A New High-Pressure Reciprocating Cryogenic Pump
Reciprocating positive displacement pumps are distinguished from dynamic (kinetic) and rotary positive displacement types by their ability to pump nonviscous liquids to high pressures in one compression stage, Both reciprocating and rotary positive displacement pumps are further characterized by their given rate of volume flow. The theoretical ability of the reciprocating pump to obtain high pressures in one stage is limited by the effectiveness of the high-pressure seals and, in common with all other types of cryogenic pumps, the control of cavitation is the most important design consideration.
