Marine LNG fuel pumps and pump systems are designed to handle liquefied natural gas (LNG) for marine vessels, ensuring efficient and safe fuel transfer. These systems are built to withstand cryogenic temperatures and high pressures, meeting stringent maritime safety standards. They play a critical role in LNG-powered ships, enabling reliable fuel delivery to engines or storage tanks.

Size: Typically ranges from 50 mm to 200 mm in diameter, depending on flow rate requirements.

Grade: Designed for marine applications, compliant with IMO and ISO standards.

Viscosity: Optimized for LNG (liquefied natural gas), which has low viscosity (~0.16 cP at -162°C).

Buoyancy: Constructed with materials ensuring neutral buoyancy in LNG to prevent cavitation.

Material: Stainless steel (316L or 304) or aluminum alloys for cryogenic resistance and corrosion protection.

Flow Rate: Varies from 100 m³/h to 1,500 m³/h, depending on system requirements.

Pressure Rating: Typically 10-40 bar, suitable for LNG fuel supply systems.

Temperature Range: Operates at cryogenic temperatures (-162°C to +50°C).

Sealing: Dual mechanical seals or dry gas seals to prevent leakage.

Drive Type: Electric or hydraulic motor-driven, with explosion-proof certification.

Weight: Varies by size, typically 50 kg to 500 kg.

Certification: Complies with DNV, ABS, LR, and other marine classification societies.
