Marine seawater pumps are robust systems designed to handle corrosive saltwater environments. They are used for cooling, ballast, firefighting, and other marine applications. These pumps ensure reliable operation and durability under harsh sea conditions.

Size: Typically ranges from 1 inch to 24 inches in diameter, depending on flow rate and pressure requirements.

Grade: Marine-grade materials, often compliant with ASTM, ISO, or MIL standards for corrosion resistance.

Viscosity: Designed to handle seawater with viscosity similar to water (1-1.1 cP at 20°C).

Buoyancy: Neutral or slightly positive buoyancy for submerged applications, depending on material density.

Material: Stainless steel (316L), bronze, duplex steel, or non-metallic composites like reinforced thermoplastics.

Flow Rate: 10 GPM to 10,000 GPM, depending on pump type and application.

Pressure Rating: 50 PSI to 1,000 PSI, tailored for deep-sea or surface operations.

Temperature Range: -20°C to 120°C, with variations based on material and sealing.

Seawater Compatibility: Resistant to saltwater corrosion, biofouling, and abrasion.

Drive Type: Electric, hydraulic, or mechanical, with IP68 waterproof ratings for submerged use.

Impeller Type: Closed, open, or semi-open designs for varying solid handling capabilities.

Seal Type: Mechanical seals or lip seals, often with ceramic or tungsten carbide faces.

Weight: Varies from 10 kg to several tons, depending on size and construction.

Power Range: 0.5 kW to 500 kW, based on flow and head requirements.

Mounting: Horizontal, vertical, or submersible configurations.

Standards: Compliance with ABS, DNV, or Lloyds Register for marine applications.
