Benefits

The Swimmables SW-21-006 impeller helps bring a compatible pool pump back to proper water movement and pressure. A damaged or worn impeller can cause low flow, poor circulation, reduced filter pressure, noisy operation, and added strain on the motor.

Replacing the impeller during a pump rebuild can help improve pump performance and extend the life of the wet end when the motor, diffuser, seal plate, and shaft seal are still in good condition.
