Pentair Diffuser | Challenger High Pressure Pump | 355270Z C7447 While the pump is disassembledThe Pentair Diffuser (355270Z) is the OEM replacement diffuser for the Challenger High Pressure inground pump, sized for the 11 2 HP Full Rated and 2 HP Up Rated configurations. The diffuser sits between the impeller and the volute, converting the high velocity water leaving the impeller into pressure. A cracked, worn, or incorrectly sized diffuser reduces hydraulic efficiency, disrupts flow through the pump, and can accelerate wear on the impeller.
