How do Pool Pumps Work?

Our swimming pool water needs to be clean and healthy for us to swim. Many parts work to keep the pool tidy.

Pool pumps, also known as water pumps, keep the pool running. This part works with the pool’s filter to keep the water clean.  While a robotic pool cleaner cleans the entire pool, a pool pump makes the water fit to swim.

When you have a pool pump installed, it pushes the water out of the pool through the filter and the water heater before returning it to a warm and clean pool.

Main Components Of A Pool Pump

Impeller

The impeller is the most essential and the only moving part of the pump. It is attached to the motor shaft that makes it spin and pushes the water forward. There are three types of impellers: open face, semi-open face and closed face.

Pump Basket

This basket collects the large debris once the water runs and removes small particles, small twigs and leaves.

Water Discharger

It discharges water from the pump into the filter and thoroughly cleans it, just like the best pool covers.

Motor

A motor converts electrical power into movement and spins the motor shaft. There is a stator winding inside the motor that produces a rotor winding and an alternating magnetic current. This is in turn, creates torque and rotates the shaft.

Pump Seal

Also known as a mechanical seal, this device prevents water from leaving out of a centrifugal pump. Keep in mind to never lubricate the pump seal or run it dry.

Pump Housing

It is also known as a pump strainer which covers O ring seals to prevent the air from entering the house pump. Before we get into the process, check out our pool cleaner reviews.

How Does A Pool Pump Work?

A pool pump is technically a centrifugal pump as they work on the centrifugal force, meaning water moving away from its center force. For the water circulation, The best pool pumps have an inlet and an outlet.

The water travels from the pool through the main drain and the skimmer. Skimmers are rectangular inlets located at the top of the pool. It is fitted with a filter to keep the debris out. The water pulls through the skimmer and down into the pump once it turns on.

The pump motor shaft powers the impeller. It then spins the volute and creates a high velocity of the water—a vacuum forms when the water propels towards the outer edge of the impeller.

How Does A Pool Pump Work?

When the volute changes velocity and creates energy, it causes the water to flow through the plumbing filtration system. It cleans all the debris and containments present in the water.

The water gets pumped to the water heater and warms it before releasing it back into the pool.

When your pool pump does not perform at total capacity, you need to inspect the O rings and mechanical pump seal. As these parts can disintegrate over time, it causes air to leak, which lowers the vacuum amount. The pump motor can also wear out after a few years. In such instances, you can easily replace the motor instead of buying a new pool pump.

A pool pump is found in every pool, whether it is a residential or an above-ground pool. You will also need regular pump servicing to keep your pool pump running.

 

My name is Ron Walsh. I’m an industry expert, certified pool technician, and avid lover of all things aquatic. In my beautiful homeland of Florida, where I still reside today, pools are everywhere. Needless to say, I learned to love water at a young age. With my love of water, and pools in particular, it was only natural that I follow a career path in the swimming pool industry. If there’s someone to learn about above ground pools, pool cleaners and maintenance from, it would definitely be me. If you have any question just let me know.
