Product details

The Pentair 356735Z is the replacement diffuser assembly for EQ Series pump models EQW300 and EQ1500, and it is also listed as 356735.

What it does

The diffuser works with the impeller inside the pump housing to guide water as it leaves the impeller. It is a service part for the wet end of the EQ Series commercial pump.

Fit and compatibility

This diffuser assembly fits these EQ Series pumps: EQW300, EQ1500, EQK1500, EQKT1500, EQK1000 EXPL PF (50 Hz) and EQK1000 (50 Hz). Read the model on the pump nameplate and compare it to this list before ordering.

Choosing the right diffuser

The 5 HP EQ Series models, such as the EQ500, are listed under a different diffuser, 350032. Do not order this part for those pumps.

Before you order

This is the diffuser assembly only. The impeller, seal plate o-ring and seals are separate parts. Sold individually.
