Magnetic pump: its motor is connected with the external magnetic steel through a magnetic coupling, and the impeller is connected with the internal magnetic steel. Between the outer magnetic steel and the inner magnetic steel is provided with a fully sealed isolation sleeve, the inner and outer magnetic steel are completely separated, so that the inner magnetic steel is in the medium, and the rotating shaft of the motor directly drives the impeller to synchronize rotation through the magnetic pole suction between the magnetic steel. The following is the development trend of the application of magnetic pumps in various processes today:

The application of the first 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 to be transported by magnetic pump. In addition, medicine has high requirements for the material of the pump, and all parts of the flow must meet the food hygiene grade. As a series of international pharmaceutical giants such as Novartis begin to invest in synthetic drug devices in China, the market for magnetic pumps will inevitably be brought.

Second, the application of high temperature medium process The current rare earth magnetic material Sm2Co17 temperature limit has reached 350℃, Shanghai Jiamei magnetic pump factory using special torque ring technology magnetic pump can do 450℃ without any cooling. 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 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.

Fourth, 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. The magnetic pump can handle the system pressure of 350MPa.

Fifth, 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.

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.
