• Always compare the removed impeller or pump against the listed dimensions, drive style, material and housing depth before installation.

🔌 Function

The flexible vanes form expanding chambers on the inlet side and contracting chambers on the discharge side. This produces self-priming suction and moves cooling water or other compatible fluids through the pump.

⚠️ Common Signs of Failure

• Reduced flow or inability to prime
• Engine overheating or weak cooling-water discharge
• Pulsing flow, cavitation or unusual pump noise
• Vanes are cracked, hardened, flattened or missing
• Hub has slipped, corroded or loosened from the rubber body
• Impeller has been damaged by dry running, debris or incompatible fluid
