Magnetic couplings

We undertake the design and production of special magnetic couplings. Magnetic coupling transfers force between 2 different magnetic fields, which has no physical connection. Magnetic coupling are very useful for vacuum applications, because they do not require direct contact, and using its magnetic fields. Another advantage, magnetic coupling is not being worn out from the same reason. Magnetic mixer is also actually a type of magnetic coupling. Magma can design and manufacture all types of magnetic couplings. Magma also sells quite a few standard magnetic coupling.

Features:

  • Magnetic torque transmission, clean and efficient.
  • Big transmission torque, with small size.
  • Stable properties, wear free, long life time.
  • Magnetic coupling are widely used to solve leakage problems in industrial pumps, reaction kettles, valves, hydraulic cylinders and more.
