A review of previous attempts to pump helium as a liquid has recently been summarized by McConnell [1] in which the majority of the pumps tested were centrifugal and intended for “circulation” service, relatively low heads, and moderate flows. Three positive displacement pumps are described, which have been tested in liquid helium service, two of which were reciprocating in nature and utilized a superconducting solenoid submerged in the bath, for low-head, low-flow— 6.3cm3/sec (0.1 gpm)—applications. A reciprocating pump which employed a room-temperature crank arrangement was used to pump nearly 126cm3/sec (2 gpm) of supercritical helium at low differential pressure. None of these units seems to be too well suited for liquid helium transfer in those applications requiring forced convection cooling with subcooled liquid or in applications involving vessel-to-vessel transfers of liquid.
