The GMDO is a permanent magnetic coupling that transmits torque through magnetic forces between the internal and the external rotor.

It ensures a hermatic separation of the drive and the driven side in its main function as sealing element in pumps and agitators. For critical media like isocyanatepolyol or aggressive acids etc.

It serves as a reliable seal and prevents serious leakages occuring.

It ensures also to avoid vibrations, lateral load and radial loading on the pump shaft.


Why do we use the magnetic coupling?

-The GMDO is a system of transmission of torque without mechanical contact between the two shafts (conduit and conductor)
-When used for the actuation of a pump allows the coupling to isolate completely the drive shaft of the pump via a diaphragm seal (stationary Can)
-In this way it avoids the use of a rotary seal (usually a seal) onto the shaft drag to separate the pumped fluid from the environment and consequent
-Elimination of fluid leaks to the outside
-Elimination of fluid contamination by the external environment
-Elimination of maintenance costs (especially downtime) for replacement preventive or replacement due to breakage
