How Do Pool Pumps Work?- A Brief Explanation

How do pool pumps workPool pump, the heart of your favorite swimming pool, plays the most important role for your pool. If the heart is okay, all is well!

So you should be eager to know how do pool pumps work. It will help you to be a PRO of pool pump maintenance. It’s not a big deal, we are here to make you understand how they are working for your pool every single day!

Let’s start!

What’s the job of your pool pump?

Can you guess why we addressed the pump as the heart of your pool? Because it circulates the pool water. Yes, circulation! It’s like your body. Your body is 24/7 circulating blood and so do the pump.

It circulates the pool water and pushes it to the filter. Not only to the hater but it also pushes the water to the pool heater and the chlorinator.

This is how the water can be filtered, heated and sanitized. Even the pool pump has a basket to collect debris and make the water neat and clean. Now, the water is fresh and it will be right back to the pool.

So, that’s it! That’s exactly how your pool pump carries the flow of water.

What types of pool pumps exist and how differently they work?

Pool pumps work differently depending on what type of filter you do have. Let’s know the three, available types of pool pump and their works.

Single-speed pool pump

This one will pump your water at only one, constant speed. It’s quite inexpensive to purchase and install. But, about operating, it’s very expensive.

Single-speed pool pumps implement the job in a great way. They provide the flow for equipment and turn over the water properly.

Two-speed pool pump

This one is better in pools with water features. It’s more energy-efficient than a single-speed pump. High and low, it runs into these two speeds and, guess how to adjust between the speeds?

An automation system does it. The energy usage will be dropped when you slow down the pump to the lower speed. As you can see, if you switch your single-speed pump to the two-speed one, you can save almost 80% of the pool’s energy bill!

Variable-speed pool pump

In one word, INTELLIGENT! Yes, this one is more steps ahead of the earlier two. It can automatically change the speed and can handle any complex pool application.

Another impressive thing is, you will get a crazy pocket-saving offer! Do trust or don’t, it can save up to 90% on your pool’s energy bill. It also does a better job to filter the pool water.

So, these are the different types of pool pumps. You can choose the one that’s the best fit for you. After that, you should grow an idea about when to start and replace your pool pump.

How is the physical structure of a pool pump?

Your pool pump will have a big, rounded part at the front and extended at the backward named strainer pot. The strainer pot remains covered with a lid.

What a strainer pot does is to prevent debris from entering the pump assembly and clogging the impeller. A spinning impeller (inside the pool pump) pulls the water in from the pool.

So, the thing is, the water first hits the strainer spot which is dedicated to catching any major debris. After the pool water goes through the strainer pot, the impeller will push it on to the filter.

So, these are the major factors you should know about your pool pump. After knowing all of it, you may glance over the pool pump maintenance for taking proper care of it.


Our discussion is at the furthest point. We tried to show you the whole picture of a pool pump and its job.

Is it still a huge question to you, how to pool pumps work? Definitely not, right? We broke down all of the important terms and factors you need to know about a pool pump.
