How Does the Pool Pump Work?

by James Metts

The heart of every pool circulation and filtration system is the pool pump. Pool pumps are centrifugal pumps. Which means that they work with the principles of centrifugal forces.

Understanding how pool pumps work and how they work with the principle of centrifugal forces is just a scratch when you think of all that you can learn about these pumps. Visit this website for more.

What Is a Centrifugal Pump?

Centrifugal force is the force that pushes an object in a circular motion away from the center of the circle. This is referred to the outward force away from the circle’s axis.

This is a mechanical device designed for and used to move fluid using rational energy from one or more impellers (impellers are driven rotors used to transfer rotational energy).

Components of the Pool Pump

The pool pump is made up of three main pieces.

1. The Housing

The housing contains the filter, used for filtering water. It also contains the inverter.

2. The Inverter

The inverter is used to push water through the filter.

3. The Motor

The motor is used to power the inverter that pushes the water through the filter.

As the pump runs, the motor powers the inverter. The inverter then sucks water from the pool and pushes it through the filter.

When the water passes through the filter, the water clears up and is recirculated back into the pool.

Pool pumps are designed to run for a long period. The type of pump you have will determine how long it can run, but some poo pumps can run continuously for over 24 hours.

The filtration and circulation process can go on repeating itself over and over again. It is important to keep the process running if you want to avoid growing bacteria and algae in your pool.

Leaving your water stagnant for too long can ruin your pool water quality. However, running a single-speed pump for that long can ruin it and cost you your pump.

A variable speed pump is just the right tool for the job. It is energy-efficient, and it is capable of running for long periods at a time. No wonder it is so expensive!

Some parts of the pool pump may disintegrate over time. Parts such as the mechanical pump seal and the O-rings.

When disintegration occurs, it leads to air leakage, thereby reducing the force available to suck water from the pool into the filter for filtration.

Wear and tear can also occur in your pool pump motor. It is cheaper to replace your motor instead of buying a new pool pump.

Energy Conversions in The Pool Pump

Pool pumps are a combination of hydraulic and electric energy. In the pump, electric energy is converted to mechanical energy. This happens when the force of the water causes the impeller to start rotating.

The water is then channeled into the pump before it exits the filtration system. This is called the wet end or hydraulic end.


The pool pump which is a centrifugal pump has a simple but efficient design. And that is why it can perform its circulation and filtration processes effortlessly.
