Description

Available in low- and high-temperature designs, the ECS® is a dry-running seal for emission containment and safety/backup that successfully controls VOC (volatile organic compounds) and VHAP (volatile hazardous air pollutant) emissions. The ECS provides an economical alternative to dual seals with liquid barrier systems. As a self-contained cartridge, the outer ECS is used with either a rotating or stationary John Crane primary seal and will successfully contain any nominal leakage from the primary seal. The seal also acts as a backup providing and additional level of safety during process or system upsets. Features California Residents: PROPOSITION 65 WARNING An effective solution in meeting emission requirements while eliminating the need for liquid barrier systems. Will contain any nominal leakage from the primary seal and act as a backup providing an additional level of safety during process or system upsets. As a self-contained cartridge, the outer ECS can be used with either a rotating or stationary John Crane primary seal of a bellows or pusher design. Available in low- and high-temperature designs. Optimized tribopair ensures long life with low face wear and heat generation. Stationary mounted, uniformly loaded bellows plates produce closely controlled seal face loads for extended and reliable performance. High-temperature version utilizes flexible graphite secondary seals for high-temperature applications. High-temperature variant constructed of Alloy 718 bellows for its high-temperature, high-strength and corrosion-resistance capabilities.
