Abstract: An electrically operated displacement pump includes an electric motor having a stator and a rotor. The rotor is connected to the fluid displacement member to drive axial reciprocation of the fluid displacement member. A drive mechanism is disposed between and connected to each of the rotor and the fluid displacement member. The drive mechanism receives a rotational output from the rotor and provides a linear input to the fluid displacement member. A controller controls operation of the motor based on an operating state of the motor to control pumping by the displacement pump.

Abstract: A method of displacing fluid includes pulling a pump displacement member through a suction stroke with a pull, the pull configured to transmit only tensile forces to the fluid displacement member. A working fluid disposed in an internal pressure chamber drive the fluid displacement member through a pumping stroke. The pull is prevented from transmitting any compressive forces to the fluid displacement member, such that the pull does not drive the fluid displacement member through the pumping stroke.

Abstract: A drive system for a pump includes a housing, first and second fluid displacement members, and a reciprocating member configured to mechanically displace the first and second fluid displacement members through respective suction strokes. The housing and fluid displacement members define an internal pressure chamber configured to be filled with a working fluid having a charge pressure. The internal pressure chamber is configured such that the working fluid simultaneously exerts the charge pressure on the first and second fluid displacement members.
