Marine pumps used in ships are designed to handle various fluids like seawater, fuel, oil, and bilge water. They ensure efficient operation of cooling, ballast, firefighting, and cargo systems onboard. Common types include centrifugal, reciprocating, and gear pumps, built to withstand harsh marine conditions.

Size: Typically ranges from 1 inch to 12 inches in diameter, depending on the application.

Grade: Marine-grade pumps, often compliant with ISO 5199 or ANSI/ASME B73.1 standards.

Viscosity: Suitable for fluids with viscosities ranging from 1 cP (water) to 1000 cP (heavy oils).

Buoyancy: Designed to withstand marine conditions, with corrosion-resistant materials to prevent buoyancy issues.

Material: Constructed from stainless steel (316L), bronze, cast iron, or duplex steel for saltwater resistance.

Flow Rate: Varies from 10 GPM to 10,000 GPM, depending on pump type and size.

Pressure Rating: Typically 10 bar to 40 bar, with higher ratings for specialized applications.

Temperature Range: -20°C to 150°C, with some high-temperature models exceeding 200°C.

Drive Type: Electric, hydraulic, or diesel-driven, with IP56 or higher waterproof ratings.

Seal Type: Mechanical seals or gland packing, often with double seals for hazardous fluids.

Applications: Bilge pumping, ballast transfer, fuel oil transfer, cooling water, and firefighting.

Compliance: Meets SOLAS, MARPOL, and IMO regulations for marine safety and environmental standards.
