Magnetic Rotor
Magnetic couplings and drives

Magnetic coupling is a new generation of coupling, which by using the power generated by permanent magnets to transmit drive torque. It consists of external rotor, internal rotor and isolating cover.


Magnetic coupling was widely used in pump and agitator systems to isolate the electric motor drive from highly toxic and/or aggressive liquids. This has the advantage of removing dynamic seals which have a finite lifetime and are prone to leakage. They replace mechanical seals with a complete and air-tight static permanent seal. Magnetic couplings can also be used as a torque limiter to protect system drive components.

Principles of operation
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 channeling of the magnetic field correctly and therefore maximizing transmittable torque.
Benefits of magnetic couplings

1.No leakage
2.Maintenance free

3. Very high efficiency
4.Vibration reduction
5.Management of misalignment between shafts
6.Hermetic separation between two areas
7.Ability to limit a maximum torque

Areas of application

Magnetic couplings can be used to connect gear pumps, screw pumps, centrifugal pumps etc. with all types of electric motor or gear box.


The ability to hermetically separate two areas while 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 etc.


We can provide a complete service from consult, design to sampling and bulk production.
