As the industry leader in Ferrofluid
seals and vacuum rotary feedthroughs, Our products are widely
recognized for quality and performance of the ferrofluid that we use
in our seals. With over thirty years of
experience producing seals for the
world’s most demanding applications, we have been able to optimize our ferrofluid
products for the most intense performance requirements.
Because we produce our own ferrofluid, our products can be optimized to the unique demands of target applications. This enables our
solutions to outperform competitive products in the most demanding, high-precision applications.
A Ferrofluid 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.
The
vacuum rotary feedthroughs utilize multiple rings of ferrofluid
contained in stages formed by grooves machined into either the shaft or
pole pieces. Typically a single stage can sustain a pressure
differential of 0.2 atmospheres (200 mbar). The pressure capacity of the
entire feedthrough is approximately equal to the sum of the pressure
capacities of the individual stages.
