<p>Lip type rotary seal assemblies are generally discussed herein and particularly those with double directional sealing, wherein the tip of the two sealing lips (26, 28) point in opposite directions. A locking ring (22) is incorporated to retain the seal assembly (10) in the housing. The seal is configure to provide different sealing forces at each end to provide flexibility and enhanced performance where two different conditions on each side of the seal can exist, such as different sealing medium, fluid viscosity, pressure, and rotary speed.</p> |
