Permanent Magnetic Couplings - Milestones for Environmental Magnetic Technology
DST Permanent Magnetic Couplings guarantee a contact-free power transmission and total absence of leakage due to the usage of static seals. They have become a cost efficient and wear-free alternative to mechanical seals.
The permanent magnet material Samarium Cobalt is the basis and precondition for all practically proven, compact and powerful DST Permanent Magnetic Couplings.
The Type Examination Certificate according to ATEX II2GcIICTX confirms that all basic safety and health requirements concerning design and production of components for the intended use in hazardous areas are fulfilled.
In the PU industry, the DST-Permanent Magnetic Coupling in connection with a conversion kit as a complete hermetically sealed unit between pump and drive motor is used. The same principle is used for making the agitator mixers in PU machines absolutely gas proof in order to prevent the crystallisation of Isocyanate.
The newly developed SSIC ceramic sleeve bearing, compatible with the DST Standard Permanent Magnetic Coupling, has been extremely well accepted by leading agitator pump manufacturers amongst others. The complete temperature range up to 350
