Abstract:
A pump (10) is disclosed for use in pressurizing a cryogenic fluid. The pump may have a barrel (40), and a boost enclosure (36) disposed around the barrel. The pump may also have a boost plunger (48) disposed inside the barrel and configured to discharge fluid into the boost enclosure. The pump may further have a main plunger (50) disposed inside the barrel and configured to receive fluid from the boost enclosure and to increase a pressure of the fluid.
