4 Introduction Using our magnetic coupling means eliminate any possible fluid or gas leakage from an area to another. You can comply with the various regulations designed to protect the environment. (See for example the European IPPC Directive 96/61/C) The magnetic couplings are also maintenance free and therefore it s possible to reduce to zero the costs due to spare parts.

5 Principle of operation The GMDO is a permanent magnet suitable for to transmit torque through to the magnetic field that is established between the inner and outer rotor. The use of magnetic coupling is recommended in applications where it is necessary to hermetically separated two zones in order to prevent fluid or gas leakage from an area to another. The classic example is related to the fluid transfer pumps applications. In this applications the fluid must not come into contact with the external environment. The magnetic coupling prevents also to transmit vibration and axial and radial loads on the drive shaft. External coupling half Internal coupling half The magnetic coupling is a synchronous system therefore : The rpm of the internal half of the coupling is equal to the rpm of the external half of the coupling Pag.3 Documento GMDO rev.1 04/14 the talent s wave

6 Principle of operation The magnetic couplings works by using the power generated by permanent magnets ( made with rare earths ) in order to transfer torque between two shafts not mechanically connected. NO EXTERNAL POWER SUPPLY IS NEEDED ( this are permanent magnets not electro magnets ) The magnets are installed alternating between poles (N - S, S - N) in a side by side and opposing position as seen in the diagram. The magnets support is of ferromagnetic material to aid the channelling of the magnetic field correctly and therefore maximizing the transmittable torque. Main benefits No fluid leakage ( guaranteed benefit ) Maintenance free ( guaranteed benefit ) Vibration reduction ( guaranteed benefit ) It s guaranteed the management of misalignment between shafts It s guaranteed hermetic separation between the two areas It s guaranteed the ability to limit a maximum torque Pag.4 Documento GMDO rev.1 04/14 the talent s wave

8 Performance Part of the electric motor transmitted power is absorbed by the magnetic coupling due to three different reasons : eddy current, magnetic hysteresis and hydrodynamic resistance. Therefore is essential to know the fluid viscosity and the rpm in order to determine the magnetic coupling total efficiency. The below graphs represent the magnetic couplings GMDO compared in different working conditions.

9 High efficiency of the system The eddy current, magnetic hysteresis and hydrodynamic resistance directly act on the magnetic coupling total efficiency. Furthermore generate the overheating of the containment shroud (separator). Our company can offer innovative solutions for contain and even completely eliminate this effects.
