Hayward SPX3220CM Impeller - 2-1/2 HP Max-Rated With Screw

What This Part Is Used For
The Hayward SPX3220CM is a pump impeller listed as 2-1/2 HP max-rated and supplied with a screw as noted. 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 internal service.

Why This Part Matters
A worn or damaged impeller is a common cause of low flow that shows up as weak returns, poor skimming, and heater flow issues. 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 consistent filtration performance. This is often done after debris ingestion, prime issues, or wet end rebuild work.
