The Waterway 310-4020 Impeller is a replacement component designed for use with 3 HP HiFlo pool pump models. This impeller converts motor shaft rotation into hydraulic energy, generating the water flow required for efficient circulation and filtration. Engineered for proper fit and dynamically balanced performance, it restores circulation efficiency when replacing a worn, cracked, or damaged impeller in compatible HiFlo pump assemblies.

Product Overview

The Waterway 310-4020 Impeller is a critical wet end component used in 3 HP HiFlo pool pump systems. Installed within the pump housing, the impeller draws water into the inlet and accelerates it outward toward the discharge port, creating the pressure necessary for effective circulation and filtration performance. The correct impeller size and balance are essential for maintaining hydraulic efficiency and minimizing strain on the motor.

Over time, pump impellers may experience wear due to debris ingestion, cavitation, or prolonged exposure to treated water. Replacing the impeller with the correct 3 HP HiFlo assembly restores designed flow characteristics, helps maintain peak pump performance, and supports long-term service life when installed with compatible shaft seals and housing components.
