Floating Seals Design for Differential Pressure Applications

Application of Metal face Floating seals is one of the most significant developments in the disc cutter. This type of Seal uses two metal rings that are loaded axially such that they ride against each other with a film of lubricant between them, creating a dynamic face-seal interface. Each ring, one on the rotating hub, and one on the stationary shaft, is sealed to the mounting gland by a rubber ring (Toric, or o O -ring), which also acts to allow a relatively generous hubto-shaft misalignment tolerance, and as a spring to load one Floating Seals ring against the other.
