has been mentioned, he is very satisfied with the new combos!

This year, his pool business goes on well and purchased double qty than last year!

This is an interesting case, we didn’t improve anything, all the issues were fixed only by degrading the horse power of the inground pool pump, so now we have learnt from the case:

  1. Do not easily replace any part of the combo so as to avoid unnecessary troubles.
  2. If you want to change any part of the suit,  rigorous evaluations should be done before doing so.
  3. An above ground pool pump can be replaced by an inground pool pump, but there are many factors to consider, the main factor is the water flow and the pressure.

Let me tell you why based on the difference between an above ground pool pump and an inground pool pump.

The primary differences between inground pool pumps and above ground pool pumps relate to their design, performance, and installation requirements. Here are the key distinctions:

Design and Build

  1. Pressure Handling:

    • Inground Pool Pumps: Designed to handle higher pressures because inground pools have more resistance due to longer plumbing lines and additional features such as waterfalls and spa jets.
    • Above Ground Pool Pumps: Handle lower pressures as above ground pools typically have shorter plumbing lines and fewer additional features.
  2. Durability:

    • Inground Pool Pumps: Usually built with more durable materials to withstand the constant pressure and longer running times.
    • Above Ground Pool Pumps: May use lighter materials suitable for the less demanding operational environment.

Installation and Operation

  1. Installation:

    • Inground Pool Pumps: Often require professional installation due to the complexity of inground pool plumbing systems and electrical requirements.
    • Above Ground Pool Pumps: Generally easier to install and can often be set up by the pool owner without professional assistance.
  2. Priming:

    • Inground Pool Pumps: Typically self-priming, meaning they can automatically remove air from the system to start pumping water effectively, which is necessary for the longer and more complex plumbing systems of inground pools.
    • Above Ground Pool Pumps: Usually not self-priming and must be installed below the water level of the pool to ensure they can start pumping water without manual priming.

Performance

  1. Flow Rate and Horsepower:

    • Inground Pool Pumps: Generally have higher horsepower and flow rates to move larger volumes of water through more extensive filtration systems.
    • Above Ground Pool Pumps: Typically have lower horsepower and flow rates appropriate for the smaller volumes of water and simpler filtration systems in above ground pools.
  2. Energy Efficiency:

    • Inground Pool Pumps: Often come with variable speed options to improve energy efficiency and provide more precise control over water circulation.
    • Above Ground Pool Pumps: Usually single-speed or two-speed, reflecting the simpler needs and lower operational demands.

Cost

  1. Inground Pool Pumps: Tend to be more expensive due to their robust construction, higher performance, and advanced features.
  2. Above Ground Pool Pumps: Generally less expensive, reflecting their simpler design and lower performance requirements.

In summary, inground pool pumps are built to handle higher pressures, have more complex installation requirements, and offer higher performance and durability. Above ground pool pumps are simpler, easier to install, and suitable for the lower demands of above ground pools.

Let’s return to the previous question: can an inground pool pump be used in an above ground pool?

The answer is

Yes, an inground pool pump can be used in an above ground pool, but several factors need to be considered:

Suitability

  1. Power and Flow Rate: Inground pool pumps typically have higher power and flow rates. If used in an above ground pool, this may cause the water to flow too quickly, potentially leading to ineffective filtration or damage to the pool’s plumbing and filtration system.

  2. Installation Position: Inground pool pumps are usually self-priming and can be installed above the water level. Most above ground pool pumps need to be installed below the water level to ensure proper operation. You need to ensure that the pump’s installation position and design are compatible with the requirements of an above ground pool.

Energy Efficiency

Inground pool pumps are designed for larger loads and long-term high-efficiency operation. If used in an above ground pool, they may consume more electricity, leading to lower energy efficiency.

Safety and Durability

Above ground pool systems are typically designed to handle lower pressures. Using a high-pressure inground pool pump may increase wear and tear on the system, reducing the lifespan of the above ground pool equipment.

Cost

Inground pool pumps are generally more expensive. Using them for an above ground pool may be resource-intensive and not cost-effective, especially for smaller pools.

Adjustability

Some inground pool pumps have adjustable speed features, allowing you to reduce the flow rate and pressure, making them more suitable for above ground pools. If you decide to use an inground pool pump, choosing a model with this feature might be more appropriate.

Conclusion

While it is technically possible, you need to carefully consider the factors mentioned above. If you must use an inground pool pump, it is advisable to consult a professional to ensure system compatibility and safety. Additionally, it might be more suitable to choose a pump specifically designed for above ground pools to avoid potential issues.

Beyond Chlorine: Will Chlorine Tablet and Salt Chlorinator be Replaced by Copper-Silver Ionizer?

Beyond Chlorine: Will Chlorine Tablet and Salt Chlorinator be Replaced by The Copper-Silver Ionization?

Written by Catherine Zhou on May 31 2024

Last Month, I went to the Asia Pool & Spa Expo in Guangzhou, it was double size than that in 2023, I saw many new exhibitors, but not so many new products, most products were conventional.

However, I did notice that some exhibitors have copper-silver ionizers on their platforms, which though has already exists in pool industry but not quite common in Chinese pool industry due to its expensive cost and high technology or maybe other reasons waiting to be furtherly discussed.

I read a brochure of one of the copper-silver ionizer suppliers, and was attracted by the advantages of the copper-silver ionzier compared to the traditional chlorine based disinfection method. It says the ionizer will do no harm to human body while chlorine will cause some trouble to our health. Honestly speaking, my daughter struggles with a severe chlorine allergy. Every time she swims, her skin peels and, in severe cases, she can’t even play the piano or violin due to the painful hands. Because of this, she hasn’t been able to swim in a long time, even though she loves being in the water.

So I decided to look into this kinds of product deeply to see if they can replace the chlorine based disinfection method of pool water. Maybe this is an opportunity to disrupt the industry and benefit those allergic to chlorine, who knows?

Here’s what I have found so far, I would like to share it to you–

Introduction

Background on Swimming Pool Disinfection

Maintaining hygiene in swimming pools is critical to ensuring the safety and health of swimmers. Pool water can harbor various pathogens, including bacteria, viruses, and protozoa, which can cause a range of illnesses, from skin infections to more serious conditions such as respiratory and gastrointestinal diseases. As such, effective disinfection methods are essential.

Traditionally, chlorine-based methods have been the most commonly used for pool disinfection. Chlorine tablets and salt chlorinators are popular choices due to their proven efficacy and relatively low cost. However, chlorine has its drawbacks, including the production of harmful byproducts and potential health risks associated with its use.

Introduction to Copper-Silver Ionization

Copper-silver ionization is an alternative disinfection method that has gained attention in recent years. This technology uses electrolysis to release copper and silver ions into the pool water, which then work to kill microorganisms. The bactericidal properties of copper and the virucidal properties of silver make this method a promising option for maintaining pool hygiene without the use of chlorine.

This paper aims to explore the potential of copper-silver ionization to replace traditional chlorine-based disinfection methods. By comparing the mechanisms, effectiveness, safety, environmental impact, and economic considerations of both methods, this study seeks to provide a comprehensive analysis of the viability of copper-silver ionization as a primary disinfection strategy for swimming pools.

Comparison of Disinfection Methods

Mechanisms of Action

Chlorine: Chlorine works by chemically oxidizing organic matter and pathogens in the water, leading to rapid disinfection. When chlorine is added to water, it forms hypochlorous acid, which is highly effective at killing bacteria, viruses, and algae.

Salt Chlorination: Salt chlorinators produce chlorine through the process of electrolysis. Salt (sodium chloride) is added to the pool water, and the chlorinator converts the salt into chlorine gas, which then dissolves in the water to form hypochlorous acid.

Copper-Silver Ionization: Copper-silver ionization systems use an electric current to release copper and silver ions from electrodes into the pool water. Copper ions disrupt the cell walls of bacteria and algae, while silver ions interfere with the DNA and protein structures of viruses and bacteria, effectively killing them.

