Permanent magnetic couplings offer an efficient, leak-proof, cost effective, and more reliable alternative to various conventional sealing methods.
Permanent magnet couplings made from rare‐earth materials such as NdFeB render substantial torque, and are used in numerous applications that cannot be addressed with conventional materials. Moreover, formulas have been developed for designing and optimizing these devices. In this paper, the design formulas are summarized and demonstrated via optimization of practical coupling geometries.
We supply magnetic couplings based on the real power transmission needs of our customers. There is no need to alter your system as the magnetic coupling will be designed to suit your machinery. These magnetic couplings can be used to connect gear pumps , screw pumps, centrifugal pumps, etc. with all types of electric motor or gear box.
» Elimination of fluid leakage from the pump shaft.
» Vibrations are not transmitted to the pump.
» No maintenance required for magnetic couplings.
» Using magnetic couplings allows use of standard pumps without expensive mechanical seals.
» No additional cost for purchasing mechanical seal spare parts and maintenance.
The magnetic coupling works by using the power generated by permanent magnets.
No external power supply is needed.
These are permanent magnets not electro magnets.
» no fluid leakage from pump seals. (depending on application)
» maintenance free.
» vibration reduction.
» management of misalignment between shafts.
» hermetic separation between two areas.
» ability to limit a maximum torque.
Areas of Application.
The ability to hermetically seperate two areas whilst continuing to transmit mechanical power from one to the other makes these couplings ideal for applications where prevention of cross contamination is essential. For instance: hydraulic sectors, dosing systems, compressors, sterilizers, industrial ovens, biotechnology, subsea equipment, pharmaceutical industry, chemical industry, food industry, generators, mixers.
HSMAG compliance (on request) is yet a further advantage for using these excellent power transmission couplings within your system.
The permanent magnet coupling designed to transmit torque using the magnetic field that is established between the inner and outer rotor without mechanical contact between shafts.
The use of Permanent Magnetic Couplings is recommended in applications where it is necessary to hermetically separate two zones in order to prevent fluid or gas leakage from one area to another. The classic example is fluid transfer pump applications. In these applications the fluid must not come into contact with the external environment.
These magnetic couplings also prevent transmission of vibration and axial and radial loads through the drive shaft.
Permanent magnetic synchronous coupling; 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.
Principles of operation.
The Permanent Magnetic Couplings work by using the power generated by permanent magnets. No external power supply is needed. These are permanent magnets not electro magnets.

The magnets are installed alternating between poles in a side by side and opposing position as seen in the diagram. The main body of each coupling half is of ferromagnetic material to aid the channelling of the magnetic field correctly and therefore maximizingtransmittable torque.
