Svanehøj develops marine pump unit for LNG fuel

As demand for LNG-fueled vessels remains high, the marine pump specialist Svanehøj can now offer a high-pressure pump solution for two-stroke engines – a compact unit with three combined cold ends designed for optimal flow and longer service intervals.

High-pressure LNG engines offer lower fuel consumption and significantly reduced methane slips. This is driving a surge in demand for crucial components for LNG high-pressure fuel supply systems, which Svanehøj is now ready to meet.

Drawing from extensive expertise in cryogenic solutions, the Danish marine pump specialist has developed a high-pressure fuel pump unit with a drive system and three combined cold ends designed for optimal flow and longer service intervals. The new solution, called “HPP Triplex Unit”, is pre-launched at Kormarine in Busan, Korea.

Svanehøj has designed the HPP Triplex Unit to meet the maritime industry’s demands for leak-free critical components with a long service life. The cold end includes an innovative low-pressure sealing arrangement that reduces friction, ensuring longer service intervals. To further reduce maintenance costs, Svanehøj has developed a cartridge solution for swift sealing replacement. To ensure high efficiency and low-pressure drop, Svanehøj has also incorporated a new inlet valve design.

As part of its ESG strategy, Svanehøj is committed to directing 95% of its R&D investments at solutions and products that support the energy transition in the hard-to-abate sectors. This includes pumps and equipment for carbon capture, Power-to-X, and LNG. In recent years, Svanehøj has invested significantly in new products and services for the LNG segment, including a new submerged fuel pump, launched in 2022, and the acquisition of the US-based specialist in service and overhaul of LNG pumps, Complete Cryogenic Services (CCS), in 2023.
