Marine drainage pumps are specialized pumps designed to remove excess water from ships and offshore structures. These pump systems ensure efficient water management to maintain vessel stability and safety. They are built to withstand harsh marine environments and handle various types of fluids.

Size: Typically ranges from 1.5" to 12" discharge diameters.

Grade: Constructed to meet ASTM, ABS, DNV, or other marine standards.

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

Buoyancy: Designed to operate in submerged or floating conditions.

Material: Commonly made of cast iron, bronze, stainless steel, or composite materials.

Flow Rate: Varies from 50 GPM to over 5,000 GPM.

Pressure Rating: Typically 150 PSI to 300 PSI.

Temperature Range: -20°C to 120°C (-4°F to 248°F).

Power Source: Electric, hydraulic, or diesel-driven.

Corrosion Resistance: High resistance to saltwater and chemicals.

Seal Type: Mechanical seals or lip seals for leak-proof operation.

Mounting: Fixed or portable configurations.

Certifications: Compliant with SOLAS, IMO, and other maritime regulations.
