Magnetic Couplings Transmit Torque Driving Shaft
HSMAG magnetic couplings transmit torque from the driving shaft to the driven one with magnetic field.

– Design with in-house produced NdFeB or SmCо permanent magnets:
Magnetic field is generated by (NdFeB and SmCo) permanent magnets installed in the driving and driven half- couplings. Protective metal or ceramic containment shroud between the half-couplings ensures tightness of the pumped product. For application at temperatures of the pumped liquid up to 150 ° C neodymium magnets are used, up to 350 ° C – samarium-cobalt magnets. The use of high-coercivity permanent magnets provides compact couplings and high torque values in limited space.

– No leaks, contamination and maintenance:
HSMAG  couplings ensure completely hermetic solution for pumping equipment, eliminating any leaks and keeping the pumped product clean unlike mechanical seals. Application of magnetic couplings provides reduction of costs for maintenance, besides, such couplings do not consume any power for operation.

All manufactured shrouds for couplings undergo thorough quality control test with final pressure test exceeding the operating pressure by 25% to identify defects and ensure stable operation of products under load.

– Ideal for application in explosive media:
The production process is organized using ISO 9001-2015 quality management standards.

– Since 2001 HSMAG  has been providing services of repair of magnetic couplings, replacement and retrofitting of permanent magnet systems, restoring tightness o couplings and retrofitting couplings of foreign and Russian production.

Magnetic Co-Axial Type Coupling
The co-axial coupling consists of three parts, the inner hub, the outer hub, and the optional containment barrier. Both the inner and outer hubs consist of a series of rare earth magnets that are ground, potted, and glued to steel hubs. The inner hub is then completely sealed in stainless steel to protect the magnets and hub from damage or corrosive substances.

Disc vs. Co-Axial Coupling Comparison
Coupling Style
Axial Forces
High axial force which must be restrained
Coupling finds its own center with ~0 axial force
Slip Torque Adjustment
Air gap can be adjusted to increase or decrease slip torque
Coupling hubs can be seperated axially to decrease slip torque (axial force will result)
Angular Misalignment Capacity 3° Max
Ensure coupling hubs (or barrier if used) do not contact
Parallel Misalignment Capacity Magnetic Shaft Couplings for Driving Gear 0.25″ Max
Ensure coupling hubs (or barrier if used) do not contact
Containment Barrier
Simple flat barrier Magnetic Couplings Transmit Torque Driving Shaft
