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.
