This type of pump is designed to handle high temperature liquid upto+400°C Especially for hot oil. thermic fluid etc. The pump and motor are connected by an adaptor plate. The adapter is constructed in the middle to separate the motor from the pump thermally by reducing the heat transfer to the motor. In this type of pump, circulation plan to cool the motor and lubricate the bearings is executed by an auxiliary impeller installed on the rotor shaft on the front side independent from the main pump A heat exchanger is provided on the stator body to cool the motor by an external cooling water supply.
