ABSTRACT:
A progressing cavity, positive displacement rotary pump assembly for fluid or semi-fluid material. The assembly includes a rotary shaft with an associated drive motor and pump components including a tubular stator with an interior helical surface and an orbital rotor within the stator operably connected to the shaft and having an exterior helical surface. The helical rotor surface has one more thread than the helical stator surface which it engages, to define sealed pumping cavities that advance axially as the rotor rotates and orbits within the stator. The rotor is coupled to the shaft by a flexible torque tube with one end connected to the shaft and the other connected to an end of the rotor to transmit driving torque to the rotor and to flex sufficiently to accommodate orbital movement of the rotor.
