Ferrofluidic rotary feedthroughs
Ferrofluidic Seals and Vacuum Feedthroughs
The Ultimate Rotary Seal
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, they patented the first Ferrofluidic® seals which quickly became the gold standard for demanding precision sealing and rotation applications.
Ferrotec design seals for a broad range of industries, shipping millions of Ferrofluidic seals used in a wide range of equipment worldwide. They continue to expand on their original designs with nearly unlimited sizes, complex process fittings, multiple planes of motion, integrated motors, and even computer-controlled intelligence, enabling sophisticated system operation.
