Things to Consider

Choosing the right pool pump seems like a simple endeavor but this can’t be farther from the truth. While there are many products on the market that purport to be most effective, not all of them are right for you. To avoid going through scores of products and wasting cash, it is imperative that you keep some essential factor in mind before purchase. Here are a couple of things that you should consider when buying a variable speed pool pump.

Main advantages of variable speed pool pumps

Variable speed pool pumps are popular home equipment that offer a lot of benefits to pool owners. This is because they were designed to improve on the single-speed pumps that are less efficient and have high energy costs. That said, here are a couple of advantages of a variable speed pool pump.

  • Energy Efficiency- Variable speed pumps save energy for several reasons. First, they use a permanent magnet motor that does not need additional electricity to spin the rotor. Secondly, variable speed pool pumps do not work with a single pumping speed. This allows them to reduce their flow rate and overall energy consumption. They can regulate the speed of the motor when the pool is idle.
  • Durability- pool pumps with variable speeds tend to last long because of some of the design differences. For example, most motors in variable speed pumps are totally enclosed and fan cooled. This protects them from harsh environmental conditions unlike single-speed motors that have exposed induction motors. Enclosed motors not only stay cooler but also preserve the motor bearings and windings.
  • Easy to Install- it is easy to install a variable speed pump and you can even transfer the wiring from a single speed motor to your new pool pump. Programming is also a piece of cake for most variable speed pool pumps. However, not all pools are same and you will have to customize your settings depending on your preferences. You will have to run some experiments to find the minimum operating speeds and to set out the different run times.
  • Silent operation- Unlike traditional pumps, variable speed pool pumps run more quietly and it may be difficult to tell the pool is running when at low speeds. One of the reasons for silently operating is because the motors are enclosed and the sounds may be muffled inside.

10 Outstanding Variable Speed Pool Pumps for Quiet and Efficient Work

How do they work

A pool pump is an essential equipment that works by circulating the water in your pool. It does this to ensure that the water does not stay still and that any unwanted debris is filtered out. The regular pumps often run with one or even two speed settings, which may be impossible to control.

A variable speed pool pump works by addressing some of the challenges that these single or two-speed pumps have. They have an automatic feature that regulates the speed of the motor while it is still running. How do they do this? Variable speed pool pumps have a pressure sensor that reduces the speed of the pump when there is low water pressure. Instead of just running one speed setting in a session, a variable speed pool pump will detect and set the speed required to get the job done. This video gives more information about how variable speed pool pumps work and why you should get one:

Price range

Like all products, it is important that you review the price range of variable speed pumps before setting out to get one. You want a product that will offer you the best bang for your buck and one that is within your budget. That said, a good variable speed pool pump should be affordable but it should not compromise on quality. Of course, a pricier model such as the Hayward TriStar VS W3SP3202VSP will offer you more features and better performance. But this does not mean that you should splurge on the most expensive pump pool. Carefully review each selected product and the features they offer before looking at the price of the pumps. If you are on a tight budget then you can try the Harris In-Ground VS, our best value pick.

Features to consider while buying the best variable speed pool pump

A long-term decision such as buying a variable speed pool pump requires some careful considerations. With so many pumps on the market, it may be difficult to find the right product. These are some of the important features to keep in mind before you pull out your credit card to get a pool pump.


Both the internal and external materials that make up a pool pump are important. The pool pump that you choose should be able to protect the equipment from natural vagaries. This is because they protect important components from being soaked while at the same time enhance durability of the pumps. A strong material means that the pool pump will be highly durable and you can rely on it for years. It is also important that the material used by the manufacturer is not easily corroded.

10 Outstanding Variable Speed Pool Pumps for Quiet and Efficient Work

Power and efficiency

One of the main reasons to get a variable speed pool pump is to reduce the power consumption of your pool equipment. There is no reason for your pump to be running throughout the day even if they need to keep your pool clean. In the event that you are not filtering your water, a variable speed pump will ensure the pump runs slowly in such times. For best results, you should get a variable speed pool pump that can automatically adjust its speed settings to reduce power consumption.

