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.
