A genuine used Volvo Penta raw-water pump for selected MD2030, MD2040, D1-30 and D2-40 marine diesel engines. The flange-mounted F4B-9 pump draws seawater through the inlet strainer and circulates it through the heat exchanger and exhaust system.

⚠️ Common Signs of Failure

• Weak or absent exhaust-water discharge
• Engine overheating under load
• Water leakage from the shaft seal or pump cover
• Impeller blades cracked, missing or permanently bent
• Bearing noise, shaft play or scoring inside the pump body
