🔌 Function

The flexible vanes rotate inside the pump chamber to create suction, prime the pump and move fluid from the inlet to the outlet. Correct vane flexibility and hub engagement are essential for reliable flow, pressure and self-priming performance.

Common signs replacement is required:

• Reduced flow or inability to reach normal discharge pressure

• Pump fails to prime or repeatedly loses prime

• Pulsing flow, squealing or unusual pump noise

• Cracked, permanently bent or missing impeller vanes

• Heat damage or a loose, spun or corroded hub

📦 Condition

• Brand-new aftermarket replacement part

• Supplied as a new replacement component

• Supplied in suitable retail or equivalent packaging
