Dry Running Design --YTS-1: YongHua''''s YTS-1 has successfully contained emissions and performed as a safety/backup seal in flashing hydrocarbon services and volatile organic compounds. As a result of its dry- running design, it provides a reliable and economical alternative to dual seals with liquid barrier systems. Dry-Running Design Eliminates Liquid Barrier Systems! Through the use of a specially designed bellows assembly and optimal face materials, the YTS-1 has proven itself through years of continuous service as a reliable dry-running seal, eliminating the need for liquid lubrication! As a result, the following are eliminated: . High initial costs of the barrier tank . High initial costs of related system components . Cost of barrier fluid . Cost of cooling water . Cost of long-term maintenance . Seal failures resulting from barrier system operational problems . Hazardous waste disposal issues of contaminated barrier fluid Simple and Versatile Design The YTS-1 is designed as a self-contained cartridge. When used with a standard YongHua primary seal, the YTS-1 requires less axial space than typical dual seal arrangements. The YTS-1 can be used with either a rotating or a stationary primary seal of a bellows or a pusher design.
