Operation of Bearings and Pumps at Low Temperatures
Two years ago the Cryogenic Engineering Laboratory of the National Bureau of Standards started a program to study pumping of liquid hydrogen at low heads. The primary application was for a pumping unit to circulate 100 gpm of liquid hydrogen with a pressure drop of 5 psig through the cooling passages of an electromagnet. Preliminary work involved the modification of water pumps for pumping cryogenic fluids and these investigations have been described earlier.1
