Components of a Pool Pump

Pool pumps are made up of several components that work together to circulate water through your pool. Here are the main parts you should be familiar with:

  • Motor: The motor powers the pump and drives the impeller.
  • Impeller: The impeller is a rotating component that creates water flow by drawing water from the pool and pushing it through the filter.
  • Strainer Basket: The strainer basket is located at the front of the pump and catches debris before it enters the pump.
  • Housing: The housing contains the motor and impeller and directs water flow.

How a Pool Pump Works

Understanding how a pool pump works is key to troubleshooting common issues. Here's a brief overview of how a pool pump operates:

  1. Water is sucked into the pump through the strainer basket.
  2. The impeller spins, creating a centrifugal force that pushes water out of the pump and through the filter.
  3. Clean water is returned to the pool.

If any of the components in the pump fail, it can cause issues with water flow and filtration. For example, a clogged strainer basket can cause the pump to lose suction, while a damaged impeller can reduce water flow. By understanding how your pool pump works and the components involved, you'll be better equipped to troubleshoot issues when they arise.
