About This Item

The Hayward Top Diffuser Plate (SPX1425B) is the OEM replacement top plate for the pump diffuser assembly, designed to restore proper hydraulic function to your Hayward pump.

The top diffuser plate seats at the upper section of the pump's diffuser assembly, working in conjunction with the impeller to direct water flow efficiently through the pump volute toward the discharge outlet. When this plate is cracked, warped, or worn, the pump loses hydraulic efficiency and flow rate drops — replacing it with the OEM component restores the designed flow path and pressure output.

Hayward Part Number SPX1425B

Poolaroo Pro Tip

When replacing the top diffuser plate, inspect the full diffuser assembly — impeller, diffuser body, and shaft seal — for wear at the same service interval. Addressing all worn internal components in one service visit prevents repeat pump teardowns and ensures the restored hydraulic path performs as designed. Always confirm the part number against your pump's model label or exploded diagram before ordering, as diffuser plate designs vary across Hayward pump families.
