Ferrotec provides advanced technology solutions that make sealed rotating systems work better, more precisely, and more reliably.
In the 1970s, the engineers at Ferrotec pioneered a revolutionary approach to a common mechanical problem, creating a dynamic, hermetic seal for rotating mechanisms. Using Ferrofluid to create a liquid o-ring around a rotating shaft, we patented the first Ferrofluidic® seals which quickly became the gold standard for demanding precision sealing and rotation applications.
For over forty years, our engineering and manufacturing teams have been busy refining, optimizing, and re-envisioning our designs for an expanding set of application challenges. That’s why the world’s leading manufacturers turn to Ferrotec for their most demanding precision sealing requirements.
We design seals for a broad range of industries, shipping millions of Ferrofluidic seals used in a wide range of equipment worldwide. We continue to expand on our original designs with nearly unlimited sizes, complex process fittings, multiple planes of motion, integrated motors, and even computer-controlled intelligence, enabling sophisticated system operation.
A Ferrofluidic seal, formed by our specially optimized ferrofluid and a simple permanent magnetic circuit, provides a hermetic seal against gas, vapor and other contaminants under both static and dynamic conditions while providing virtually no friction between the rotating and stationary components.