Effectiveness Against Pathogens

The effectiveness of each disinfection method varies based on the type of pathogen and the conditions in the pool water. Chlorine is highly effective against a broad spectrum of pathogens, including bacteria, viruses, and protozoa. Its rapid action makes it ideal for quickly disinfecting pool water and maintaining a residual level of protection.

Salt chlorination offers similar benefits to traditional chlorine but with the added advantage of continuous chlorine production, ensuring consistent disinfection levels. This method is particularly effective in high-use pools where maintaining chlorine levels can be challenging.

Copper-silver ionization has been shown to be effective against a range of pathogens, including bacteria, viruses, and algae. However, its disinfection speed is slower compared to chlorine, and it may require longer contact times to achieve the same level of pathogen reduction.

Disinfection Speed and Residual Effect

Chlorine provides immediate disinfection upon contact with pathogens and maintains a residual effect, continuously disinfecting the water as it circulates. This residual effect is crucial for preventing the growth of microorganisms between treatments.

Salt chlorination also offers a continuous disinfection process, as the chlorinator generates chlorine as long as the system is operational. This ensures a constant level of disinfection and reduces the need for frequent manual chlorine additions.

Copper-silver ionization, while effective, does not provide the same immediate disinfection as chlorine. The ions take longer to kill pathogens, and maintaining the correct concentration of copper and silver ions is essential for ongoing disinfection. Regular monitoring and adjustment are necessary to ensure optimal performance.

Safety and Health Considerations

Chemical Byproducts and Health Risks

Chlorine Byproducts: One of the primary concerns with chlorine-based disinfection is the formation of disinfection byproducts (DBPs), such as chloramines and trihalomethanes (THMs). These byproducts are formed when chlorine reacts with organic matter in the water. Chloramines can cause respiratory issues and skin irritation, while THMs are associated with potential long-term health risks, including cancer.

Copper and Silver Toxicity: Copper and silver ions, while effective at killing pathogens, must be carefully regulated to avoid potential health risks. Excessive copper levels can cause staining of pool surfaces and hair, as well as gastrointestinal issues if ingested. Silver, although generally considered safe at low concentrations, can accumulate in the body over time and potentially cause argyria, a condition characterized by a bluish-gray discoloration of the skin.

Regulatory Standards and Guidelines

Regulatory standards for pool disinfection vary by region, but most guidelines set limits on the allowable concentrations of disinfectants and their byproducts. For chlorine, these limits are well established, and pool operators are required to regularly test and adjust chlorine levels to comply with health and safety regulations.

For copper-silver ionization, regulatory standards are less widely established, and guidelines for safe ion concentrations are still being developed. Pool operators using this method must adhere to manufacturer recommendations and conduct regular water testing to ensure compliance with safety standards.

Environmental Impact

Environmental Concerns with Chlorine

The production, transportation, and disposal of chlorine pose several environmental concerns. Chlorine is a hazardous chemical, and its production generates toxic byproducts. Additionally, when chlorine is discharged into the environment, it can persist and negatively impact aquatic ecosystems.

Environmental Benefits of Copper-Silver Ionization

Copper-silver ionization systems have a lower environmental impact compared to chlorine. These systems do not produce harmful byproducts, and the ions used for disinfection are less toxic to aquatic life at the concentrations used in pool water. However, careful management is necessary to prevent the accumulation of copper and silver in the environment.

Economic Considerations

Cost Analysis

Initial Setup Costs: Copper-silver ionization systems typically have higher initial setup costs compared to chlorine-based systems. The cost includes the ionization unit, installation, and initial calibration.

Operational and Maintenance Costs: Over time, the operational and maintenance costs of copper-silver ionization can be lower than those of chlorine-based systems. Copper and silver electrodes need periodic replacement, but the overall maintenance requirements are generally less frequent. Chlorine systems, on the other hand, require regular chemical purchases and more frequent monitoring and adjustments.

Long-Term Financial Implications

In the long term, copper-silver ionization systems can be cost-effective due to lower operational costs and reduced need for frequent chemical additions. However, the initial investment may be a barrier for some pool operators. A thorough cost-benefit analysis is essential to determine the financial viability of switching to copper-silver ionization.

Case Studies and Practical Applications

Successful Implementations of Copper-Silver Ionization

Public Pools and Recreation Centers: Various public pools and recreation centers have successfully implemented copper-silver ionization systems. For example, some municipalities have adopted this technology to reduce the use of chlorine and its associated byproducts, improving air and water quality for swimmers and staff. These case studies often report positive feedback regarding the reduced chemical smell and fewer instances of skin and eye irritation.

Hotels and Resorts: High-end hotels and resorts have adopted copper-silver ionization to enhance guest experiences. By providing a more pleasant swimming environment with fewer chemical odors and irritants, these establishments improve customer satisfaction. Case studies from these settings highlight the balance between maintaining high water quality and reducing chemical use.

Schools and Universities: Educational institutions with swimming facilities have also explored copper-silver ionization. These implementations focus on the safety and health benefits for students, along with cost savings over time. Reports from schools and universities often emphasize the reduced maintenance and operational costs compared to traditional chlorine systems.

Challenges and Limitations Encountered

Technical Challenges: Despite its advantages, copper-silver ionization can face technical challenges such as maintaining optimal ion concentrations and ensuring uniform ion distribution throughout the pool. Variations in water chemistry, temperature, and flow rates can affect system performance.

User Acceptance and Perceptions: One of the main challenges is user acceptance. Pool operators and users accustomed to chlorine may be hesitant to switch to a new system. Education and awareness campaigns are essential to address misconceptions and highlight the benefits of copper-silver ionization.

Regulatory Hurdles: In some regions, regulatory frameworks for copper-silver ionization are not as well-established as those for chlorine. Navigating regulatory requirements and obtaining necessary approvals can be challenging for operators considering this technology.

Future Prospects and Innovations

Advancements in Copper-Silver Ionization Technology

Improved Electrodes and Control Systems: Ongoing research and development are focused on improving the durability and efficiency of electrodes used in ionization systems. Advances in materials science can lead to longer-lasting electrodes that require less frequent replacement. Additionally, smarter control systems with automated monitoring and adjustment capabilities can enhance the performance and reliability of copper-silver ionization.

Hybrid Disinfection Systems: Combining copper-silver ionization with other disinfection technologies, such as ultraviolet (UV) light or ozone treatment, can provide a multi-barrier approach to water disinfection. Hybrid systems can offer enhanced pathogen control and improved water quality while minimizing the drawbacks associated with any single method.

Potential for Integration with Other Systems

UV and Ozone Combination: Integrating copper-silver ionization with UV or ozone treatment can provide complementary disinfection benefits. UV light effectively inactivates microorganisms by damaging their DNA, while ozone provides powerful oxidation. Combining these methods with copper-silver ionization can create a robust and comprehensive disinfection system.

Smart Pool Management Systems: The future of pool management includes integrating disinfection technologies with smart monitoring and control systems. Internet of Things (IoT) devices and advanced sensors can provide real-time data on water quality, allowing for precise and automated adjustments to disinfection processes. This integration can optimize the performance of copper-silver ionization and other disinfection methods, ensuring consistently safe and clean pool water.

Research and Development Needs

Long-Term Health Impact Studies: Further research is needed to fully understand the long-term health impacts of exposure to copper and silver ions in swimming pool environments. While current evidence suggests that these ions are safe at recommended levels, comprehensive studies can provide more definitive conclusions and inform regulatory standards.

Optimization of Ionization Parameters: Research focused on optimizing ionization parameters, such as electrode configurations, current levels, and water chemistry adjustments, can improve the efficacy and efficiency of copper-silver ionization systems. Understanding the interactions between ions and various pool water conditions is crucial for maximizing disinfection performance.

Environmental Impact Assessments: Studies assessing the environmental impact of copper and silver ion discharge from pools can inform best practices for managing and mitigating any potential ecological effects. These assessments can guide the development of environmentally sustainable disinfection practices.

