Marine lubricating oil pumps are essential for ensuring smooth engine operation by circulating oil to reduce friction and wear. These pump systems are designed to handle high-viscosity fluids and operate reliably under harsh marine conditions. They typically include primary, standby, and emergency pumps to maintain continuous lubrication.

Size: Typically ranges from 50 mm to 300 mm in diameter, depending on application.

Grade: ISO VG 68 to VG 1500, with common grades being VG 100, VG 150, and VG 220.

Viscosity: Operates within 32 cSt to 1500 cSt at 40°C, depending on oil type and temperature.

Buoyancy: Not applicable; designed for fixed or submerged installations without buoyancy requirements.

Material: Cast iron, stainless steel (316/304), or bronze for corrosion resistance in marine environments.

Flow Rate: 10 L/min to 1000 L/min, adjustable based on system requirements.

Pressure Rating: 10 bar to 40 bar, suitable for high-pressure lubrication systems.

Temperature Range: -20°C to 120°C, compatible with marine operating conditions.

Drive Type: Electric motor, hydraulic, or mechanical drive, depending on application.

Seals: Nitrile, Viton, or mechanical seals for leak-proof operation.
