The circulating liquid of the motor cavity is forced by the auxiliary impeller to realize the lubrication of the bearing and the cooling of the motor. The temperature rise is taken away by an external heat exchanger. The special structure of the Adapter (also known as the "hot screen") can reduce the high temperature liquid in the pump cavity into the motor cavity.
