Magnetic seal driver, mainly composed of permanent magnetic actuator, pump, tank, kettle body and motor, has replaced the mechanical seal which is easy to leak, and has formed a series of products. At present, the maximum working speed can reach more than 6000 rpm, the maximum working pressure can reach 6Mpa, the maximum working temperature can reach 280 ℃, the maximum transmission torque is 2000N · m, and the maximum power of magnetic pump can reach 100kW. Compared with foreign products, it has the advantages of small volume, low energy consumption, high transmission efficiency, stable operation, higher technical level than foreign products, and the price is only less than one third of the imported products. This technology can thoroughly solve the mechanical transmission seal with various leakage problems, is now the most advanced transmission seal technology. The main feature is to use high-intensity magnetic field, through a certain space distance, and through a certain material, to transfer the energy of rotating or translational mechanism. In the process of energy transfer, the integrity of the container is not damaged, and the sealing performance is safe and reliable. The energy transfer is stable and reliable, with high efficiency, without any vibration, electromagnetic and noise pollution. It is a safe and reliable transmission sealing technology. The generation of high-strength magnetic field is based on the use of high-energy permanent magnetic materials. In this technology, rare-earth permanent magnets, the king of permanent magnets in the world, are used as the main raw materials.

China is a big country of rare earth resources in the world, and its reserves account for more than 80% of the proven reserves in the world. The permanent magnetic transmission seal made of rare earth permanent magnets has unique conditions and can effectively promote the development and utilization of rare earth resources in China.
