YALAN Dry Gas Seals

DGS (Dry Gas Seals) are the perks of the mechanical seal industry. Dry gas seals are non-contacting, dry-running mechanical face seals that consist of a mating (rotating) ring and a primary (stationary) ring. When operating, lifting geometry in the rotating ring generates a fluid-dynamic lifting force causing the stationary ring to separate and create a gap between the two rings. YALAN Seals Team has been spending great resources in developing and producing DGS (dry gas seals) in the last 3 years, and sccessfully developed and delivered full series of dry gas seals for compressors, pumps and mixers to our overseas clients. YALAN Seals now has a full sets of equipment for producing DGS, from face rings with dynamic pressure grooves to all metal parts and secondary barrier seals, and also built up a testing lab that could handle static and dynamic tests of 6 sets of DGS simultaneously.
