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, this week.
It is evident that more integrators of fuel gas supply systems are taking on a progressively substantial role in designing fuel supply systems, especially for LNG-powered vessels. Therefore, they increasingly require critical components specially designed to operate under extremely low temperatures and high pressures. Based on decades of experience in low-pressure fuel and cargo pumps for LNG, we made a strategic decision to extend our scope and include a larger part of the LNG fuel supply system by developing a high-pressure pump unit, exclusively designed for maritime purposes, says Johnny Houmann, CSO in Svanehøj.
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.
