Abstract
A cryogenic submerged multi-stage pump assembly includes a vertically oriented pump shaft. A permanent magnet electrical motor includes a rotor attached to the pump shaft and a stator disposed about the rotor. A first-stage impeller assembly includes a first impeller attached to the pump shaft, the first impeller configured to move a cryogenic fluid from a first impeller inlet to a first impeller outlet when the pump shaft is rotated by the electric motor. A second-stage impeller assembly includes a second impeller attached to the pump shaft, the second impeller configured to move the cryogenic fluid from a first impeller housing to a second impeller inlet and then to a second impeller outlet when the pump shaft is rotated by the electric motor. The first and a second impeller housing are disposed about the first and second impellers and configured to channel the cryogenic fluid.
