Hayward SPX3215C Impeller - 1-1/2 HP With Screw

What This Part Is Used For
The Hayward SPX3215C is a pump impeller listed as 1-1/2 HP and supplied with a screw as noted. It mounts on the motor shaft inside the pump wet end and is responsible for moving water through the circulation system. This part is accessed during wet end service, rebuild work, or clog removal.

Why This Part Matters
A damaged or clogged impeller is a common cause of low flow that affects skimming, filtration, heaters, and cleaners. If the wrong impeller is installed, the pump may not match the motor and performance will suffer. Replacing the correct impeller restores proper water movement and more consistent circulation. This is commonly addressed after debris ingestion or during a seal and diffuser service.
