High-Temperature Canned Motor Pump

Sinofluid high-temperature canned motor pump is a specially designed, leak-free centrifugal pump developed specifically for handling high-temperature fluids. Its key feature is an integrated, hermetically sealed motor and pump housing, with a built-in shielding sleeve that isolates the motor windings from the process medium—eliminating the need for mechanical seals altogether. This design effectively prevents leakage of even the hottest fluids, making it ideal for applications involving flammable, explosive, toxic, or ultra-pure media.

Product Details

High-Temperature Canned Motor Pump

Structural Characteristics

Shielded Motor
The stator and rotor are both enclosed within a metal shielding sleeve to prevent the medium from leaking into the motor cavity. Motor cooling is achieved either through self-circulation of the medium or via an external cooling system (such as an auxiliary impeller or a cooling water jacket).
High-temperature Resistant Material
✓ Bearings: Made from self-lubricating materials such as silicon carbide and graphite, offering excellent resistance to high-temperature wear.
✓ Pump casing and impeller: Constructed from stainless steel, duplex steel, or high-temperature alloys, designed to withstand harsh, corrosive environments at elevated temperatures.
Thermal Isolation Design
✓ Insulation layer or cooling jacket: Reduces heat transfer to the motor, protecting the winding insulation performance.
✓ High-temperature medium circulation channel: Circulates internally via a pump to dissipate motor heat.
