A ferrofluid mixture for use in a ferrofluid rotary seal includes either (1) a first ferrofluid having a predefined carrier liquid and a second ferrofluid mixed with the first ferrofluid where the second ferrofluid has a predefined carrier liquid that is not identical to the predefined carrier liquid of the first ferrofluid and where the first ferrofluid is at least partially miscible with and chemically compatible with the second ferrofluid, or (2) a first predefined carrier liquid, a second predefined carrier liquid that is not identical to the first carrier liquid but is at least partially miscible and chemically compatible with the second carrier liquid, at least one or more dispersants partially miscible in both carrier liquids, and a plurality of finely divided magnetic particles. |
