The fuel pump in a marine diesel engine delivers pressurized fuel to the injectors for combustion.

Marine pumps handle various fluids like seawater, bilge water, or oil for cooling and lubrication.

Both are critical for efficient engine operation and vessel safety.

Fuel Pump in Marine Diesel Engine:

- Size: Typically 50-500 mm (varies by engine size)

- Grade: API CF-4 or higher (marine-grade diesel)

- Viscosity: 2-6 cSt at 40°C (depends on fuel type)

- Buoyancy: N/A (not applicable for fuel pumps)

- Material: Cast iron, stainless steel, or bronze

- Pressure Range: 3-10 bar (depends on engine requirements)

- Flow Rate: 100-5000 L/hr (engine-dependent)

Marine Pumps (General):

- Size: 25-600 mm (varies by application)

- Grade: Marine-certified (ABS, DNV, etc.)

- Viscosity: 1-1500 cSt (depends on fluid type)

- Buoyancy: N/A (unless submersible)

- Material: Bronze, stainless steel, or composite

- Pressure Range: 1-30 bar (application-specific)

- Flow Rate: 50-20,000 L/min (pump type-dependent)
