Mechanical Seals - Fundamentals

Mechanical seals often have one face of a suitable solid lubricant such that the seal can still operate for a period without the fluid film. In order for mechanical seals perform extended time periods with low surfaces friction, is necessary good maintenance monitoring for hydrodynamic lubrication. This principle is illustrated in the sketch below.
