Coupling description
General description
The MINEX®-S is a permanent-magnetic synchronous coupling that trans-mits torque through magnetic forces between the internal and the external rotor.
It ensures a hermetic separation of the drive and the driven side in its main function as sealing element in pumps and agitators. For critical media like aggressive acids etc. it serves as a reliable seal and prevents serious leakages occuring.
On request DUT KOREA can manufacture special customer-specific types of the MINEX®-S in connection with DUT KOREA hydraulic components. Thus existing pumps with a conventional shaft seal can be easily retrofitted with the MINEX®-S.
Function/Design
Torque transmission
The coupling consists of an external and an internal rotor. The external rotor has highquality, permanent magnets of changing polarity on the inner side and the internal rotor has them on the outside. The external rotor is normally fixed on the drive side and the magnets are glued in the keyways. The magnets of the driven-sided internal rotor are cylindrically ground to ensure a minimal air gap and encapsulated through a magnetic cover that is impervious to fluids.
In their non-operative states the north and south poles of the rotors are opposite to each other and the magnetic field is completely symmetric. It is only when the rotors are twisted that the magnetic field lines are moved, hence the torque is transmitted through the air gap. Then there is a synchronous operation under a constant torsion angle.
If the maximum coupling torque and the maximum torsion angle are exceeded, the power transmission is interrupted. Thus the MINEX®-S offers an overload protection function of the drive train. After removing the cause of the overload (e. g. damage to the bearing, blocking of the internal rotor) both rotors can be synchronised again and operation is resumed.
Internal rotor External rotor
Run of flux lines
Sealing function
The main component of the MINEX®-S is the containment shroud that is fixed to the driven-sided power unit and separates internal and external rotor from each other. It ensures a low-vibration torque transmission working without mechanical connection and guarantees a completely leak-proof separation of product and atmosphere. The sealing is achieved with a flat seal or an o-ring, thus eliminating the need to dynamically load the sealing elements.
The containment shroud and internal rotor are generally made from stainless steel 1.4571 or Hastelloy. The magnets of the internal rotor are encapsulated to make them impervious to fluids and thus protected against external influences.
Since the containment shroud is a stationary component with a rotating magnetic field, it causes losses of eddy current. In order to keep these low, the containment shroud is also available in Hastelloy from size 75 upwards ensuring a higher electrical resistance than stainless steel. If eddy current losses can definitely be excluded, alternative materials like PEEK or ceram-ics may be chose.

Explosion-protection useMINEX®-S couplings are suitable for the power transmission in drives that are used in hazardous areas. As a component of the device class II the couplings are assessed and confirmed for the use in explosive areas of category 2G according to the EU standards 94/9/EC (ATEX 95).
Please see our website www.ktr.com for advice, copies of certification and operating/ mounting instructions.
1) Resistances to higher pressures can be realized on request of the customer.2) Alternative materials of stationary cans like oxide ceramics (see page 176) or PEEK are available on request.

Redesigning sets for PUR foaming processesConveying and proportioning the media polyol and isocyanate in the processing plants for PUR, ambient air has to be prevented from penetrating into the process, since otherwise unwanted reactions may be produced.
For a reliable sealing of such drives DUT KOREA offers standard sets for retrofit-ting, among others for axial piston pumps types DUT DMP series, REXROTH A2VK and ROTARY POWER C series offering the following benefits:
● Maintenance-free operation ● Standstill periods are considerably reduced ● No more problems with sealing ● Better efficiency and process safety
The assemblies are available for all motor-pump-combinations and in various materials.
