Precision face topography improves seal performance
Applied technology can minimize heat generation without sacrificing leakage
Since its introduction almost 100 years ago, the mechanical face seal functions similarly to its original design: two rings mechanically held against each other establish a very restrictive leak path. Advances in technology, design, materials and manufacturing techniques have built greater understanding of seal physics, enabling mechanical seals to be used in a vast array of rotating-equipment environments.
Equipment environments and user demands have evolved requiring the mechanical seal to operate at higher speeds, pressures and temperatures, while also being used in larger sizes and on a greater variety of fluids. These demands pose significant challenges to successful performance. In addition, industries and governmental agencies have tightened requirements for seals to leak less and last longer. The job of a seal designer is not getting easier. Fortunately, our progressive understanding of the mechanics of how seals work has been translated into useful models and analytical tools for the seal designer to help configure a seal that handles the environment into which it will be placed.
