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.
