The Best Pool Pump Motor

To ensure a clean and safe pool there are steps to be taken one of which involves the installation of a quality swimming pool pump.

However, sometimes the motor could require a replacement. Are you one of those asking what is the best pool pump motor to buy? While there are many options to consider, we have narrowed it down to only the best. But before then, let’s consider some buying guide.

Buying Guide

Before making a buying decision, consider the following factors:

Size of Pool

Swimming pools come in various sizes and designs depending on the architecture of the pool. If it’s a big pool, then you will require a massive pump with the biggest voltage. This in turn affects the electricity consumption as the bigger the voltage, the more electricity the motor will consume when pumping water.

The same also applies to a small pool; it requires a small pump with less voltage and will consume less electricity. Hence, it is important to determine the size of your pool before making a purchase.

Pump Maintenance

This is another factor that must be considered before making a purchase. While some pumps can be repaired and replaced after breakdown some others do not offer such option as once defective, it stops working. 

Also, consider the overall cost of maintaining the pump. If it’s much cheaper to buy one with a replacement option, then purchase that. 

Cost of Pump

Various pump brands have their price tags and while it’s true that overspending on a pool pump will hurt your finances seeing as you have other expenses to make, you shouldn’t also settle on less than the best just to cut cost.

The best thing to do would be to invest in a pump that offers great value at an affordable price. Create a budget and stick to it.

Installation Process

It is necessary to consider the installation process. While some pumps require professional installation owing to their size, motor, complexity and operation, some others have an easy installation process.

If the pump you hope to buy will require a professional to install it, it then means you will be spending more, this is good though as it ensures a great job will be done but if you are on a budget, you should consider one with an easy installation which will not require external personnel. This saves money, time and energy.


Ultimately, no one wants to buy an under-performing pump, hence it is necessary to consider the motor and other additional features that ensure the pump will work efficiently.
