Description

Designed to provide rotary motion under high vacuum, these Ferro-Magnetic Fluid Sealed feedthroughs have ConFlat® compatible (CF) mounting flanges. Normal helium leak detectors capable of detecting 1 x 10-11 std cc/sec of Helium flow detect no leakage for CF mounts under static and dynamic testing. Our CF flanged rotary motion feedthroughs routinely operate in the 10-6 Torr range and, when properly prepared and installed, may be used to mid 10-10 Torr using ConFlat compatible (CF) Mounting Flanges. Features Use a special magnetic fluid (ferrofluid) in place of an o-ring seal around dynamic parts Fluid hermetically seals the shaft, making a liquid o-ring while a permanent magnet keeps the fluid in place Ferrofluid magnetically held in stages formed by grooves machined into either the shaft or pole pieces Unlike regular o-rings, the ferrofluid o-ring remains intact for years of operation despite the shaft's motion
