Permanent magnetic transmission ie. permanent magnetic coupling is the most safety method to machine that   need sealing, to harmful, toxic, pollution, dangerous, pure and valuable products and production process, with a wide range of applications. Petroleum chemical industry, medicine, movies, electroplating, nuclear power industries of liquid mostly have corrosive, inflammable, explosive, toxic, precious, leakage will bring liquid waste and environmental pollution, Vacuum, semiconductor industry needs to prevent external gas intruding, food, medicine need to ensure the purity of medium. Magnetic transmission technology in these areas to find useful. British Howard machinery development Co., LTD. (HMD) devotes itself to manufacture no sealing pump from 1946, from then on, in 37 countries it has sold 70,000 sets and its annual sales of 28 million pounds. An American pharmaceutical factory has hundreds of centrifugal pump with mechanical seal, processing various acids, these pump dry runs due to design problems, can only use 2 ~ 3 months, with a change to ansimag company produced k1516 series magnetic-driving pumps, which is still running from 1993 to 1998 (4.8 hours daily operation 365 days a year). The Midwest, container board factory was disliked the synthesis of rotary vane pump seal of the engineer, said the pump is
