Magnetic coupling is a new kind of coupling, which connects motor and machine by permanent magnetic force.They work in the sealless magnetic drive pumps, which transporting volatile, flammable, explosive and toxic solutions with no leakage.Magneic coupling are widely used in various industries and fields, such as chemical, papermaking, foodstuff, pharmacy, and so on. And sealed magnetic valves are perfect choice for some special industries, such as the petrochemical industry, pharmacy and so on.Used the valve , the medium will be in the absolute sealed situation, and there will not any leakage and pollution. Ichoice company can design and produce different magnetic couplings and sealed magnetic valves according to client's requests. We also produce sintered ndfeb magnets over 1, 000 tons every year. The grade includes n35m-n50m, n35h-n48h, n33sh-n48sh, n28uh-n40uh, n28eh-n35eh, n28ah-n30ah .
