Magnaseal Rotary Motion, or Magnetic fluid (ferrofluid) rotary motion, fills a small annular gap between a rotating shaft and a stationary magnetic pole piece. The gap is part of a high-energy magnetic circuit which includes the shaft and pole piece.
The very large magnetic flux in the gap exerts a force on the fluid, holding it in place against pressure difference from atmosphere to vacuum, yielding a dynamic rotary seal in which there is no solid friction. Therefore, very long operating lifetimes are achieved.
