Pool Pump Buying Guide

Which pool pump is right for me? I’m an owner of a number of hotels with swimming pools so I have asked myself this questions many times. There is no such thing as one size fits all when it comes to such pieces of equipment. That is why I decided to provide a general buying guide. This buying guide is for pumps designed for swimming pools and spas. Use it to make the best choice.

Pool Pump  Buying Guide


The motor is the heart of the pool pump. It determines how efficiently it will operate. It should be rugged and engineered to work efficiently in the long term as well as in the short term.

The most important factor to consider when selecting a motor is the power it produces. When it comes to swimming pool pumps, the choice is quite large. The main power options include 3/4, 1, 1.5, 2 and 2.5 horsepower. There are less powerful motors as well. It is a good idea to base your choice of motor on the size of your pool. The larger and deeper it is the more power the pump will need to keep the water filtered and clean.

Take into account the service factor (SF) when choosing a motor as well. You can select from full rated and up rated models. The latter are more productively efficient.


The actual speed that the pool pump operates at is not that important. The important factor is the number of speeds which the device comes with. A device with two or multiple speeds is generally more energy efficient. This is because it can perform some operations at a higher speed and others at a lower speed.

For instance, you can set a higher speed so that the cleaning of the pool can be completed more quickly. On the other hand, if you want to heat your pool by the evening, you can set the pump at a slower speed so that it can run the water through the heater more slowly. That way, you will get the water heated by the time you need it and save energy.

Pool pumps with two and more speeds are generally slightly more expensive than their counterparts. However, such a pump will allow you to save money every year during its operations. The device will certainly repay the extra money invested in it.

Flow Rate

This is the most important factor to base your choice of pool pump on. The flow rate is the number of gallons that the device turns over each minute. That is why it is measures in gallons per minute (GPM).

The flow rate is directly related to the turnover. The turnover is the minimum amount of time it takes for the entire volume of water in you swimming pool to go through the pool’s filter. The turnover required for a pool of a standard size is typically 6, 8 or 12 hours. You need to pick one of these numbers to calculate the optimal flow rate for you.

In order to calculate the optimal flow rate for your pool, you need to divide the pool’s volume (in gallons) by the turnover rate (in minutes). The number is the ideal flow rate for your pool in GPM. Keep in mind that the flow rate is affected by the water resistance the pieces of equipment connected to your pool pose. Check this factor as well when selecting a pump based on the flow rate.

Energy Efficiency

You would want every device working on electric energy to be as energy efficient as possible. This is true for the pool pump as well. There are a number of features which contribute to energy efficiency. These include speed, speed control and flow rate control and motor type and design. There are different models which can save between 20 and 90 per cent of the energy normally used to run such a device.

Noise Production

Pool pumps are traditionally known to be noisy, but innovations in technology have made them much quieter. Check to see whether the motor comes with a system that provides for noise reduction such as an airflow ventilation system. It is best if the manufacturer provides data on how much noise the device produces in decibels. That way, you will be able to compare different products on the basis of this factor.

Strength and Durability

You would certainly like the device to work optimally for years to come. That is why you should consider its make to figure out how sturdy it is and how long it can last for. The internal parts of the device should be made from sturdy metal that is non-corrosive and that will not get damaged by the chemicals in pool water and by hard abrasive debris. The device should have thick plastic walls which protect it from the surrounding environment.

Additional Features

One of the desirable additional features is an oversized strainer basket with a transparent, easy to open lid. You can also consider an intelligent pump with an onboard computer that regulates the flow rate for greater energy efficiency. It also enables you to control the pump remotely and to select from different speeds and operation modes. Integrated systems for protection of the device are advantageous as well.


Now you can select the best pool pump for your pool or spa.
