Waterway Plastics 310-4000 Impeller - HiFlo Pump 1 HP

What This Part Is Used For
The Waterway Plastics 310-4000 impeller is used in HiFlo pool and spa pumps equipped with a 1 horsepower motor. It is the primary component responsible for moving water through the pump housing and into the circulation system. This impeller is matched to the HiFlo wet end to maintain proper hydraulic performance. It is typically replaced during pump rebuilds, seal failures, or motor service.

Why This Part Matters
An impeller that is worn, cracked, or mismatched can significantly reduce flow and efficiency. Improper impeller sizing may also place unnecessary load on the motor. Using the correct OEM impeller restores designed flow rates and protects internal components. This helps prevent overheating, cavitation, and premature pump failure.
