About This Item

The Hayward Diffuser (SPX1616B) is the OEM replacement diffuser for the Hayward Super Pump High Efficiency pump series, restoring proper hydraulic flow through the pump's wet end.

The diffuser directs water from the impeller eye into the pump's discharge port, converting velocity into pressure. A worn or cracked diffuser reduces pump efficiency and flow performance — replacing it with the OEM part returns the pump to factory hydraulic specifications.

Compatibility is based on Hayward 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.

Poolaroo Pro Tip

When servicing the pump wet end, inspect the diffuser O-ring at the same time. A damaged diffuser often signals wear on adjacent components — checking the impeller and shaft seal while the pump is disassembled can prevent a repeat service call.
