Marine multistage pumps are high-pressure pumps designed for shipboard use, featuring multiple impellers for efficient fluid transfer. These pump systems are built to handle seawater, fuel, and other liquids in demanding marine environments. They offer durability, corrosion resistance, and reliable performance for critical marine applications.

Marine Multistage Pumps and Pump Systems typically feature the following key specifications and technical properties:

Size: Ranges from 50 mm to 500 mm inlet/outlet diameters, with flow capacities from 10 m³/h to 2000 m³/h.

Grade: Compliant with marine standards such as ABS, DNV, LR, and API 610 for offshore applications.

Viscosity: Suitable for fluids with viscosities up to 500 cSt, depending on pump design.

Buoyancy: Typically not buoyant; designed for fixed installations with corrosion-resistant materials for submerged conditions.

Material: Constructed from cast iron, stainless steel (316/316L), duplex steel, or bronze for seawater and chemical resistance.

Pressure Rating: Operating pressures up to 100 bar, with multistage configurations for high-head applications.

Temperature Range: -20°C to +180°C, depending on material and sealing systems.

Power Source: Electric or hydraulic motor-driven, with power ratings from 5 kW to 500 kW.

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

Mounting: Horizontal or vertical configurations, with flange connections per ANSI/ASME or DIN standards.
