Type HT high temperature pumps are high temperature pumps suitable up to 400° C. These pumps differ in construction from basic pumps, as pump and motor are separated thermally by an adaptor which prevents heat transfer from the pump to motor area. In these pumps, an independent circulating system using same liquid being pumped with cooling jacket and heat exchanger is provided. The circulation is achieved with the aid of an auxiliary impeller mounted at the fore end of the motor chamber. The cooling arrangement permits the motor and bearings to operate at temperatures much lower than the processed fluid.
