Patent number: 9435383Abstract: A progressing cavity pump system including a rotor and a stator having an inner cavity. The rotor is rotationally disposed inside the inner cavity of the stator such that rotation of the rotor relative to the stator causes material in the inner cavity to be pumped therethrough. The pump system further includes a universal joint directly or indirectly rotationally coupled to the rotor, and a cooling system thermally coupled to the universal joint and configured to cool the universal joint by active heat exchange at a position remote from the universal joint.Type: GrantFiled: September 25, 2012Date of Patent: September 6, 2016Assignee: MOYNO, INC.Inventors: Dale H.

Patent number: 8210827Abstract: A progressing cavity pump system including a feeder assembly including a hopper for receiving material to be pumped therein. The feeder assembly includes an auger housing receiving an auger therein. The auger housing has an underlying portion positioned generally below the hopper and having a radial opening open to the hopper, and an extension portion which is generally radially closed. The extension portion and the underlying portion are of a one-piece, seamless construction. The pump system further includes a progressing cavity pump including a rotor, a stator, an inlet and an outlet. The rotor is rotationally disposed inside the stator such that rotation of the rotor causes material in the pump to be pumped from the inlet toward the outlet, and the inlet is fluidly coupled to the extension portion.Type: GrantFiled: October 30, 2007Date of Patent: July 3, 2012Assignee: Moyno, Inc.Inventors: Dale H.

Patent number: 7607903Abstract: An apparatus for removing a stator tube from a position about a rotor of a progressing cavity pump is provided. The apparatus includes an actuator assembly having a base and a piston which is longitudinally displaceable relative to the base, and a pusher rod. The base of the actuator assembly is removably attachable to a discharge end of the stator tube. The pusher rod is longitudinally releasably attachable to the piston at a plurality of locations along the length of the pusher rod and is located to engage the rotor when the base is coupled to the stator tube. The pusher rod is coupled to the piston and the piston is driven by the actuator assembly. With only slight modifications the apparatus may also be used to install the stator tube on the rotor when operated in a substantially opposite way.Type: GrantFiled: April 29, 2005Date of Patent: October 27, 2009Assignee: Moyno, Inc.Inventor: Michael Duane Amburgey
