Magnetic drive circulating pump is full-sealed pump,for motor connecting shaft and impeller are separately equipped with magnetic materrials,they attract each other and coupled.It is unneccessary to fit with traditional shaft seal. The rotation torsion of motor drives impeller to the short coming of present customary magnetic drive pump is that rotation is absoutely prohibited under the condition of lacking liquid, otherwise,the machine will be destroyed, resulting in unecessary troubles for customer,"TNT-GROUP" adopts special ceramics as shaft bearing,characterizing strong resistance for abrasion and corrosion.It's advanced performance ensure the safety of quality.
