Ferrofluidic Seals

For over forty years, we have been supplying dynamic, hermetic seals 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. »

Feedthrough Repair

Ferrotec vacuum feedthroughs are designed to provide most consistent and reliable performance in the most demanding environments. All rotating feedthroughs have finite life and will eventually fail. Most can be overhauled, repaired and refurbished. »

Vacuum Feedthrough Repairs

A Ferrotec seal takes advantage of the response of a magnetic fluid to an applied magnetic field. The basic seal components include ferrofluid, a permanent magnet, two pole pieces and a magnetically permeable shaft. The magnetic circuit, completed by the stationary pole pieces and the rotating shaft, concentrates magnetic flux in the radial gap under each pole piece. When fluid is applied to this gap it assumes the shape of a liquid O-ring and produces a hermetic seal.  »
