A comparative study of magnetic seals by ferrofluids, magnetorheological fluids and magnetic powders
Frontiers in Materials, 2022 Magnetic seals as a class of non-contact sealing technology have been a research focus. In these seals, magnetic materials, usually ferrofluids or magnetorheological fluids are attracted in sealing gaps as sealing medium. Recently, a novel sealing method

Magnetic Fluid Seal System For Control Of Pump Fugitive Emissions
, 1993 Lecturepg. 3Pump fugitive emissions can now be controlled to near zero levels by the use of a simplified dual seal system. A magnetic fluid secondary seal traps any vapors that leak past the primary mechanical seal.

Interface stability of magnetic fluid seal for sealing liquid
Journal of Physics: Conference Series, 2021 Abstract Theoretically, the velocity distributions of the sealed liquid and magnetic fluid are studied. The velocity of the sealed liquid and magnetic fluid decreases nonlinearly with the increase of the radius. The instability of the interface between magnetic fluid and the sealed liquid is studied.
