  • Patent number: 10197048
    Abstract: A tandem motor linear rod pumping apparatus for imparting reciprocating, substantially-vertical motion to a pump rod for a sucker-rod pump. The tandem motor linear rod pumping apparatus includes first and second linear mechanical actuator systems disposed in a single housing. These linear mechanical actuator systems impart and control vertical motion of the pump rod. Each linear mechanical actuator system includes a rack and pinion gearing arrangement. Each rack is operatively connected with two pinions. Each pinion is operatively connected to a motor. Rotation of the two motors in a first direction results in an upward motion of the rack and connected sucker rod pump. Rotation of the two motors in a second direction, opposite the first direction, results in a downward motion of the rack and sucker rod pump. The tandem motor linear rod pumping apparatus includes at least one electronic controller to control the operation of the two motors.

  • Patent number: 10167859
    Abstract: The systems, devices, and methods described herein describe a valve cover assembly that enables the easy removal and insertion of a screw gland into a threaded ring. The valve cover assembly includes an outside housing that provides an offset between a fluid end module and a top end of the valve cover assembly. A spring is positioned between the top end and the threaded ring and biased to provide a downward force on the threaded ring. The screw gland applies a reaction force against a valve plug. A piston is positioned at a base of the threaded ring in contact with the fluid end module. When actuated, the piston overcomes the downward force and lifts the threaded ring from the fluid end module. This reduces the force on the plug and allows a user to remove the screw gland by hand (and install as well) and without additional machinery required.
