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: Modular mechanically driven diaphragm pump features are presented herein. Such a diaphragm pump can include a motor, a drive mechanism, and a coupling mounted on a wheeled frame. A diaphragm pump can be mounted to the coupling by forming mechanical static and dynamic connections to brace a housing of the diaphragm pump relative to a drive rod which is moved by the drive mechanism to operate the pump. These mechanical static and dynamic connections can be broken to dismount the pump for replacement or servicing. In some cases, a gas charge can be introduced on the non-working fluid side of the diaphragm to boost performance and/or a dampener can be integrated into the housing of the diaphragm pump and mounted/dismounted with the diaphragm pump.

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.
