Abstract: A technique facilitates movement of fluids with reduced component loading by utilizing opposed axial forces. The system for moving fluid may be in the form of a gas compressor, liquid pump, or other device able to pump or otherwise move fluid from one location to another. According to an embodiment, the system includes rotor sections which are combined with pumping features. The rotor sections are disposed radially between corresponding inner and outer stator sections which may be powered to cause relative rotation of inner and outer rotor sections in opposite directions. The rotors and corresponding pumping features are configured to move fluid in opposed axial directions toward an outlet section so as to balance axial forces and thus reduce component loading, e.g. thrust bearing loading.

Abstract: A technique facilitates movement of fluids while reducing axial loading on system components such as thrust bearings. The technique utilizes a system, e.g. a compressor, for moving fluid via counter rotating rotors. By way of example, the rotors may utilize impellers for establishing opposed fluid flows along fluid movement sections. The fluid movement sections may be arranged in a back-to-back configuration such that counter rotation of the rotors causes the impellers to move fluid flows in opposed directions, thus reducing axial loading. The opposed fluid flows ultimately are redirected to an outlet.
