Product Overview

The Pentair 073129 WhisperFlo pump impeller is a critical internal component responsible for moving water through the pool circulation system. Mounted on the pump motor shaft, the impeller spins at high speed to draw water into the pump and force it through the discharge port, supporting continuous circulation and filtration.

Designed specifically for WhisperFlo pump models with 1.5 HP full-rated or 2 HP up-rated motors, this impeller maintains the proper hydraulic balance inside the pump housing. Its precision-molded construction ensures proper alignment with the diffuser and surrounding pump components, helping restore efficient pump performance during routine service or repair.
