ECS® Metal Bellows Seals | John Crane Mechanical Seals

ECS®

Garniture à soufflet métallique secondaire à fonctionnement à sec pour le confinement des émissions

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.

Caractéristiques

  • 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.
