The Pentair 400023Z Impeller Assembly is a genuine OEM replacement component designed specifically for 5HP WhisperFlo XF pool pumps. As the heart of your pump’s hydraulic system, the impeller plays a crucial role by moving water through the pump housing and into the filtration and circulation system.
When an impeller becomes worn, cracked, or chemically eroded, flow performance drops and overall system efficiency suffers. Replacing the impeller with the correct OEM assembly restores proper water flow, enhances pressure stability, reduces strain on the motor, and extends the life of your WhisperFlo XF pump.
