About This Item

The Pentair 400020Z is the OEM replacement impeller for the Max-E-ProXF and WhisperFlo XF series inground pumps, covering the 8 HP and 30 HP model variants across all major configurations in these lines.

The impeller is the rotating component inside the pump volute that transfers kinetic energy from the motor shaft to the water, generating the flow and pressure your system requires. A damaged, worn, or cracked impeller results in reduced flow, loss of prime, and increased motor strain. Replacing it with the correct OEM impeller restores rated hydraulic performance and protects the motor from running under load without adequate flow.

Compatibility is based on Pentair parts documentation and available OEM records. This is not an exhaustive list. For certainty, verify the part number in your equipment's manual or on the original part itself before ordering.

Pro Tip

The Max-E-ProXF and WhisperFlo XF lines share common model numbers (e.g., XF-8, XF-30) — confirm your equipment's brand family before ordering. Before removing the existing impeller, verify that the part number molded or stamped on it matches 400020Z. When reinstalling, ensure the impeller is fully seated and hand-tightened against the diffuser before reassembling the volute to avoid imbalance and premature wear.
