mechanical Seal face technology

Mechanical seal face geometry is one of the most critical design elements within a mechanical seal. Seal face properties such as: balance diameter, centroid location, surface area, surface finish, drive mechanism, and face topography can be altered to achieve specific results in a variety of liquids. Seal face topography refers to the alteration of an otherwise flat seal face sealing surface to one with a three dimensional surface. Flowserve Corporation issued the first patent in 2007 for applying micro-topography to mechanical seal faces using an excimer laser.