Conclusion

Strange noises such as grinding, squealing, or banging coming from the motor are often indicators of internal damage or wear. These noises can signal issues with bearings, impeller, or motor components, and should be investigated promptly.

Decreased Water Circulation:
Reduced water flow or poor water circulation in the pool is a common symptom of a failing motor. If you notice weaker jets, sluggish water movement, or uneven distribution of water through the pool’s return lines, the motor may be struggling to maintain proper circulation.

Motor Overheating:
Excessive heat emanating from the motor housing or a noticeable increase in motor temperature during operation indicates overheating. This can be caused by various factors such as motor overloading, blocked ventilation, or electrical issues, all of which can lead to motor failure if left unaddressed.

B. Troubleshooting Steps Before Deciding to Replace
Before jumping to the conclusion of replacing the motor, consider the following troubleshooting steps to diagnose the issue:

Check Power Supply:
Ensure that the pool pump is receiving adequate power supply from the electrical source. Verify that the circuit breaker or fuse associated with the pump motor has not tripped or blown.

Inspect and Clean Filter and Strainer Basket:
A clogged filter or strainer basket can restrict water flow and cause the motor to work harder, leading to overheating and decreased performance. Remove and clean the filter cartridge or backwash the sand or DE filter. Also, clean out any debris from the strainer basket.

Inspect Pump and Motor Connections:
Examine the pump and motor connections for any signs of leaks, loose fittings, or corrosion. Tighten loose connections and replace damaged seals or gaskets to ensure proper water seal and prevent air leaks.

Check for Obstructions:
Inspect the pump inlet and outlet ports, as well as the impeller, for any obstructions such as debris or foreign objects. Remove any blockages that may be hindering water flow and causing strain on the motor.

Monitor Motor Performance:
Observe the motor during operation and note any abnormal behavior such as excessive vibration, erratic operation, or unusual odors. These signs can provide valuable clues about the underlying issue affecting motor performance.

By performing these troubleshooting steps, you can determine whether the motor issue can be resolved through simple maintenance or if replacement is necessary. If the motor continues to exhibit symptoms despite troubleshooting efforts, it may be time to consider replacing it to ensure optimal performance and prevent further damage to your pool pump system.

First of all, you should gather information on your current motor

A. Locating the Motor Specifications

Check the motor label, typically located on the side or back of the motor housing. The label provides essential information such as model number, manufacturer, electrical specifications, and sometimes a wiring diagram.

User Manual:
If available, refer to the user manual or documentation provided with your pool pump system. The manual may contain detailed information about the motor, including specifications, maintenance instructions, and troubleshooting tips.

B. Key Specifications to Note

Horsepower (HP):
Horsepower indicates the motor’s power output and determines its ability to circulate water effectively. Note the horsepower rating of your current motor, which typically ranges from 0.5 HP to 3 HP or higher for larger pool systems.

Voltage:
The voltage rating specifies the electrical supply required to power the motor. Common voltage options include 115V, 230V, or dual-voltage motors that can operate on either voltage. Ensure that the replacement motor has a voltage rating compatible with your pool’s electrical system. Please note that wrong voltage supply can soon burn a new motor out, so please pay attention to the voltage rated on the motor to make sure it is the same as your power supply. Apart from the volts, Hertz is also important, usually the Hertz in North America and most of the South America, Saudi Arabia, Korea, Philippines and some other Countries are 60Hz and the motor will run at 3450RPM while the rest have the Hertz of 50 and motor will run at 2880RPM.  

Frame Size:
The frame size refers to the physical dimensions and mounting configuration of the motor. Common frame sizes for pool pump motors include 48-frame and 56-frame. Match the frame size of the replacement motor to the existing motor to ensure compatibility with the pump housing and mounting brackets.

Service Factor (SF):
The service factor indicates the motor’s ability to handle temporary overload conditions without overheating or sustaining damage. It is expressed as a decimal or percentage, with typical values ranging from 1.0 to 1.5. Higher service factor ratings indicate greater overload capacity. The Rated Horse Power multiplied by SF equals the total overload capacity(called THP) of a motor, so it is better to get a new motor that has an equal or larger THP than your current motor to avoid overheating or damage.

AMPS:
Max amps of a motor also indicates the capacity of the motor. It is strongly recommended that the replacement motor should have an equal or larger max amps than your current motor to avoid overheat or damage. 

By gathering this essential information about your current motor, you can accurately select a compatible replacement that meets the requirements of your pool pump system. This ensures smooth installation and optimal performance, minimizing the risk of compatibility issues and ensuring efficient water circulation.

How To Reduce Pool Water Flow Without Replacing the Pump

How To Reduce Pool Water Flow Without Replacing the Pump

Written by Catherine Zhou on Oct. 31st 2023

Every pool owner knows the importance of a pool pump in maintaining the health and clarity of their pool water. However, there are times when the flow from the pump might be more than necessary, leading to wasted energy and potential wear on the equipment. In this guide, we’ll explore ways to reduce your pool pump’s flow without replacing the entire pump.

At its core, a pool pump circulates water from the pool, through the filter, and back into the pool. The flow rate, measured in gallons per minute (GPM), indicates how much water the pump circulates. Several factors, including the pump’s size, design, and settings, influence this rate.

Benefits of reducing pool pump flow are as below —

Energy Savings and Cost Reduction: A reduced flow means the pump works less, saving energy and reducing your electricity bill.

Extended Equipment Lifespan: Less strain on the pump can extend its lifespan.

Improved Water Quality: Proper flow ensures efficient filtration and better water circulation.

Methods to Reduce Pool Pump Flow

Adjusting the Pump’s Settings

Most modern pumps come with adjustable speed settings. If you have a variable-speed pump, simply reduce the RPM to decrease the flow. For dual-speed pumps, switching to the lower speed can help.

If your pump is single speed, you can reduce the size of the impeller, sourcing a proper impeller is a good way, if new impeller is not available, you may take out the current impeller and reduce the diameter of the impeller by grinding with a tool. Usually the width of the impeller influences pump flow and the diameter of the impeller influences pump lift and flow, so reducing the diameter of the pump will also reduce the lift.

Installing a Bypass Valve

A bypass valve allows a portion of the water to return to the pool without passing through the filter, effectively reducing the flow. Install the valve after the pump and adjust it to achieve the desired flow.

Using a Flow Control Valve

This valve, installed on the return line, lets you control the amount of water returning to the pool. By adjusting this valve, you can manage the flow rate effectively.

Adjusting the Return Jets

Return jets push water back into the pool. By angling them differently or partially closing them, you can influence the flow rate.

Reducing your pool pump’s flow can lead to significant benefits, both in terms of cost savings and equipment longevity. With the methods outlined above, you can achieve an efficient flow rate without the need for a pump replacement.

How to find the right pump for your pool on Amazon?

How to find the right pump for your pool on Amazon?

Written by Catherine Zhou

When your current pump quits, you will have to source a new one. Some pool owners think it is expensive to buy from pool shops or pool contractors, so they may consider to it online like Amazon, Ebay, or other online shops.

pool pumps online

Yes, I do think pumps on Amazon is a cost efficient choice for pool owner who is good at DIY. However, you may spend a lot of time and energy to find a proper one for your pool, see, so many choices that seem all suitable for your pool? If you made a wrong decision and got a wrong pump, a lot more effort should be put in to return it and perhaps the free return period has expired when you finally realize that the pump is not compatible with your pool, so finally you probably get a pump from local pool shop at high cost and an improper pump from Amazon as a sunk cost which will lay in your utility room forever.

But don’t worry, there are always ways to save money and get great deals.

In this article, I will tell you how to source a proper pool pump from Amazon and save every coin in a good manner. These conclusions are based on my 10-year experience in pool industry as well as my observation and practice for years.

pump motor label

First of all, you have to find out some key points of your old pump, these key points usually includes voltage, horse power and water flow(flow rate). In some pump, the water flow is not indicated. It doesn’t matter, voltage and horse power are basically enough.

