Abstract
A downhole submersible fluid pump having a progressive cavity motor section driving a rotary pump such as a centrifugal or axial pump. In the motor section the rotor is fixed and by forcing power fluid into the motor chamber around the rotor causes the normally fixed stator to rotate relative to the fixed rotor. This rotary motion is transmitted via the housing to the rotary member of a centrifugal pump drawing fluids from the subterranean formation upwardly as produced fluids.
