Face Spring Seals
In addition to the array of radial spring seals that Eclipse offers, also available are face seal configurations. Generally speaking, face seals are for non-dynamic applications and wither seal pressure inside a vessel (Internal Face Seal) or keep media out of a vessel (External Face Seal). Some face seals do operate dynamically, but consultation with the factory is highly recommended if a dynamic face seal is required. Internal Face Seals are commonly installed in pressure vessel cover plates and in pipe flange assemblies. External Face Seals are often used in vacuum chambers and as excluders to keep debris out of thrust washer areas.