Voltage

If the label on your old pump shows it is dual voltage 115/230V, you will have to find out the exact power supply that feeds to the pump. Please check with a professional electrician. Usuallt 115V wires consist of a hot line(mainly black), a null line(mainly white) and a ground line(mainly green). 230V wires consist of two hot lines and a ground line. Wrong voltage to a pool pump will soon burn out the motor. So before you place order on Amazon, please make sure that the pump voltage is in accordance with the power supply you are going to feed to the pump.

Horse Power/Flow rate

The reason why I put these two parameters together is that they both indicates the size of the pump. These two parameters are positively correlated. So you might only find one of them on the pump label in some swimming pool pumps.

If your old pump is listed as 1.5HP, do you think it can be replaced by a new 1.5HP pump? Now, please pay attention, some name brand pumps will have a SF(service factor) shown on the label as well. There is a formula: HP×SF=Total HP(THP). If the SF of your old pump is 1.3, its total horse power is 1.5×1.3=2.0HP, that means your old pump is actually a 2.0HP pump.

performance curve

Now let’s turn to the pumps listed on Amazon, as far as my observation and discovery based on several pool pumps I’ve bought from Amazon, I realize that the non-brand-name pool pumps sold online usually shows HP directly with SF 1.0 which means their HP equals to THP. So you may have to choose the 2HP one.

Wait, do you think all is over? Not yet! I find out that some sellers list larger HP than the real pump THP so as to sell it at a higher price . So, if the pump listing shows it is 2HP, the real pump may only 1.5HP or even smaller. You may have a question: How do I know its real HP???

My solution is to check the weight of the pump. Usually a 1.5HP(here means THP) pump will have a gross weight around 14kg(31 pound) or heavier, and a 2.0HP(here means THP) pump will have a gross weight around 15kg(33 pound) or heavier.

Another solution is to compare the dimension of the pump. It is normal that the dimension varies during pumps from different brand, but if the new pump is 50% smaller than your old pump, be aware, it is obviously irrational!

If you have any better solution on this issue, welcome to discuss with me via email info@jademotor.net or my face book https://www.facebook.com/jadepooltech

what you see and what you get

In pool industry, many pool contractors match pumps with pools according to the flow rate, they usually recommend to finish each circle within 3 hours, that is to say, the pump flow rate(GPH) should be 1/3 of your pool size if we do not consider the influence of the sand filter here. I have checked the listed flow rate of many pumps on Amazon and finally realize that many sellers mark the flow rate too much larger than the real pump flow.

Take inground pool pumps(self-priming) for example, usually a 1.0THP pump impeller can move water around 4800GPH(80GPM), a 1.5THP pump impeller can move water around 5300GPH(88GPM), a 2.0THP pump impeller can move water around 6000GPH(100GPM). If you saw a 2.0HP pump that has water flow less than I listed above, that is probably because the manufacturer wants to run the motor in a lower power so as to keep the motor cool and result in a longer lifespan, if you met this kind of pump, it is definitely a good product! However, if a 1.5HP inground pool pump shows 8000GPH or more, please bounce off the page immediately, do not waste your time on a product with such an exaggerated description!

Congratulations! You are almost done to make correct decision on a new pump, the last thing you should consider is the local regulation on pool pump. People live in California may see the warning in red words on the right of the page: This item cannot be shipped to your selected delivery location. Please choose a different delivery location. That’s because the pump doesn’t meet energy efficiency requirement of CEC(California Energy Committee), you may have to find a CEC-compliant one.

Those are all my experience of sourcing pool pumps on Amazon or other online shops. Feel free to let me know if you have any more questions.

Can Pool Pump be Used for Pond?

Can Pool Pump be Used for Pond?

Written by Catherine Zhou

A pool pump is a type of mechanical water pump that is used to circulate water in a swimming pool. The pool pump is typically located outside the pool, and it uses a series of filters and pipes to circulate the water. The pool pump is responsible for circulating the water, keeping the pool clean, and providing filtration.

We have recieved many inquiry from users wondering whether the pool pump can be used for pond.

The answer is: yes. A pool pump can be a great addition to a pond, providing much needed circulation and filtration. Most pond owners are familiar with the problems that can arise from stagnant water, including algae growth and foul odors. By circulating the water, a pool pump helps to keep oxygen levels high and prevent the buildup of harmful toxins. In addition, a pool pump can be used to operate a UV filter, which will help to kill bacteria and algae. As a result, using a pool pump in a pond can greatly improve water quality and make the pond a more enjoyable place for both people and wildlife.

 

However, there are a few things to keep in mind before using a pool pump in your pond.

First, pool pumps are designed to operate on a closed system, so they may not be able to handle the larger volumes of water in a pond. Please make sure the pool pump is powerful enough for your pond.

Second, pool pumps are often made of plastic, which can degrade over time when exposed to sunlight and chemicals. So it is better to place the pool pump under a sunshade or something similar.

Finally, pool pumps typically require a higher level of maintenance than other types of pond pumps. Usually pool pump has a filter basket in the strainer housing, it can filter out big mess like leaves, but smaller mess will go through and might pile up in the impeller,  if things go on like this, the impeller and motor might be trapped, and the lifespan of the pool pump will be shorter. We suggest to use a more precise filter screen before dirty water goes into the pump to prevent small mess going into the pump.

If you’re considering using a pool pump in your pond, be sure to weigh the pros and cons carefully before making a purchase decision.

Self-priming and non self-priming pool pumps: definition and application

Self-priming and non self-priming pool pumps: definition and application

Written by Catherine Zhou

In the new Dedicated Purpose Pool Pump regulation which took into effect on July 19th 2021, all the pool pumps are sorted into self-priming and non self-priming, which has different energy efficiency standard to meet. Generally speaking, the DPPP rule has more strict energy efficiency standard on self-priming pool pumps than that of non self-priming pool pumps. But how do we know if a pool pump is self-priming or not?

Definition

Strictly speaking, all the pool pumps are not self-priming according to the traditional definition of self-priming since all the pool pumps are centrifugal pumps. There are no seals between the suction and discharge sides of the pump. This means that centrifugal pumps are ineffective with air and are not capable of evacuating air from a suction line when the liquid level is below that of the impeller. In such cases, the pump is said to be air-bound and there is a danger of overheating: generally, pumps rely on the pumped fluid to lubricate and cool the pump’s bearings.

But the DPPP rules did sort the pool pumps into self-priming and non self-priming, let’s see how it defines: Self-priming pool filter pump means a pool filter pump that is certified under NSF/ANSI 50–201515 to be self-priming or is capable of re-priming to a vertical lift of at least 5.0 feet with a true priming time less than or equal to 10.0 minutes, when tested in accordance with NSF/ANSI 50–2015, and is not a waterfall pump.

DoE-Compliant Max Power Eco

DoE-Compliant Giant Force Pro

Application

The DPPP rule also suggests that, usually an inground pool pump is regarded as self-priming and an above ground pool pump is regarded as non self-priming. This makes some pool owners quite upset: my inground pool pump seems non self-priming according to the definition of the DPPP rule, do I have to replace it?

I would say, no need of that. The definition of the DPPP rule is for energy efficiency standard, it will not have any effect on the performance of the existing pool pumps. In pool industry, before the DPPP rules took into effect, usually we regard those high vertical lift & low flow rate pool pumps as self-priming and those low vertical lift & high flow rate pool pumps as non self-priming. If the pool pumps can meet the energy efficiency requirement of DPPP rule, you can still use non self-priming pool pump on your inground pool as long as the water level is as close to the pump’s vertical lift. In other words, if the water level is far below the pump’s vertical lift, we suggest to use a check valve to prevent air going into the suction line.

In conclusion and suggestion to pool pump distributors: If the pool pump you are selling meets the DPPP rules, you can still sell them as previously despite the pump is self-priming or not, please keep your sales strategy as before.

If you have any more questions, we, as a professional pool pump manufacturer, are happy to help at any time!

