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 displacement pump has multiple gas compression stages and serial gas flow through the compression stages. The gas is initially compressed in a first compression stage by a first fluid displacement member. The gas from the first compression stage flows to a second compression stage. The gas in the second compression stage is compressed by a second fluid displacement member and output from the pump.

Abstract: A displacement pump includes an electrically powered drive having a drive housing. The drive is at least partially disposed in the drive housing and is configured to provide reciprocating linear motion to a diaphragm. The diaphragm is captured between an adaptor mountable to the drive housing and a fluid cover. The adaptor includes an inner mounting portion interfacing with the drive housing and an outer mounting portion interfacing with the diaphragm. Multiple adaptors having multiple outer mounting portion diameters can be mounted to the same drive housing. Each of the multiple adaptors have the same inner mounting portion configuration to mount to the same drive housing. The adaptors can FIG. 1B mount to the drive housing in multiple orientations while the fluid cover can mount to the adaptor in a single orientation
