Product Overview

The Waterway 310-5140 1.5 HP Impeller Assembly plays a critical role in pump performance by creating the hydraulic force necessary to move water through the circulation system. Installed inside the volute housing, the impeller draws water in through the inlet and accelerates it toward the discharge port. Proper impeller sizing is essential to maintain system efficiency and prevent unnecessary strain on the motor.

Over time, impellers may deteriorate due to debris ingestion, cavitation, or prolonged exposure to treated water. Replacing the impeller with the correct 1.5 HP assembly ensures compatibility with the intended pump configuration and restores consistent water flow. When installed with a compatible shaft seal and housing components, the 310-5140 supports reliable long-term pump operation in residential pool and spa systems.
