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.

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.

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.

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:

In this blog post, I will introduce top 7 common pool pump problems that people met in using pool pumps and the solution on how to fix them. Hope this blog will help more users to fix the pool pump trouble and operate their pumps more easily and smoothly.

Problem 1: Pool Pump Motor will not start

Possibility 1: Wrong wiring

Solution: Check the wiring of your pump, rewire it if necessary. Please read the instructions carefully and follow it strictly.

Possibility 2: Loose electrical connection

Solution: Check all the circuit connection points and make sure all the points are well connected.

Possibility 3: Switches or relays not closed

Solution: Closed the swtiches and relays properly.

Possibility 4: Tripped circuit breakers or GFCI’s

Solution: Check to see if there’s electricity leakage on any point, if so, repair it and then restart the breaker.

Possibility 5: Fuse is open

Solution: Change a new fuse with the proper ampere & voltage.

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.

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!

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.

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?

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.

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.

By |February 7th, 2020|Uncategorized

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!

Why do I need a variable speed pump

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.