Is Solar Power Pool Pump A Good Investment?

Is Solar Power Pool Pump A Good Investment?

Written by Catherine Zhou

Solar pool pumps are a popular choice for pool owners looking to reduce their carbon footprint. Is it a good investment to buy a solar power pool pump? Solar pool pumps typically cost more than traditional electric pool pumps. In addition, solar pool pumps require a sunny location for optimal performance. If your pool is located in a shady area, you may not get the full benefit of the solar pump. Moreover, solar pool pumps rely on batteries for backup power, which can add to the cost of ownership. For these reasons, solar pool pumps may not be the best choice for everyone. Before making a decision, it is important to weigh the pros and cons of solar pool pumps to see if they are right for you.

It is more expensive to install solar pump than regular pool pumps

Solar pool pumps are becoming increasingly popular, but they come with a higher price tag than traditional pumps. Solar pumps are powered by the sun, which means they can save homeowners money on their energy bills. In addition, solar pumps are more environmentally friendly than traditional pumps because they do not produce emissions. However, the initial cost of a solar pump can be upwards of $ 1,000, making it a significant investment. In addition, solar pumps require regular maintenance and replacement of parts, which can add to the overall cost. For homeowners who are considering a solar pool pump, it is important to weigh the upfront costs against the long-term savings. While solar pumps may have a higher initial price tag, they can save homeowners money in the long run.

The return on investment a solar pump may not worth it

A solar pump is a device that uses solar panels to convert sunlight into electrical energy, which is then used to power a water pump. Solar pumps are often used in remote locations where there is no access to the electrical grid. While solar pumps can be a viable option in some cases, they are not always the best choice from a financial perspective. Solar pumps typically have a higher initial cost than traditional electric pumps, and they also require regular maintenance and replacement of parts. As a result, the return on investment for a solar pump is often quite low. In many cases, it is simply not worth the investment to install a solar pump.

solar power pool pump

In some houses, the house owners installed many solar panel to supply power from the sunlight, in these cases, a traditional pool pump is enough since the power supply from the terminal already comes from the solar. 

If you’re looking for a pool pump that will save you money in the long run, and your house are not completely covered by the solar panel, you can consider a variable speed pump. Variable speed pumps use less energy than traditional pool pumps, so they will save you money on your energy bill. In addition, variable speed pumps are more durable and require less maintenance, so they will save you money in the long run.

Here’s some choice for you:

Possibility 6: No power supply or improper power supply

Solution: Make sure power is on and the voltage ranges in 90%–110% of the rated voltage.

Possibility 7: Broken timer

Solution: If pump connects to a timer, make sure it works

Possibility 8: Trapped motor

Solution: Open the motor back cover and rotate the shaft manually to see if it is clogged. Usually clogged impeller or trapped rotator can lead to trapped motor, check both of them to determine the final problem.

Problem 2: Pool Pump Motor shuts off

Possibility 1: Overload or overheat protection is activated

Solution: Allow the motor to cool down and restart it after 30 minutes. If problem still exists, check if the amperage reading is over the rated current when pump is working. If so, check if there’s any blockage on the impeller or strainer basket, clean it up and restart the motor.

Possibility 2: Motor capacitors are damaged

Solution: Change new capacitors with the proper voltage & capacitance ratings.

Possibility 3: Wrong wiring size or extension cords

Solution: Replace the current wires or cords with sufficient sized ones.

Possibility 4: Low voltage

Solution: This could happen in some area where the voltage supply is not stable. If possible, use a voltage regulator to provide more stable voltage for the motor.

Possibility 5: Motor overheating due to damage in violent transportation. This could happen when the pump is source online and delivered by express.

Solution: Open the motor back cover and check if any part is deformed or not. If so, change new parts and restart the motor. If it can not be repaired, change the whole motor.

Problem 3: Pool Pump Motor hums but can not start.

Possibility 1: Centrifugal switch stuck in OPEN position

Solution: Use a small stick or other objects to move the switch to CLOSED position.

Possibility 2: Trapped impeller or motor shaft

Solution: Motor shaft can be rotated manually to check if it is trapped. Usually impeller is the main reason to cause this problem, open the motor back cover and check if impeller is OK or not.

Problem 4: Pump can not prime

Possibility 1: Pump hasn’t been primed properly

Solution: Make sure pump strainer housing is filled with water. Check to see if strainer cover is sealed properly without air leakage.

Possibility 2: Blockage in the piping system

Solution: Check if there’s any blockage on the inlet and outlet of the pump, clean it up if necessary. Make sure all necessary valves are in open position and the water can circulation freely.

Possibility 3: Air leaks in the piping system

Solution: Check all the joints and make sure they are tightened.

Problem 5: Low water flow

Possibility 1: The filter screen or suction pipe is blocked or restricted

Solution: Remove all the sucked object and make sure water can go through the plumbing system smoothly.

Possibility 2: Pipe not big enough for more water to go through

Solution: Usually 1.5” pipe allows a maximum flow of 45GPM, 2.0” allows a maximum flow of 80GPM and 2.5” allows a maximum flow of 110GPM. Make sure the pipe size you used is proper to the pump rated flow.

Possibility 3: Filter pressure too high due to dirty filter media

Solution: If pump connects to a sand filter, backwash the sand filter; If pump connects to a cartridge filter, replace the cartridge.

Possibility 4: Leakage from the pump lid or connectors/fittings

Solution: If air leaks in suction pipe, pump will rumble constantly. Tighten the pump lid or fittings, if any of them is damaged, replace immediately.

Possibility 5: Abnormal Suction line or discharge line

Solution: If the suction line is longer than 25 ft, or has more than 4 elbows, it will significantly reduce the flow. Also check if there’s any kink on the discharge line which could also lead to low flow rate.

Possibility 6: Leak at any joint

Solution: Please refer to possibility 3 in problem 3.

Possibility 7: Low pool water level

Solution: If the pool water level is lower than half of the skimmer opening, it will cause low flow rate. Fill up the pool to proper water level and check if the problem persists.

Problem 6: Pump is noisy

Possibility 1: If you hear grinding noise, it might be caused by an object caught in the impeller

Solution: Turn off the power and check if there’s any object caught in impeller. Remove it and restart the pump.

Possibility 2: If you hear humming noise, it might be caused by low voltage

Solution: Please refer to possibility 4 in problem 2.

Possibility 3: Worn out bearings

Solution: Bearings are important to the motor, once they are damaged, the whole motor will be noisy. The only solution is to replace the motor.

Possibility 4: Worn out impeller or voluteSolution: Once impeller or volute is worn out, it will cause water to leak from the pump and make noise. The only solution is to replace the impeller or volute.

Possibility 5: Pump base vibration

Solution: Check if the base is installed properly and all the bolts are tightened. Also make sure there’s no object blocking the pump, which could lead to vibration.

Possibility 6: Foreign matters in the pump, especially around the impeller

Solution: Try to remove the foreign matters from the pump.

Problem 7: Pool Pump is leaking

Possibility 1: Water leaks from where the motor connects to the wet side.

Solution: This usually indicate the shaft seal fails. Replace it immediately.

Possibility 2: Water leaks from pump housing.

Solution: Open the pump housing to see if the O-ring is in good condition, move it to the correctly place or replace it if necessary.

Possibility 3: Water leaks from pump lid.

Solution: Open the pump lid and check condition of the O-ring, if it is not sit well in the right place, take it off and reassemble it. If it is broken, replace it immediately.

Above 7 problems are those been met most frequently by the users, I hope they can help you when your pump doesn’t work well.

What HTS Code Should I Use to Clear the Custom When Importing Pumps?

what HTS code should I use to clear the Custom when importing pumps?

Written by Catherine Zhou

When importing pumps into the United States, you will need to use a special code to clear customs. The code you will need is called an HTS code. In this blog post, we will discuss what HTS code you should use when importing pumps and provide a few tips on how to make the process as smooth as possible!

