About This Item
The Pentair Diffuser (400010Z) is the OEM replacement diffuser for the MAX-E-PROXF, WHISPERFLOXF series and IntelliFlo XF variable speed inground pumps. For exact match, see the model numbers below.
The diffuser channels water from the impeller and converts rotational velocity into pressure, directing flow efficiently toward the pump outlet. A cracked, worn, or damaged diffuser reduces hydraulic efficiency, increases energy draw, and can cause cavitation that accelerates wear on the impeller and other wet-end components. Replacing it with the correct OEM part restores designed flow performance.

Pro Tip
The part number 400010Z is molded into or stamped on the original diffuser. Confirm this number on your existing part before ordering — the MAX-E-PROXF and IntelliFlo XF series use high-horsepower wet ends, and diffuser geometry is specific to the HP rating group. The fit_notes confirm this part covers the 8HP, 12HP, and 30HP variants across all confirmed model suffixes; if your model number is not listed above, cross-reference your equipment's parts manual before purchasing.
