An improved cooling airflow 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 connect to a centrifugal pump impeller at one end of the motor rotor shaft and to an open radial blade blower wheel 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 covers defines an aerothermodynamically matched blower wheel shroud and cooling air inlet and discharge ports for the flow of cooling air across the motor and associated electronic controls. |
