Marine cryogenic pumps are specialized pumps designed to handle extremely low-temperature fluids like LNG (Liquefied Natural Gas) in marine environments. These pump systems ensure safe and efficient transfer, storage, and transportation of cryogenic liquids aboard ships and offshore facilities. They are built with robust materials and advanced insulation to withstand thermal stress and prevent fluid vaporization.

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

Grade: Designed for marine applications, often meeting ISO 28460 and IGC Code standards.

Viscosity: Suitable for low-viscosity cryogenic fluids like LNG (-162°C).

Buoyancy: Constructed with buoyancy-resistant materials to prevent floatation in cryogenic liquids.

Material: Stainless steel (316L), aluminum alloys, or specialized cryogenic composites.

Flow Rate: Varies from 5 m³/h to 500 m³/h depending on pump type.

Pressure Rating: Typically 10 bar to 40 bar for high-pressure applications.

Sealing: Dual mechanical seals or dry gas seals for leak prevention.

Motor Power: Ranges from 5 kW to 300 kW based on capacity.

Certifications: ABS, DNV, LR, or other marine classification society approvals.
