21662663 Bilge Pump | Genuine Volvo Penta Part

🔧 Product Description

A genuine Volvo Penta marine bilge pump designed for reliable water removal in the specified manual or electrical installation.

⚙️ Key Features

• Manual diaphragm pump
• Horizontal installation
• Hose connection: 38mm / 1½ inches
• Maximum manual output: approximately 90L/min
• Large-bore emergency bilge connection

🔌 Function

The pump manually discharges bilge water through the large 38mm hose system.

⚠️ Common Signs of Failure

• Low pumping output
• Diaphragm split or hardened
• Non-return valves fouled
• Handle linkage loose
• Hose or fitting leakage

🛠️ Service Notes

• Mount the pump at the lowest point of the bilge where it will actually pick up, sitting level and secured so it cannot topple or shift at sea, and keep it clear of debris that would jam the impeller
• Take the discharge hose up to a loop above the waterline before it turns down to the outlet so the sea cannot siphon back into the boat, and clamp the hose properly at both ends
• Wire the pump on its own protected circuit with cable sized for the length of the run, and make every connection above the level bilge water can reach, using proper waterproof joints rather than tape
• Test the pump and its float or sensing switch by filling the bilge and watching it lift, run and cut out, and repeat the test at the start of each season
• Treat it as a nuisance-water pump rather than damage control — keep the strainer clear and the bilge dry enough that a new leak would be obvious
