What Is a Pool Pump?

A pool pump moves water through the pool’s circulation and filtration system using a motor-driven impeller.

How It Works

Water enters the pump from the suction plumbing and leaves under pressure toward the filter. The pump moves water; it does not replace filtration or disinfection.
