Restore lost head pressure and steady water circulation by replacing your worn hydraulic component with the genuine Pentair 350033Z Diffuser. Engineered specifically for Pentair’s EQ Series commercial pump platforms, this OEM part directly replaces cracked, eroded, or degraded diffusers that compromise pump priming and overall system efficiency.

Fits select 7.5 HP and 10 HP configurations, including the EQ750, EQK750, EQKT750, EQ1000, EQK1000, EQKT1000, WQ1001, EQK500, and several 50 Hz/575V variants. The housing is molded from temperature-stable PPO resin, resisting sustained chemical exposure and saltwater corrosion under continuous commercial operation. An engineered bronze wear ring at the impeller interface provides a replaceable friction surface, extending shaft seal service life while maintaining precise hydraulic clearance.

Swapping a damaged diffuser requires standard pump maintenance protocols: disconnect all electrical power, isolate the wet end, and inspect the mating impeller, mechanical seal, O-rings, and bearing assembly before reassembly. This listing specifies the diffuser assembly only; sealing components and impellers are purchased separately. Backed by a one-year general warranty, the 350033Z ships unmounted for professional facility installation or scheduled maintenance cycles.
