High-temperature separation type shielded pump

The high-temperature separation type is suitable for transporting high-temperature liquids such as heat transfer oil and hot water. The pump and motor are connected by a connecting body, which can thermally shield the pump and motor to prevent heat transfer. The circulating fluid in the motor cavity is forced to circulate by an auxiliary impeller, achieving lubrication of the bearings and cooling of the motor. The temperature rise is carried away by an external heat exchanger. The special structure of the connecting body (also known as "thermal shield") can prevent the high-temperature liquid in the pump cavity from entering the motor cavity.
