Separation Seal (Contacting Technology)
The Type 83 is a dual-segmented carbon bushing assembly designed to prevent the migration of bearing oil to the dry gas seal cartridge. Normally applied as a double arrangement with an inert buffer gas. When used in conjunction with the Type 28 dry-running gas seal, it provides a total sealing system that ensures separation of bearing oil and process gas in compressors.
