A magnetic coupling is a system that transfers torque from one shaft to another using a magnetic field rather than a physical mechanical connection.Magnetic couplings are the most of the times used in pumps and propeller systems. This way a static physical barrier can be placed between two zones to separate the fluid from the air ( we can thus separate the wet area of the equipment from the dry area ). By using a Magnetic couplings allows You to remove the dynamic seals from Your system , which could eventually wear out and fail from the sliding of two surfaces against each another.
PERMANENT MAGNETIC COUPLING SOLUTION BY METAU ENGINEERING SRL
The GME is a permanent magnetic coupling that drives torque through magnetic forces between the internal and the external rotor.
That ensures a hermetic separation between the drive and the driven side in its main function as sealing element in pumps and agitators. Recommended for critical fluid or gas like isocyanate, polyol or aggressive acids etc.
It serves as a reliable seal and prevents serious leakages occurring.
Why do we use the magnetic coupling?
-The GME 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 dynamic rotary 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.