Ideally, you need a powerful pool pump that will be able to handle all your pool needs. Those with a large-size pool should get a pump with more horsepower such as the XtremepowerUS 75035-1 or the Harris In-Ground VS 72522. These pool pumps have a high 3-horsepower operation. You will have to review your electricity consumption after the first month to establish whether it is efficient. Watch out for any product that has an Energy Star certification as it is likely to be very efficient too.

Speed range

Speed is essential in any swimming pool pump. Some pool pumps have a single speed setting while some have two or more speed settings. Variable speed pool pumps have up to 8 different speed settings to help you clean your pool. The Pentair 011028 IntelliFlo VS is a great choice if you are looking for a versatile machine as it comes with an 8-speed setting. You can also choose the Pentair 342001 if you would like a simpler machine. This variable speed pool pump comes with a 3-speed setting control. It is worth noting that a higher speed setting will allow you to turn over a high amount of water over a short period of time. If this is your aim then you should look for pumps with higher speeds.

Easy installation

Several manufacturers will void your warranty if you do not get a professional to install your variable speed pool pump. Some companies do not have this restriction so you need to be sure about this first. A lot of users complain about this since it is not only inconvenient but hiring a professional also requires a lot of cash.

However, we believe that most variable speed pool pumps are easy to install and won’t present any challenges during installation. You should be able to install your pumps and rewire it as soon as you read the manual instructions. Just to remember to check if your manufacturer will punish you for self-installation by voiding your warranty. The XtremepowerUS 75035-1 is one of the products we reviewed that had simple installation instructions.

10 Outstanding Variable Speed Pool Pumps for Quiet and Efficient Work


A guarantee or a warranty gives you extra peace when you buy a product. That said, you should ensure that you get a product that is covered by a warranty for a reasonable amount of time. Some products such as the Pentair Sta-Rite 343001 SuperMax VS and Pentair 011028 IntelliFlo VS have a 60-day guarantee. While this period may be enough to test out the pump and report how it is working, we feel that you should get a long-term warranty just in case things go wrong. The Hayward SP26115VSP Super Pump VS is one of the products in the review that has a one-year limited warranty. You should also ensure that you are conversant with the terms and conditions of the warranty to ensure it does not get void.


Safety is very important when choosing a variable speed pool pump. We recommend that you get the poll pump with most safety features. These features help to protect your equipment and other sensitive parts such as the motor from electric shocks and other risks.

One of the most important safety features that we found was a safety vacuum release system. With this system, the pool pump will prevent any unnecessary substances from clogging the pump. Not all pool pumps have this feature, but the ones that do will automatically shut down when any unwanted objects get into the pump. Other models such as the Pentair 011018 IntelliFlo have an on board diagnostics system that alerts the user in case there is a problem with the pump.


Variable speed pool pumps are generally more durable than the single or double speed pool pumps. One reason is because the VS pumps have motor fans that are not only fan cooled but they are also enclosed. The other types of pool pumps make use of a standard induction motor that may not have as much protection. These motors have exposed vents that may allow water and other debris to enter the pump and cause damage.

The variable speed motors also stay much cooler because they have fans. Consequently, the bearings and even motor windings will not experience much wear and tear. It is these little design differences that make variable speed pumps to be more durable. If you are looking to get the most durable product then you can try out the Harris In-Ground VS 72522, which is made from stainless steel.

10 Outstanding Variable Speed Pool Pumps for Quiet and Efficient Work

Ease of use

All the power and extra features that variable speed pool pumps offer are useless if the user does not know how to operate the machine. This is why it is important for you to get a user-friendly variable speed pool pump. Your user should be able to program the machine without experiencing significant challenges. We noted that many people do not configure their pool pumps well leading to poor performance and extra power costs.

Remember that you are getting a variable speed pool pump to reduce your energy consumption and enhance performance. A user-friendly pool pumps such as the powerful Hayward SP26115VSP Super Pump VS or the simple Pentair 342001.

Extra features

The best pool pumps come with some extra features. Variable speed pool pumps, to be specific, integrate several technologies and different systems. For example, some pool pumps come with a technology that can monitor and modify flow settings. These pumps will automatically increase circulation of water immediately there is a need for a regular flow of water. Not all pumps are compatible with this constant-flow software. Some pumps will require a manual input when a new task is initiated. However, other variable speed pumps can use the constant-flow software to detect and raise pump flow without any extra effort.

