Waterway .75 HP Center Discharge Pump Impeller (310-5120)

Waterway .75 HP Center Discharge Pump Impeller (310-5120) from Waterway Plastics supports dependable equipment repairs by restoring the connection, flow path, housing interface, or mechanical function the system was designed to use. This pump impellers item is intended for compatible pool, spa, bath, or water equipment applications where precise fit and the correct service configuration matter. This type of replacement is often the cleanest path when the rest of the system is still serviceable but one component has reached the end of its useful life.

As a replacement pump impeller, this part helps restore water movement by replacing the rotating hydraulic component inside a compatible pump wet end. Impellers must be matched carefully because diameter, vane design, horsepower rating, and pump family all affect flow, pressure, and motor load. Key identifiers include the horsepower reference of .75 HP; listed sizing of 75 HP.

Always verify compatibility against the original label, manual, parts diagram, or measurements from the existing installation before beginning the repair. Confirm horsepower rating, pump series, shaft fit, wear ring clearance, and diffuser compatibility before reassembly. If there is any uncertainty, measure the existing part and review any model-specific diagrams before placing the order. Professional installation is recommended for electrical, pressurized, or high-flow systems.