Choose a proper HTS will help to ensure that your pumps are cleared through customs quickly and without any issues. In some case, a proper HTS code will also help to save unnecessary cost you pay for your pumps.

First, you need to find out the type of your pumps. For example, our pool pumps are all centrifugal pumps, so we usually use 8413.70.2005 for our pumps with 1.5″ ports, which is called “other centrifugal pumps with discharge outlet under 5.08 cm in diameter” and 8413702015 for our pumps with 2.0″ ports, which is called “other centrifugal pumps with discharge outlet 5.08 cm or over in diameter”. Some importer will also use 8413.70.0060. This code covers all types of centrifugal pumps, including those specifically designed for pools.

For other pumps, you can find a proper HTS code under the code begins with 8413. You can choose any code you think is proper, but remember, please be honest and choose the code as proper as possible to your products. Otherwise, you may have trouble in Custom clearance.

If you are not an importer from US, you can also find a proper Custom code for pumps. Usually, the first 6 digits are universal all over the world. For example, pool pumps have a universal Custom code begins with 8413.70

For more details about the code, please consult your local Custom, I think they will be happy to help.

Why Should the Pump Motor to be Bond to the Pool Structure?

Why should the pump motor to be bonded to the pool structure?

Written by Catherine Zhou, 9 years experience in pool industry.

Some pool owners will wonder why the pool pump motor should be bonded to the pool structure when they see the instructions on the user manual.

There are a lot of benefits to bonding your motor to the pool structure. By doing so, you can improve the safety and performance of your pool pump. In this blog post, we will discuss why it is important to bond your motor to the pool structure and how to do it properly. Stay safe and enjoy your swimming season!

 

A women beside the swimming pool

When you bond your motor to the pool structure, you are essentially creating a electrical connection between the two. This helps to prevent any potential hazards that could occur if there was an electrical issue with the pump. It also helps to improve the performance of the pump by ensuring that it is getting a proper ground.

Bonding your motor to the pool structure is a fairly simple process. You will need to purchase a bonding kit from your local pool supply store. The kit will come with everything you need to properly bond the pump to the pool. Once you have the kit, simply follow the instructions and you should be good to go!

We hope that this blog post has helped you!

Dedicated Purpose Pool Pump Regulation: Why Is It Necessary?

Dedicated Purpose Pool Pump Regulation:
Why Is It Necessary?

Written by Catherine Zhou

An earthquake took place on July 19, 2021 in Pool Industry when a new regulation regarding pool pumps came into effect on that day, that is Dedicated Purpose Pool Pump Regulation.

After then, pool pumps manufactured in the USA should all meet the energy requirement which is meassured by WEF(Weight Energy Factor). 80% pool pumps disappeared due to this regulation. The rest pumps are all with high energy efficeny motors such as variable speed pumps or some capacitor operate motor pumps. As a result, pool owners will have to pay more for a DoE-compliant pool pump. Some consumers even complain about this. Let me tell you why the regulation is necessary.

One of the main reasons why homeowners should consider making the switch to a dedicated purpose pool pump is because it can help save money on energy bills. A lot of people do not realize that their regular pool pump is actually using more energy than necessary. This is because the regular pump is designed to work with a filter and a chlorinator. But when you are only using the pump to circulate the water in your pool, you do not need to use as much energy.

Another reason why making the switch to a dedicated purpose pool pump is a good idea is because it can help prolong the life of your pool pump. This is because when you are using a regular pump, there is a chance that it will overwork itself and eventually break down. But when you use a dedicated purpose pool pump, you can be sure that it will not overwork itself since it is only being used for one specific task.

So, if you are looking to save money on your energy bills and prolong the life of your pool, then making the switch to a dedicated purpose pool pump is a good idea. It is important to note, however, that you will need to purchase a new pool pump if you want to make this switch. But it will be worth it in the long run!

5 Tips You Need to Know before Importing Pool Pumps

5 Tips You Need to Know
before Importing Pool Pumps

Written by Catherine Zhou

If you are new in the market for pool pumps, you may be wondering if it is worth importing one from pool pump manufacturer overseas. Pool pumps can be expensive, so it is important to do research before making a purchase. In this blog post, we will discuss five tips that you need to know before importing pool pumps.

Tip1: How much margin you can get from this importing business.

Firstly, you should know the average retail price of pool pumps in your target market.

The price of a new pool pump can vary depending on the type and size of the pump, as well as the brands you check from. I suggest you refer to the median price of a swimming pool pump. For example, a 1.5 hp non-famous brand pool pump in US costs $200 in average and a 1.5 hp Hayward pool pump could be $800. If you are new in the swimming pool pumps market, I think it is better that you refer to the price of non-famous brand pool pumps.

Secondly, research the cost of the pump from different oversea manufacturers.

In China, prices can vary widely depending on the quality of the pump. I saw some complaint on amazon saying: you’ll get what you pay for. This is also true when it comes to source pool pumps. Please do not focus on the lowest price listed on some B2B websites. I suggest you also refer to the median price of these suppliers. Usually trade companies’ quote will be higher than that from factories, this is normal since the trade companies usually provides with better service than that of factories. 

However, I do see some factories that supply good service or even better service than trade companies, if you meet one of these amazing factories, work with them immediately! Let me tell you more, Ningbo Jade Pool Technology Co., Ltd. is one of these factories supplying energy efficient pool pumps and trustworthy service, why not contact us now?

Let’s come back to the point. Based on my 9 years experience in pool industry, usually the direct factory price of a non-famous 1.5 hp pool pump ranges from $90 to $150 for bulk orders based on volume.

Thirdly, find out if there are any import duties or taxes that will be applied to the purchase.

In order to find out if there are any import duties or taxes that will apply to your purchase, you will need to contact the local customs authority. They will be able to provide you with information on the applicable rates and how they are calculated. We usually use HS code begins with 841370, this is a universal number in the world, the rest numbers will be different in different Countries. Please check with the customs authority agency.

Fourthly, consider the shipping costs from the supplier to your Country.

It is important to know the exact dimension of pool pumps from the supplier since the sea freight is mainly calculated accroding to the dimension of goods. Usually a 40′ HQ container space is 68CBM which can carry 1200 pumps. So if you know the cost of the 40′ HQ container, you will know the shipping cost of each pump. The sea freight fluctuates sharply in recent years, please check the lastest shipping cost with your forwarder or ask them for a cost efficient solution in transportation.

Tip2: Which pump type is more popular?

Based on pool type

There are inground pool pumps and above ground pool pumps in the market. Usually, an inground pool pump has higher lift than above ground pool pump, and it is called “self-priming”; An above ground pool pump has bigger flow than inground pool pump of the same HP, but it is not self-priming, it should be located below the water level.

Inground Pool Pump

Above Ground Pool Pump

You will also have to know the percentage of in-ground and above-ground swimming pools existed in your Country. In US, 65% of the swimming pools are inground type and 35% are above ground type. Those data is for private pools instead of commercial swimming pools So maybe you should consider imporing more inground pool pumps than above ground ones.

Based on speed

There are single speed, two-speed and variable speed pool pumps available. In US residential market, two-speed pool pumps take up 55% of the total market and single speed only has about 20% since two-speed can save energy costs a lot. So maybe you should consider importing more two-speed swimming pool pumps than single speed pump.

There’s also another pool pump type which seems more popular than previously when pool owners consider to source energy efficient pool pumps, that is variable speed pumps. More and more people prefer variable speed since the energy cost becomes more expensive year by year, but the market share is still not quite big due to its relatively high cost. So you may also consider to import variable speed swimming pool pump to diversify your business. As far as I know, there are not so many Chinese factories(Less than 3 factories) have the ability to manufacture a perfect variable speed pump. I’m pround to say that our factory — Ningbo Jade Pool Technology Co., Ltd. is one of those who makes amazing variable speed pumps, we developed the 1st variable speed pump in 2015, during 7 years improvement, now our variable speed pump is quite user friendly, and has received plenty of good reviews from thousands of pool owners. Many distributors benefit from dealing with our variable speed pumps. If you are also interested, please contact us immediately for more details.

