Marine circulating pumps are essential for seawater and freshwater circulation in ship systems. They ensure efficient cooling, lubrication, and operation of engines and equipment. These pumps are designed for durability, corrosion resistance, and high performance in harsh marine environments.

Size: Typically ranges from 1" to 12" in diameter, depending on application.

Grade: Marine-grade materials compliant with ASTM, ISO, or MIL-SPEC standards.

Viscosity: Suitable for fluids with viscosities up to 1,000 cSt (centistokes).

Buoyancy: Designed to operate in submerged or floating conditions, with corrosion-resistant buoyant materials if required.

Material: Constructed from stainless steel (316L), bronze, or reinforced thermoplastics for seawater resistance.

Flow Rate: Ranges from 10 GPM to 5,000 GPM, depending on pump size and power.

Pressure Rating: Typically 50 to 300 PSI, with high-pressure variants available.

Temperature Range: -20°C to 120°C (-4°F to 248°F), with specialized options for extreme conditions.

Power Source: Electric (AC/DC), hydraulic, or engine-driven, with marine-certified motors.

Seal Type: Mechanical seals or lip seals, often double-sealed for leak prevention.

Mounting: Horizontal or vertical configurations, with flange or threaded connections.

Corrosion Resistance: Coatings or material selection for saltwater and chemical resistance.

Compliance: Meets IMO, SOLAS, and other marine regulatory standards.
