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 power pumping by the fluid displacer. A cooling circuit extends at least partially about an exterior of a motor housing that houses the electric motor. A fan assembly blows cooling air through the cooling circuit.
