Permanent Magnet Coupling

Permanent Magnet Coulping

Permanent magnet coupling offers a non-contact transfer of torque, which connects the prime mover(motor) and the working machine through the magnetic force of the permanent magnet.
On this design, no need a direct mechanical connection but use the attraction and repulsion of the magnetic poles to transmit rotational power. To put it simply, it results in a non-contact transmission of mechanical energy.

Function in Mechanical Power Transmission

Operation of magnetic coupling 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.      
For example, fluid transfer pump applications.

Prevent transmission of vibration and axial and radial loads through the drive shaft.

Realize mechanical power transmission between two separate hermetically sealed areas.

Suitable for pplications where prevention of cross contamination is essential:     
• compressors     
• hydraulic sectors     
• dosing systems     
• industrial ovens     
• sterilisers     
• subsea equipment     
• food industry     
• pharmaceutical industry     
• chemical industry     
• generators

Can be designed to suit the specifications of a machinery application.

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

Features

• Available in use of standard pumps without costly mechanical seals.     
• Vibrations are not transmitted to the pump.     
• Elimination of fluid leakage from the pump shaft.     
• No maintenance required for magnetic couplings.     
• No additional cost for purchasing mechanical seal     
• spare parts and maintenance.
