LNG TRANSFER PUMPS: IMPROVING OPERATION - HIGH SUCTION PERFORMANCE PUMP INDUCERS CAN ELIMINATE CAVITATION

摘要

High suction performance pump inducers are critical to a number of industrial and aerospace applications where the required pump inlet pressure is near the vapor pressure of the liquid to be pumped. These include boiler feed pumps, aircraft fuel pumps, space vehicle propellant pumps and liquefied natural gas (LNG) transfer pumps. Moving natural gas efficiently from production sites to where it is used, for instance, requires LNG transfer pumps that can drain more LNG from storage tanks. In space applications, high suction performance inducers can reduce launch costs through lower propellant tank weight, and increased propellant feed system stability and robustness.
