The fresh water pump in a ship is a marine pump designed to supply clean, potable water for drinking, cooking, and sanitation.

It ensures consistent water pressure and flow throughout the vessel's freshwater system.

These pumps are typically centrifugal or reciprocating types, built to withstand marine conditions.

Size: Typically ranges from 50 mm to 300 mm in diameter.

Grade: Marine-grade pumps compliant with ISO 5199 or ABS/DNV standards.

Viscosity: Suitable for fluids with viscosity up to 500 cSt.

Buoyancy: Not applicable; designed for fixed installation.

Material: Cast iron, bronze, stainless steel (316L), or duplex steel for corrosion resistance.

Flow Rate: 10 m³/h to 500 m³/h depending on application.

Pressure Rating: 6 bar to 16 bar.

Temperature Range: -20°C to +120°C.

Power Source: Electric motor (440V, 60Hz) or diesel-driven.

Seal Type: Mechanical seals with carbon/silicon carbide faces.

Mounting: Horizontal or vertical, flange-mounted.

Protection: IP56 or higher for water and dust resistance.

Impeller Type: Closed, semi-open, or open based on fluid type.
