ABSTRACT:
A cryogenic pumping system for pumping a cryogenic fluid generally includes a rotor having a plurality of slots. The rotor includes at least one endring defining a plurality of openings. Each opening is aligned with a different one of the slots. A plurality of rotor bars are each positioned within a different one of the slots. Each rotor bar includes an end portion received within a different one of the openings and welded to the endring. The cryogenic pumping system can be used to pump a cryogenic fluid from a first location to a second location.
