ABSTRACT:
A progressing cavity pump including a drive component configured to be rotated by a motor and a driven component that is magnetically rotationally coupled to the drive component. The driven component is fluidly isolated from the drive component. The pump further includes a wobble stator and a rotor positioned inside the stator and configured such that rotation of the driven component causes relative rotation between the rotor and the stator, which in turn causes material in the pump to be pumped therethrough.
