Features mechanical seal ecs
- 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.
Features mechanical seal ecs
- 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.
About Mechanical seal type ecs
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.
