Hayward SPX3230CU Impeller - 3 HP 5.187in OD

What This Part Is Used For
The Hayward SPX3230CU is a pump impeller listed as 3 HP with a 5.187in OD. It mounts on the motor shaft inside the pump wet end and is the component that moves water through the circulation system. This part is accessed when the pump is opened for rebuild or clog removal.

Why This Part Matters
A damaged or clogged impeller reduces flow, which impacts filtration, heater operation, and cleaner performance. If the wrong impeller is installed, the pump may not match the motor and can run poorly or overload. Replacing the correct impeller restores proper water movement and helps stabilize system performance. This is commonly serviced after debris ingestion, repeated priming issues, or wet end rebuild work.
