products: Magnetic Fluid Feedthrough

Under the condition of shaft rotation, a magnetic fluid feedthrough provides a hermetic seal against both vacuum and gas.
A magnetic loop consists of the magnet, poles and the shaft. Several stages of liquid "O-ring" are formed by the gathering of the magnetic fluid between the poles and the shaft in the presence of magnetic field. Each stage can sustain a pressure of 0.2kgf/cm2. There are normally 10 to 20 stages in the sealing part of the feedthrough.
