Derived from our robust 3-GUPD pump, the MSP-GU is designed to take advantage of years of knowledge and experience in the most rigorous cryogenic high pressure pumping applications, resulting in a marine fuel gas pump built with maximum reliability in mind. Building on the 3-GUPD pump, the MSP-GU pump incorporates many features specific to operation in marine environments. The drive includes robust ductile iron housings and integrated intermediate N2 purge ports for extended cold end life packing life. The cold ends have been specifically designed for marine duty utilizing 316 stainless steel bodies, ASME flanged inlet and outlet ports, and unique internal porting for maximum seal life.
