Abstract
An electric fluid pump and method of regulating flow of liquid therethrough is provided. The pump has an electric motor including a stator and a rotor, wherein the rotor is supported for rotation to drive an impeller that is fixed thereto for rotation to pump coolant from a fluid inlet to a fluid outlet. A controller is in operable, closed loop communication with the electric motor, and the impeller is operable to rotate in a first rotary pumping direction and an opposite second rotary pumping direction in response to a signal from the controller. The first rotary pumping direction produces a first positive flow rate of coolant outwardly from the fluid outlet and the second rotary pumping direction produces a second positive flow rate of coolant outwardly from the fluid outlet, with the first positive flow rate being greater than the second positive flow rate.
