About This Item

The Pentair Diffuser (350033Z) is the OEM replacement diffuser for EQ Series Commercial Plastic Pumps in the 7-1/2 HP and 10 HP configurations — covering models EQ750, EQK750, EQKT750, EQ1000, EQK1000, and EQKT1000.

The diffuser channels flow from the impeller into the pump volute, converting rotational velocity into pressure. A cracked or worn diffuser reduces hydraulic efficiency and can cause loss of prime or cavitation. Replacing it with the correct OEM part restores designed flow performance.

Compatibility is based on Pentair parts documentation and available OEM records. This is not an exhaustive list. For certainty, verify the part number in your equipment's manual or on the original part itself before ordering.

Pro Tip

Before ordering, locate the part number molded or stamped on your existing diffuser and confirm it matches 350033Z. EQ Series pumps span multiple HP configurations and model variants — diffuser geometry is HP-specific. Ordering by model number alone is not sufficient; always cross-reference the part number on the component being replaced.