Noise levels

It is important that you consider the amount of noises that your pump will be making. This is quite important if the pump will be situated right next to the pool or if you are getting a pump for a public pool. While there are some variable speed pool pumps that are a bit noisy, most run silently. This is because these pumps are fitted with permanent magnet motors that are enclosed. The motor uses less energy and any noise produced is trapped inside. We found the Pentair 011018 IntelliFlo to be quite silent as it produces a sound output of only 45 dB when running.


10 Outstanding Variable Speed Pool Pumps for Quiet and Efficient Work

This review will not be complete without discussing about horsepower. A lot of people consider the horsepower of a pool pump before they get one but they do it for the wrong reasons. Variable speed pool pumps come in different horsepower. More powerful models such as the XtremepowerUS 75035-1 or the Harris In-Ground VS 72522 have an impressive 3 HP. Other models such as the Hayward SP26115VSP Super Pump VS have little horsepower with an output of 0.85 HP. That said, you should not always go for the highest horsepower.

Be sure to buy a variable speed pool pump that is within your required calculations. Having a pool pump that has more power than necessary will just increase your power consumption. A more powerful pump may also lead the equipment to its early grave by overwhelming the other systems or by increasing the amount of cavitation.

Pipe Size and Flow Rate

It is easy to overlook the pipe size of your pool pump when shopping for a new machine. Finding the right pipe size is, however, important as it can affect the overall performance of your machine. Most pipes will range from 1.5 inches to 3.0 inches and you will have to find the one that fits perfectly. We recommend that you get a larger pipe if you have a large pump and a smaller size pipe if you have a relatively small pipe. Your pipes can get damaged if you do not follow this rule of thumb. This is because a large pool pump with a small pipe may strain the pipes when a lot of water is moving through the pump.

Similarly, you also need to know the flow rate of your pool pump if you want maximum efficiency. The flow rate of a pump is measured in gallons per minute and represents the amount of water that circulates through the filter in every minute. You should know your ideal flow rate as well as the maximum and minimum flow rate of your pool pump.


As highlighted before, you need a pool pump that fits perfectly to the size of your pool. A larger pump in a small pool may end up wasting more energy in the long run while a small pump in a large pool will easily get overloaded. That said, you will have to do some mathematic calculations to be able to size the variable speed pool pump. A pool pump should run for a minimum of eight hours a day for maximum cleaning. You then need to divide the volume of water in your pool (gallons) by eight to find the amount of water that your pump should filter in an hour. If this is divided by sixty (60) then it gives the number of gallons per minute that your pump should handle. You will then have to add up the lengths of the different suction lines and divide them by the number of lines. You can then use this information to size your pool as required. It is worth noting that perfect sizing is necessary to optimize pumping and filtration.

Maintaining a variable speed pool pump is not a difficult task but it will require some effort from your part. You should note that the pool pump is meant to be out with the elements and you should not try to cover it or plant trees around it. Leaks and moisture are some of the common culprits that will cause your pump to malfunction. You should call for immediate repairs as soon as you notice even the smallest leaks. It is also important to protect your pool pump from chemicals as the fumes may end up damaging the pump overtime. Regular cleaning is not necessary if you keep chemicals and other dirt away from your pump. If cleaning is necessary, you can use a damp cloth but you should never apply water directly.

The RPM of each pool pump ranges starkly and will depend on a number of factors. These include the size of the pool, the size of the pump and the max flow per minute that the pump prescribes. Once you find this, you can calculate the turnover rate and flow rate required for the pump. This is then divided by the number of minutes in a day that you intend to run the pool to give you the perfect RPM.

How long you should use your pump in a cycle will ultimately rely on two things. These include filtration and chemical demand. In certain time such as during summer, your pool will be at its peak and you are much more likely to experience increased impurities in your pool. This will require that you run the pump for longer. As a rule of thumb, you should run your pool pump for an hour and half for every 10° F of the outdoor temperature. Pool professionals recommend that you run your pool pump for a minimum of four to five hours during winter. You should run the pool for at least 12 hours if it is the hot summer months.
