Hayward SPX3210C Impeller - 1 HP With Screw

What This Part Is Used For
The Hayward SPX3210C is a 1 HP pump impeller supplied with screw. It mounts to the motor shaft inside the pump housing and is responsible for pulling water from the pool and pushing it through the filter, heater, and return lines. This is a core wet end component in the circulation system.

Why This Part Matters
If an impeller is worn, cracked, or mismatched, flow drops and system pressure becomes inconsistent. That can lead to poor filtration, heater pressure switch issues, and weak returns at the pool. Using the correct horsepower-rated impeller keeps the pump operating as intended and prevents motor strain.
