Magnetic Couplings


Magnetic Couplings

DST permanent magnetic couplings are essential for environmentally friendly drive solutions - our couplings help to prevent leakages!

DST magnetic couplings can be used in various areas: besides the chemical, pharmaceutical and food industry, DST products are applied in biotechnology, industrial furnaces, water management, compressors, measurement and dosing technology, hydraulics or petrochemistry.

In applications with critical, highly toxic or aggressive media, hermetically sealed drives are inevitable. DST permanent magnetic couplings offer a reliable alternative to conventional dynamic seals due to their contactless and leakage-free torque transmission in pumps and agitators. With well over 1,000 magnet configurations, we are able to find the perfect solution for the diverse applications of our customers.

“With our many years of experience in non-contact torque transmission, we are your first port of call for the design and development of customised solutions using magnetic couplings and agitator drives”.
