Title: Compact liquid nitrogen pump

Abstract

The invention provides a cryogenic liquid pump system, having a first end with at least an insulating lid and motor; a second end, wherein the second end is a pump, said pump comprising an impeller; and a gas release plate upstream of the impeller; and a shaft disposed between the first end and the second end, wherein the motor imparts mechanical energy to the pump through the shaft. Also provided is a method for preventing cavitation of a cryogenic liquid in a cryogenic pump, the method having the steps of constantly maintaining pressure on the liquid in the pump and evacuating gas bubbles that form within the pump.
