Hayward SPX3021C Impeller - 2-1/2 HP

What This Part Is Used For
The Hayward SPX3021C is a 2-1/2 HP impeller used in compatible Hayward pump models. It mounts directly to the motor shaft inside the wet end and drives water through the circulation system. This is the primary water-moving component in the pump assembly.

Why This Part Matters
If the impeller is worn, cracked, or clogged with debris, flow rate drops and filter pressure changes. That can impact heater performance and overall circulation. Replacing a damaged impeller restores proper hydraulic output and protects the motor from added strain.
