CQB series fluoroplastic magnetic drive pump, magnetic coupling transmission, there is no point of dynamic seal, thus completely eliminate the general shaft type centrifugal pump shaft sealing run, run, drip, leak phenomenon. The over-current components using fluorine plastic and high purity of industrial ceramics, has excellent resistance to corrosion and sealing, so it is widely used in chemical, pharmaceutical, aluminum foil, acid, such as coating, non-ferrous metals industry is volatile and flammable and explosive, and toxic, organic solvents and precious liquids.