Tip 3: Please note the electric power supply specification in your Area.

Here are some main specifications that you should focus on. Fail to follow may cause trouble in your pool pump business.

Voltage and Frequency

Wrong voltage or frequency can burnt the pump motor easily. You will have to find our the voltage and frequency supplied in your Country. For example, the voltage in US is 110-120V/60Hz and 220-230V/60Hz, usually 110-120V power supply needs a power plug while 220-230V doesn’t. Most inground swimming pool pumps are supposed to be wired with 220-230V power supply and most above ground pool pumps require 110-120V supply. So, you can save the power cord cost by offering inground pool pumps without power cord.

Power Plug Type

There are also various plug types in different area. For example, the plug type in US is NEMA, In Europe, the voltage is 220-240V/50Hz and the plug type is Schuko or BS. The wire size could be different as well. You will also need to find out if a GFCI (ground fault circuit interrupter) is required in your Country. If you get these information wrong, the customer will be very confused.

 

Tip 4: The plumbing specification of your Country

The suction and discharge port size of the pool pump is usually standardised to be mm or inch in diameter. You will need to check with your local plumber or pool builder what is the most popular size they are using. This is because different Countries have different plumbing standards.

For example, in US residential market, the pipe size is usually 48mm(1.5 inch) in many old houses and 60mm(2.0 inch) in mang new houses. But in Europe, people use 50mm and 63mm pipes. Wrong size pump ports can be a big problem for your business. But don’t worry, our factory has worked with customers from all over the world, we have rich experience about the pipe size in difference areas. 

Moreover, you’d better also check if the fitting to be used on the pool pump you imported is easy to source in local shop, this is an important point that pool owners will consider when they are searching pumps. No one wants to replace the whole pump because of a fitting problem. We offer various fitting types for our pumps, you may keep some spare parts as well as fittings in stock in case required by the end user.

If you want to know more about plumbing suggestion, please feel free to contact us. We are glad to help no matter you are interested in our products or not.

Tip 5: Find out the regulation in your Country to sell pool pumps

There are certain standards that pool pumps have to meet in order for them to be sold in a Country. You will need to find out what these standards are and make sure that the pump you are importing meets these standards.

Safety Standards

This is a base standard for electrical products, you have to prove the products will not cause serious injury to end users via safety test by authorized labs. For example, in US, the CSA (Canadian Standards Association) and ETL (Intertek) certification is required. In some other Coutries, CE, SAA, SGS could also be a mandatory certificate.

Energy Standards

You should also check if there are any other special regulations in your Country that you need to be aware of. For example, in US, the pool pumps have to be DoE-compliant in order to be sold. This is an energy efficiency regulation which took into effect in July 19th, 2021. Please double check with the supplier if their products are approved by all the mandatory regulations.

We hope these tips could help you a little bit in your import decision. If you have any other questions, please feel free to contact us. Our team would be happy to assist you further. Thank you for reading!

What if a big pump works with a small plastic sand filter?

What if a big pump works with a small plastic sand filter?

This article is a summary between one of our customers in Saudi Arabia and our salesman.

Fay Wang from Ningbo Jade Pool Technology Co., Ltd.

By Fay Wang

Today, one of our distributors in Saudi Arabia meets a problem. His customer finds that the 1.0hp pump flow becomes smaller after running it for 5 months. He opened the pump and find that there is a lot of sand heap up in the impeller.

tripped impeller

“It is very dusty in our area, we are not able to avoid the dusty going into the pump, how should I do?”

The distributor asked for help.

Well, if it is impossible to stop the sand going through the pump, then a bigger pump might be helpful since it has bigger centrifugal force to send the sand or dust out of the impeller.

The distributor agreed with our proposal since this problem never happen in our 1.5hp or bigger pumps. But the only question is, can the 19″ plastic sand filter work with a 1.5hp or bigger pump? The distributor is afraid the 19″(500mm) plastic sand filter can not bear the pressure that a 1.5hp pump produces.

After calculation, David, Jade’s general engineer, thinks it is workable.

Usually we advise 1hp pump to work with a 19″(500mm) sand filter, 1.5hp with 24″(600mm), 2hp with 31″ and 36″ sand filter.

But it is also changeable in some situation.

Usually a plastic sand filter can bear max pressure of 21kg. The working pressure of our 1.5hp pump is 14kg and the max pressure it can reach is 18kg when locked, it is less than 21kg, so it is ok to run 1.5hp pump with a 19″ sand filter just considering the pressure.

Of course we should also consider flow rate, energy consuming etc. for more useful suggestions.

If you have any question on those data or you also meet any special situation on the pump and sand filter, please feel free to let us know, we will give proper suggestions.

Thanks for reading this article!

How the Energy Crisis will Affect Our Production?

How the Energy Crisis will Affect Our Production?

By Catherine Zhou

Oct. 15 2021

power crisis

I think most of you have heard about the energy crisis all over the world.

In order to face the crisis, we Chinese factories have been asked to recude work time so as to save energy.

We have been informed by many of our material suppliers that they will work 4 days and stop for 3 days a week from now on. Some evern work 2 days and stop for 5 days a week. 

So, in the near furture, the leading time of our suppliers will be longer than before and result in the longer leading time of our products.

Usually our leading time is 30-45 days, but in the near future, the leading time might be 45-60 days if there’s no stock in our warehouse. This situation will exist until the energy crisis is alleviated.

We do suggest our customers to prepare for orders much ealier than previous. But we will also keep some stock to make sure our customers will not wait too long.

Please feel free to contact me if you are interested in our products.

Pool Size and Pool Pump Horse Power

Pool Size and Pool Pump Horse Power

This article shows how to choose the right pump for your pool

staff of Jade

By Vincent Hao

Many pool owners are confused on how to match the right pool pumps for their pools.

There are many charts from different professionals and gives different suggestions, it make things more complicated.

Actually, it is easy to decide how big pump will work for your pools. Usually we advise to run your pool water 3 cycles a day and each cycle should take 3-4 hours, and it is better to run pump 200 days of year.

Based on the above concept, pool owners should choose pool pump with flow rate instead of just horse power as the same horse power pumps can perform different flow rate.

For example, if your pool is 14400 gallon, a pool pump with 4800GPH(14400/3=4800) will be suitable for you, which is equal to 80GPM(4800/60=80).

Flow rate is affected by the pipe size. Please choose the right pipe when doing plumbing.

Here’s a chart on the proper pipe size and flow rate.

Pipe Size

1.5″ (50mm)

2.0″ (63mm)

2.5″ (75mm)

3.0″ (90mm)

Biggest Flow

45 GPM

80 GPM

110 GPM

160 GPM

If you have any more questions, please feel free to ask our customer service staff for more information: info@jademotor.net

If you are willing to buy a pool pump for your pool, you may check our catalog for a proper pump:

Why my pool appears green or pink?

Good to know

Why my pool appears several colors?

If your pool appears green,

forest

algae might not be the culprit. Your pool water could appear to be several colors because you have metal present in the water, which the chlorine has oxidized. So, instead of green algae, your pool could have copper in it. If your pool has a reddish tint to it, your pool water probably has iron in it. Purple or black tints suggest your pool water might have manganese in it.

DoE-compliant Jade Pool Pumps

DoE-compliant Jade Pumps

View this page to know more about DoE-compliant Jade Pool Pumps

The U.S. Department of Energy (DoE) has developed new energy-efficiency standards for pool pumps manufactured on or after July 19, 2021.

As was mentioned in previous post, pool pumps should meet minimum WEF after July 19, 2021. Jade has sent all the pool pumps to a qualified and authorized lab to have them tested for WEF.

Fortunately, some of the pumps meet the minimum WEF required by DoE without any improvement. The rest pumps should be improved and re-designed to make them DoE-compliant.

Use the following tables to find DoE-compliant Jade Pool Pumps.

