About This Item
OEM Diffuser for Pentair Challenger and WaterFall Specialty Pumps
The Pentair 355069Z is the OEM replacement diffuser for the Challenger High Flow Inground Pump and the AFP-120 WaterFall™ Specialty Pump. If your pump is losing prime, producing reduced flow, or showing visible wear on the diffuser vanes, this is the direct replacement component.
What It Does
The diffuser channels water from the impeller into the pump volute, converting rotational velocity into pressure. A cracked, worn, or eroded diffuser reduces hydraulic efficiency and can cause the pump to lose prime entirely. Replacing the diffuser restores designed flow performance without the cost of a full pump replacement.

Pro Tip
Before ordering, locate the part number molded or stamped directly onto your existing diffuser and confirm it matches 355069Z. The Challenger line includes multiple diffuser variants sized to specific horsepower ratings — ordering by pump model and horsepower alone is not sufficient. Match the part number on the original component for a confirmed fit.
