About This Item
The Pentair Impeller Assembly (400023Z) is the OEM replacement impeller for the Max-E-ProXF and WhisperFlo XF series inground pumps, including fixed-speed 20 HP configurations and variable speed models.
What It Does
The impeller is the rotating component inside the pump wet end responsible for moving water through the circulation system. A worn, cracked, or clogged impeller reduces flow rate and puts strain on the pump motor. Replacing it with the correct OEM assembly restores designed hydraulic performance to your Max-E-ProXF or WhisperFlo XF pump.

Poolaroo Pro Tip
Before installing the replacement impeller, inspect the pump diffuser and wear ring for scoring or damage — these components work directly against the impeller face and a worn diffuser will reduce performance even with a new impeller in place. Consult your WhisperFlo XF or Max-E-ProXF service manual to confirm the correct torque spec when reassembling the wet end. If your pump model number is not listed above, verify part 400023Z against the exploded diagram in your equipment manual before ordering.