What’s the difference between HHP and THP?

about New doe regulation IN THE USA

What's the difference between HHP and THP?
How to know the WEF of a pump?

Please do not get confused with HHP and THP. Here is an article showing the difference and based on that it would be quite easy for you to understand what is going on. I am just quoting it here:

HP, THP and HHP in DoE Regulation

Everything depends on HHP instead of THP.

The pump can be single or variable speed as long as it is fulfilling the DoE new criteria, it is good which is shown in DoE’s table below.

To make it simple, you just need to calculate the HHP of the target pump and if it falls between the range of 0.711 to less than 2.5 then apply the relevant formula to calculate the WEF and compare if the measured WEF is equal to greater than calculated WEF. If it is so then the target pump will qualify for the new DoE rules.

US DoE DDDP Refulation

If you would like to test a pump to see if it meets the WEF requirement, first you will have to calculate the C curve and hhp and then do the rest of the testing based on single speed or variable/multiple speed and then calculate the WEFs. If they meet the minimum allowable WEF score as shown above in the table then they qualify new DoE rules otherwise they just fail the new regulations. 

Fortunately, most of Jade’s pool pump WEF is bigger the minimum allowable WEF score, that is to say, Jade pool pumps are allowed to be sold in the USA, the only thing you have to do is to regist on the DoE website as a distributor of our pumps before selling.

Any more questions, please feel free to let us know at info@jademotor.net

Thanks for your attention!

 

About DPPPs Rule – How to calculate HHP?

About DPPPs Rules - How to Calculate HHP?

HHP means Hydraulic Horsepower, it is calculated as pressure times flow rate and divided by a coefficient.

Here’s the formula:

HHP=P*Q/1714

HHP is in unit of hp, it reflects output of the pump.

P is the pressure with unit of psi.

Q is the flow rate with unit of GPM.

Take Jade product J15001 pump for example, the pump has a flow of 92 GPM at 35 psi, then its HHP is calculated as 35*92/1714=1.88

Note: above psi and GPM data is based on test performed in Jade’s own lab. Should any discrepancy occur between this data and other test result from any authoritative lab, the data from the authority shall prevail.

In kilowatts, the formula of the hydraulic power should be HkW=P*Q/2298 

HkW is in unit of kW, it reflects output watts of the pump.

P is the pressure with unit of psi.

Q is the flow rate with unit of GPM.

What You Need to Know About Weighted Energy Factor for Pool Pumps

What You Need to Know About Weighted Energy Factor for Pool Pumps

Updates on Pool Pump Changes

As a pool owner, you want an energy-savings, environmentally-friendly swimming pool. You may wish you could easily estimate your energy and cost savings before purchasing a pool pump. Fortunately, this is all possible with the new weighted energy factor scheme! The new weighted energy factor regulations from the Department of Energy (DOE) will make it even easier for pool owners. Here is what you should know.

What is weighted energy factor (WEF)?

WEF ratings are very similar to how we measure the efficiency of a car in miles per gallon (MPG). A WEF rating will allow you to see and compare the energy efficiency of different pool pumps so that you can make an informed choice when purchasing. The higher the WEF rating, the more efficient the pump.

When is this change happening?

By July 19, 2021, all newly manufactured pool pumps that are included under the new rule must be tested and labeled with their WEF rating.

What does this mean for pool owners?

By establishing a WEF rating, your pool pump shopping just got easier. You will now have the tools to easily evaluate and compare how efficient new pumps are. In turn, this will help you reduce the energy you consume to run your pool, resulting in much lower monthly energy bills.

What does this mean for pool pump distributors?

Well, why not hurry up to look for a cost efficient and energy efficient variable speed pump and grab a spoon from this opportunity!

Here’s a good choice for you!

Variable Speed Pump On A Seasonal Pool

Here’s some summary of the article

Are you wondering if it is worth it to get a variable speed pump if you live in an area where you pool is not open year round? This is an argument that I see being raised whenever I post a video or article talking about the advantages of getting a variable speed pool pump. It used to be that the most commonly sited objection was that “I only run my pump for a few hours per day” which implies that a variable speed pump would not have any savings in this circumstance. In response to this objection I wrote an article that breaks down this comparison to show that variable speed pumps are better even under this extreme filtration example. You can watch the video and see this detailed breakdown in this article about running a pool pump 4 hours per day.

As shown in that article running your pump for even a few hours at maximum speed will use more power than a properly scheduled variable speed pump. The drop in power consumption as you reduce the RPM of the motor is so significant it can reduce electrical costs for filtration on pools that have even the most scant filtration schedule. This leads me to the point of this article, in that it is common to see people say that seasonal pools will not benefit as much from variable speed pumps as pools located in a year-round environment. I believe this is a matter of perspective and variable speed pumps are just as important on seasonal pools as they are on year round pools.

Variable speed pump costs – The first item to clarify is pool owners often say that a variable speed pump costs $1000(Jade variable speed pump cost is far below this amount, send inquiry to get the lastest price) so how long will it take to recoup this cost? My problem with this statement is that it completely ignores that single speed pumps are not free. You need a pool pump no matter what and even though a variable speed pump is more money than a single speed pump to buy, it is the difference between these two numbers that you should be concerned with when making this comparison. It is also worth noting that the cost of variable speed pumps in general has been reducing steadily since they hit the market a decade ago. While some of the larger and more expensive models are well in excess of $1000 to buy, these would also correspond to very high end and fancy pools with a lot of features that need to be run by the pump. Expensive pools need expensive pumps and this should be a surprise to nobody. On the entry level of the market there are now many variable speed pumps that are far less than $1000 to buy. An example of this would be the Pentair Superflo VS pump which is (as of this writing) for sale on Amazon for $729 where the single speed version of this pump is $428 which means the difference in price is only $301 and not $1000 or more dollars.

So now we are asking the right questions, like will a seasonal pool save money with a variable speed pump, at least enough to make up the difference in price between a replacement single speed pump and a new variable speed pump. My stance is that a variable speed pump is every bit as important for seasonal pools as they are for pools that operate year round. The once concession that I would be willing to make is that it will take longer to recoup the costs for a variable speed pump on a seasonal pool than it would for a pool that runs the pump 365 days per year. That being said pool pumps are rated for 60 months of operation from manufacturers. A pool in a seasonal area might take 10 years or more to reach 60 months of operation, where a year round pool could reach that service life expectation in half that time.

A 25,000 gallon pool in a cold climate area of Canada and a 25,000 gallon pool in Florida both require a similar amount of filtration as established with the industry standard of three to four turnovers of a pool being required every 24 hours. This means that upgrading to a variable speed pump will have the potential to save the exact same amount of electricity for both of these pools. As shown by manufacturers of VS pumps, and from articles like this one about how much power does a pool pump use, pools with single speed pumps can reduce electrical use by as much as 80% to 90%. It does not matter where the pool is located, or how many months per year the pool operates, each pool has the same ability to benefit from upgrading to an energy saving variable speed pump.

Both seasonal and year round pools benefit from variable speed pumps – Even though it will take longer for a pool in a colder climate to recoup the investment in their variable speed pump, a pump that only operates for half the year or less will still be in operation long after a pump in a year-round climate has reached the end of its service life and required replacement. Of course all of this is a moot point since as of July 18, 2021 it will be law for all pools to have a variable speed pump for the filtration pump (or a pump that meets an efficiency requirement that currently can only be fulfilled by variable speed pumps). This means when your current pump fails you will be required to upgrade your pump. This is not a move to save you money on electricity. The fact that you will save a substantial amount of electricity is secondary to the point of eliminating wasteful, energy hog appliances that have better option available. Thinking green starts at home, and arguing against variable speed pumps reveals that you have not done the math on the electrical savings potential, and refute changes that undoubtedly will improve the energy footprint of owning a swimming pool. Variable speed pumps are useful on every swimming pool that currently has a single speed pump regardless of where that pool is located, and how many months per year you get to use it.
