Abstract
An electric motor-driven pump, particularly adapted for pumping condensate from refrigeration and air conditioning systems includes a reservoir body, a reservoir cover supporting an electric motor directly connected to a centrifugal pump impeller at one end of the motor rotor shaft and to a centrifugal cooling air fan at the opposite end of the motor rotor shaft. The motor is mounted on the reservoir cover and a motor cover mounted on the reservoir cover defines cooling air inlet and discharge ports for the flow of cooling air propelled by the fan. Efficient cooling air movement is obtained in a mechanically uncomplicated arrangement.
