Reciprocating Pump in Ship

High-Pressure Fuel Supply for Clean-Energy Vessels

 

The marine reciprocating pump is a plunger-type positive displacement pump designed specifically for shipboard LNG, liquid nitrogen, and liquid ammonia fuel supply systems. It handles the high-pressure fuel delivery requirements of marine engines and vaporizer systems while withstanding the confined spaces, motion, vibration, and safety demands of marine service.

The horizontal plunger design is compact and engineered for installation in engine rooms and other confined vessel spaces. The structure is reinforced to maintain stable operation under ship rolling, pitching, and sustained vibration. The plungers and valve assemblies are manufactured from high-strength alloy materials validated for cryogenic and corrosive service, and the specialized sealing system is designed for long-term reliability under continuous shipboard operation.

Flow rates range from 0.4 m³/h upward. Discharge pressures are typically specified from 25 MPa to 45 MPa for marine fuel supply applications. Higher pressures can be evaluated for specific requirements.

Marine Certification

 

The marine reciprocating pump holds CCS type approval, confirming compliance with the safety and performance standards required for shipboard clean-fuel systems. The product supports compliance with IMO Tier III emission regulations for clean-fuel propulsion systems.

Each pump undergoes full performance testing on the company's in-house cryogenic test bench, with test records maintained for ship surveyor review. Third-party inspection and witness testing can be arranged.

The engineering team has extensive experience in marine cryogenic equipment. Lead time from technical approval to delivery is typically 24 to 32 weeks depending on specifications and certification requirements. After delivery, installation guidance, commissioning support, spare parts supply, and remote troubleshooting are available as specified in the contract.
