Our magnetic fluid feedthroughs take 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.
