Abstract
A mechanical seal assembly having multiple compression spring assemblies that are used to bias a stationary seal into sealing engagement with a rotating seal, the springs in the spring assemblies being supported on their internal diameter and having their outside diameter visible for their entire length, each spring assembly further including a releasable, expendable clip that serves to preload the two seal faces against one another, limits relative axial movement between the stationary and rotating seal assemblies, and coaxially aligns the stationary and rotating seal assemblies.
