Product description

BM (G), BM (GG) series high temperature magnetic drive centrifugal pump is mainly characterized by stable transmission of high temperature medium, usually by the motor, magnetic coupler, cooling device and corrosion resistant centrifugal pump pump head four major parts, magnetic coupler with high temperature resistant rare earth permanent magnet material, can withstand high temperature medium below 350℃ and maintain strong magnetic torque.

A water cooling device is installed between the motor and the magnetic coupler to prevent the heat conduction of the pumped high temperature medium to the motor, so as to maintain the normal operation of the motor, so as to achieve the transmission of high temperature medium without leakage.

The flow parts of the pump can be used according to the needs of 304, 316L, 2205, 904L, TC4, TA1, TA2, C-276, HB2, HB3 and other corrosion resistant materials.

It is widely used in petroleum and petrochemical, fine chemical, pharmaceutical, new energy, new materials, environmental protection, natural gas, power plant, fertilizer, wastewater treatment, ship, nuclear industry and other fields and industrial supporting industries, etc. It is an ideal equipment for conveying high temperature inflammable, explosive, volatile, toxic, rare precious liquid and all kinds of corrosive liquid.

Use environment

High temperature magnetic drive centrifugal pump is dedicated to high temperature hot oil heating occasions or similar heat medium environment, selection of magnetic materials with high magnetic energy product and very low temperature coefficient, high temperature stability and chemical stability, BM(G) series can transport up to 350℃ fluid, BM(GG) series can transport up to 450℃ fluid, BM(GG) series can transport up to 450℃ fluid, It is an ideal high temperature magnetic drive centrifugal pump.
