Pumps are an essential component of any swimming pool, choosing one can prove to be difficult, and diving headfirst into pumps and their specifications can be confusing. We have written this guide to help you simplify the process and explain exactly what the pump will be doing, and how to work out which pump you need.
A swimming pool pump circulates the water throughout the pool’s network, it removes any suspended solids, purifying the water. The main components of a swimming pool pump are the housing, the motor, the impeller and the strainer. The housing will contain all the components for the pump, the motor is situated at the back, and is used to power the impeller; the impeller is the force behind the pump which pulls the water through, and the strainer is used to catch any debris from going through the pump.
The first thing to consider is the size of your pool, you will need to work out the volume of your pool in order to find the correct sized pump. Volume is calculated by multiplying the length, width and depth of your pool.
This is the amount of liquid volume can pass through your pump, after working out the volume of your pool, this number will need to be multiplied by 2 and then divided by 1440 to get your LPM (litre per minute) calculation. This will be the flow rate you need in your pump.
Your pump will either have a single or three phase motor. Single phase versions can be directly connected to the electrical supply system, but typically have a short life span. Three phase models are usually more compact, produce less vibrations and have a longer life span.
If your pool is heated, your heat pump is seperate from your swimming pool pumps. Your swimming pool pump will filter the water first, it will then pass through your heat pump before returning to the pool.
Your pool’s filter size and your pump’s size should correlate, if they don’t then unnecessary strain can be added to the pump, shortening its life span, so it is important to ensure your filter’s flow rate matches your pump’s.
