If you’re a pool owner or are considering buying a pool, you may be wondering, “What exactly does a pool pump do?” In short, a pool pump is an essential component of a swimming pool’s circulation system, responsible for moving water through the pool’s various plumbing and equipment and keeping the water clean and clear. A great analogy is to imagine that a pump acts as the heart of the pool. Let’s dive into the details of what a pool pump does and why it’s so important.

What Is a Pool Pump?

A pool pump is a mechanical device that circulates water through a pool’s filtration and heating systems. It draws water from the pool through an intake port and pushes it through a filter which removes debris and contaminants from the water. Once the water is filtered, the pump pushes it back into the pool through a series of return ports.

Why Is a Pool Pump Important?

The pump is an essential component of a swimming pool because it keeps the water clean, clear, and healthy. Without a properly functioning pump, the water in your pool would become stagnant, which would create a breeding ground for bacteria, algae, and other harmful microorganisms. This component of the equipment system also helps distribute chemicals throughout the pool, which helps keep the water balanced and safe for swimming.

How Does a Pool’s Pump Work?

A pool pump works by creating a pressure difference that moves water through the circulation system. The pump consists of two main components: a motor and an impeller. The motor spins the impeller, which creates a low-pressure area in the pump’s intake port. Water is drawn into the pump through the intake port and pushed through the filter, where debris and contaminants are removed. The filtered water is then pushed back into the pool through the return ports.

Types of Pool Pumps

There are two main types of pool pumps: single-speed and variable-speed. Single-speed pumps have one speed setting and run at a constant speed. This can be inefficient and result in higher energy bills. Variable-speed pumps, on the other hand, can be programmed to run at different speeds, which can save energy and money in the long run.

When to Replace

Pool pumps typically last between eight and 10 years, but factors like usage, maintenance, and climate can affect their lifespan. Signs that it may be time to replace your pool pump include decreased water flow, unusual noises, and increased energy bills. However, in a lot of cases, an experienced service technician can help with technical issues and keep your pump running efficiently and for a longer time than equipment that goes unattended.  There’s no doubt about it — a pool pump is one of the most important parts of your pool’s system. At Fronheiser Pools, we offer a variety of pool services, including technical visits to keep pool equipment running at its best and water quality in peak condition.
