Marine circulating oil pumps are essential for lubricating and cooling engine components in marine vessels. These pump systems ensure continuous oil flow to prevent overheating and reduce friction in critical machinery. They are designed for durability, efficiency, and reliable operation in harsh marine environments.

Size: Typically ranges from 1" to 12" discharge diameters.

Grade: Marine-grade pumps compliant with ISO 8849, ABS, DNV, or other maritime standards.

Viscosity: Suitable for oils with viscosities ranging from 10 cSt to 680 cSt.

Buoyancy: Not applicable; designed for fixed or submerged installations.

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

Flow Rate: 10 GPM to 5,000 GPM depending on model and application.

Pressure Rating: 50 PSI to 300 PSI, varying by design.

Temperature Range: -20°C to 150°C (-4°F to 302°F).

Drive Type: Electric motor-driven (AC/DC) or engine-driven options.

Seal Type: Mechanical seals or lip seals, often oil-resistant.

Mounting: Horizontal or vertical configurations.

Power Range: 0.5 HP to 500 HP, depending on pump size and duty.

Connection Type: Flanged, threaded, or grooved ends per ANSI/ASME standards.

Protection: IP56 or higher for water and dust resistance.

Lubrication: Oil-lubricated bearings or grease-packed for longevity.
