Marine main engine pumps are critical for circulating fuel, lubricating oil, and cooling water to ensure smooth engine operation.

These pump systems include fuel injection pumps, lube oil pumps, and cooling water pumps, each serving a specific function.

They are designed for high efficiency, durability, and reliability to withstand harsh marine conditions.

Size: Varies from 50 mm to 500 mm in diameter, depending on application.

Grade: Typically complies with ISO 5199, API 610, or ABS/Lloyd's Register standards.

Viscosity: Handles fluids with viscosities ranging from 1 cSt to 1000 cSt.

Buoyancy: Not applicable unless specified for submersible or floating pump systems.

Material: Constructed from cast iron, stainless steel (316/304), bronze, or duplex steel for corrosion resistance.

Flow Rate: Ranges from 10 m³/h to 2000 m³/h, depending on engine requirements.

Pressure Rating: Operates between 2 bar and 40 bar, tailored to system demands.

Temperature Range: -20°C to 150°C, suitable for marine environments.

Seal Type: Mechanical seals or gland packing, often double seals for critical applications.

Drive Type: Electric motor, gear-driven, or direct engine coupling.

Lubrication: Oil-lubricated bearings or grease-packed, depending on design.

Mounting: Horizontal or vertical configurations, flange or foot-mounted.

Compatibility: Suitable for seawater, fuel oil, lubricating oil, and cooling water systems.
