Best pump motors Buying Guide

Buying a pump motor isn’t the same as purchasing a pool pump. A pump motor is a part of a pool pump motor, and you do need to make sure that the model you buy fits and improves the performance of your pool pump. But to do that, you do need to understand some considerations. They include:


One thing that you should never forget checking is the compatibility of the pump motor with your existing pool pump. You need to verify that it fits the model of your pool pump. To do that, you need to use the pump’s model number found on a sticker on the old motor enclosure.

Also, consider the impeller used on your pool pump. If you need to upgrade your single speed to a variable speed motor, then you will need to change the impeller too. That also applies if you want to improve the unit from low HP to a high HP pool pump motor.


For you to have a better performance with your pool pump, you have to make sure you buy a replacement or upgrade motor of high-performance. But how will you test this? You will have to check on some factors like the type of capacitors on it and safety features.

A motor capacitor is an energy storing device ideal for motor starting or running. A motor can have either start capacitor, a run capacitor, and even both. The type of capacitor the model uses will tell you how energy efficient the model will be as well as the ability to handle hard functions.

Mostly an upgraded motor should feature a capacitor start/capacitor run system. Models with this type of system perform better with improved energy efficiency and heavy-duty handling.

Motor Enclosure

In general, there five types of enclosures, namely Open Drip-Proof (ODP), Totally Enclosed, Fan Cooled (TEFC), Totally Enclosed, Nonvented (TENV), Washdown (WDN) and lastly Explosion-Proof (XPRF).

The ODP enclosed motors feature an open enclosure, and they are more suited for indoor and clean atmosphere use. They have a ventilator opening which prevents liquids and reliable from entering while also letting the heated moisture out.

The TEFC enclosed motors do feature an external fan that circulates the cold outside air to the engine to cool it down. They are well suited for heavy-duty operation requiring long operating hours.

The TENV motors don’t have any air openings. However, this motor’s construction is not liquid or airtight, allowing air to move in and out freely.

The WDN enclosures, on the other hand, are designed to work correctly in all environments and requires regular cleaning and sanitization – more maintenance.

The XPRF motors are entirely enclosed. The design allows it to withstand any internal explosion of gas or even vapor. The motor frame doesn’t rupture or burst. They are, however, ideal for use with safe operation in those hazardous environments.


Durability is another thing you need to consider while deciding on the motor to buy. Check on the materials used in making the shaft and the enclosure. The construction elements should be high-quality, rust, and corrosion-resistant. That way, they have the chance to last for long, thus preventing you from replacing it soon.

Motor Service Factor

Motor Service Factor, the SF, is the multiplier percentage that a pump motor can handle in a short period when operating within the average voltage and frequency. It’s a fudge factor which offers extra horsepower when needed.

While operating a motor at its limit exposes it to overheating, a service factor allows a pump motor to run below its maximum. That will enable it to offer continuous performance with a cooler winding temperature at a given load leading to extended life and improved reliability. So, the higher the service factor, the better.

Frequently Asked Questions (FAQs)

Do I need to lubricate my pump motor?

Yes, but not the whole motor. The part that needs lubrication is the pump motor bearings. They do rotate in contact, and for them to last long and also not rust, you need to lubricate them often.

Why does my motor shutoff after long hours of operation?

Your pump motor might be featuring a thermal overload feature which cuts of the current if there is overheating. After long hours of operation, the motor winding temperature might increase triggering the safety feature.


While a different pump motor is fitting a different model, you must pick a model that is made for your pool. Ideally, every pump motor brand will advise you to enter your pump’s model number to see if it’s compatible.

Never forget to check as it might not fit properly or be forced to replace it soon than expected. With all the information I’ve provided you with, nothing should stop you now from getting a suitable replacement or upgrade your pool pump motor. Good Luck!
