Abstract
An electrically motorized coolant pump includes a pump housing, a pump impeller being driven in a pump chamber, two suction-side intake ducts and a pressure-side outflow duct for the coolant. A control actuator that can be hydraulically actuated in response to a demand for coolant is disposed in a housing section of the pump housing between the suction side and the pressure side and the control actuator is coupled to a control element so as to open and close the intake ducts.
