Cooling system for sanitary pump motor, comprises metallic heat conducting dome fitted over motor box to form cooling chamber which receives air or dielectric oil from motor box through orifices

摘要

The sanitary pump motor operatesa rotary knife (12) and has an output tube (10) and grille (11). A heat conducting metallic dome (2) is fixed (21) to one wall (17) of the motor compartment to form a cooling chamber which receives air or dielectric fluid from the motor compartment through orifices (14,15). The cooling fluid circulates by convection with assistance from an impellor (16).
