what does a pool filter pump do


Author: Poolking - Swimming Pool Equipment Manufacturer


If you have a pool, you know that it takes a lot of work to keep it clean and inviting for swimmers. One of the key components of pool maintenance is a pool filter pump. In this article, we will discuss what a pool filter pump does, how it works, and why it's so important for your pool's health.

What is a Pool Filter Pump?

A pool filter pump is a device that circulates the pool water through a filter, removing debris and contaminants from the water. The pump draws in water from the pool, pushes it through the filter, and returns clean water to the pool.

How Does it Work?

The pool filter pump works in conjunction with the pool filter. The filter is responsible for trapping debris and contaminants, while the pump circulates the water through the filter.

The pump is responsible for moving water through the filter at a specific rate, known as the flow rate. The flow rate determines how quickly the water can be filtered, and it's important to make sure that the flow rate is appropriate for the size of the filter. If the flow rate is too high, the filter won't be able to catch all the debris and contaminants in the water.

There are three main types of pool filter pumps: single-speed, dual-speed, and variable-speed. Single-speed pumps operate at a consistent speed, while dual-speed pumps can run at two different speeds. Variable-speed pumps can run at multiple speeds, allowing greater control over the flow rate.

Why is it Important?

A pool filter pump is crucial for maintaining clean and healthy water in your pool. Without a properly functioning pump, the water would become stagnant, allowing debris and contaminants to accumulate.

In addition to keeping the water clean, a pool filter pump can also help extend the life of your pool equipment. By removing debris from the water, the pump helps prevent damage to the pool's plumbing and other equipment, which can be costly to repair or replace.


To ensure that your pool filter pump is functioning properly, it's important to perform regular maintenance. This includes inspecting the pump and filter for damage, cleaning the pump basket and filter, and checking the flow rate.


A pool filter pump is an essential component of any swimming pool. It's responsible for circulating the water through the filter, removing debris and contaminants, and keeping the pool water clean and healthy. By understanding how the pump works and why it's important, you can ensure that your pool is always ready for swimming season.
