Non-leakage pump has two technologies, one is the shield pump; The other is a magnetic pump. Magnetic pump application is very wide, especially suitable for highly toxic, flammable and explosive, high power, high temperature, high pressure and strong corrosion and other harsh fluid transport process. In recent years, its reliability and easy maintenance has gradually been recognized by customers, and users often leave the most difficult application requirements to the magnetic pump.

Therefore, with the increasingly updated user concepts, the magnetic pump itself constantly innovative technology to lead the development of the market, and the main manufacturers in the Chinese market to pay attention to quality and service, more and more new occasions began to choose magnetic pumps. The following is the development trend of the application of magnetic pumps in various processes today:

First, the application of the pharmaceutical production process is different from the domestic proprietary Chinese medicine, foreign pharmaceuticals are chemical reaction synthesis, material temperature quenching and heating, in the process there are many harmful substances need magnetic pump transport. In addition, medicine has high requirements for the material of the pump, and all parts of the flow must meet the food hygiene grade.

Second, the application of high temperature medium process The temperature limit of the current rare earth magnetic material Sm2Co17 has reached 350℃. This is widely used in high temperature applications such as many heat transfer oils and can eliminate complex and expensive cooling and sealing systems and improve reliability.

Third, the application of high pressure system High pressure for mechanical seals is a difficult problem, often under high pressure conditions, the price of mechanical seals is higher than the pump. For the magnetic pump, it is very simple to increase the wall thickness of the isolation cover.

Fourth, the application of corrosive media process sealing corrosion is a big problem, but it can be easily solved with magnetic pumps. For some hydrochloric acid, hydrofluoric acid and other media, fluorine plastic lined magnetic pump can be used. For corrosive and high-temperature media such as acetic acid, Hastelloy can be used. The use of special alloy material is a development trend of magnetic pump.

Fifth, the application of easily solidified medium process For liquids that are easily solidified at room temperature, mechanical sealing or shielding pumps will encounter the problem of both heat preservation and cooling. Magnetic pump does not need to cool, can be made into a double jacket type, with steam insulation, to ensure that the liquid in the pump does not solidify. And can be used with temperature probe.

Sixth, the application of liquid chlorine transport process For this extremely dangerous medium, the magnetic pump has developed secondary sealing technology. If the pump is accidentally damaged, there is a second sealing system to ensure that the medium does not leak. The secondary seal can be magnetic seal or even dry gas seal.
