Pool Pump
A pool pump is the mechanical device that circulates water through the filter, heater, and chlorinator, maintaining water movement and filtration.
Definition
A pool pump is the mechanical device that circulates water through the filter, heater, and chlorinator, maintaining water movement and filtration.
Typical Values: Residential pools: 0.75–2 HP; Variable speed: 600–3,450 RPM
In Plain Language
Pool pumps create suction by spinning an impeller that draws water from the skimmer and main drain, pushes it through the filter and other equipment, and returns it to the pool through the return jets. Pump sizing must match the pool volume and plumbing resistance to achieve adequate turnover rate. Variable speed pumps can adjust their speed for energy savings while maintaining adequate circulation.
Why It Matters
The pump is the heart of the pool system. Without adequate circulation, no chemical treatment can maintain water quality.
