Pump basics

If you have a pool you have at least one pump. But what is the pump, what is it for and how does it work?

The pump can rightly be called the heart of your pool. It is the thing that moves water from the pool, through the filter, heater and sanitizers (if present) and back to the pool. If water stops moving in your pool it will go stagnant and algae will begin to grow.


This vital piece of equipment consists of two primary parts, an electric motor and a wet end or pump housing. The motor spins and impeller in the wet end which is the impetus for water movement. The impellor draws water from the pool via the main drains and skimmers through a pump basket and pushes it on to the filter, heater and finally back to the pool. The pump basket is a strainer that keeps larger debris such as leaves out of the impeller.

Pumps come in various sizes to match various pools. One thing to keep in mind if you are having work done on you pump, such as replacing an impellor, is that the horse power rating of the motor needs to match that of the impellor. A 2HP impellor needs a 2HP motor or larger. If you undersize the motor it will shorten the life of the motor as it will be working too hard.

Did you know you can save a significant amount of money every year by upgrading to a variable speed pump? It’s true; you can easily save hundreds of dollars a season! The way this works is two fold first the motors are built using rare earth or permanent magnets. This alone can represent a 30% savings! In addition having the ability to set exact flow rates for different tasks such as filtering, heating or water features can save up to 90%.

You can even set up different flow rates for different times of day. Wanna run a heavy filtration cycle in the morning so the pool is crystal clear in the evening for swimming? No problem. You can then turn the pump way down so you don’t hear it while swimming? These pumps can easily do this and more. Call today to find out more information and to set up installation.

Happy swimming,
