Abstract

An electrically operated displacement pump includes an electric motor having a stator and a rotor. The rotor is connected to the fluid displacer to drive axial reciprocation of the fluid displacer. A controller controls operation of the motor based on an operating state of the motor to control pumping by the displacement pump. The controller is configured to operate the pump in a priming mode, during priming of the pump, and a pumping mode, during pumping of process fluid. The controller causes the fluid displacer to move differently in the priming mode than in the pumping mode.
