Features eCartex ANSI Dual seal

  • Dual seal
  • Available for standard (eCartex-ASDN) and big bore (eCartex-ABDN) seal chambers
  • Cartridge
  • Balanced
  • Independent of direction of rotation
  • Double pressure balanced
  • Integrated pumping device

Advantages eCartex ANSI Dual seal

  • The series has sliding surfaces that are equipped with EagleBurgmann DiamondFace technology as standard
  • Up to 80 % less energy consumption and minimized heat generation of seal due to friction-reducing DiamondFace layer
  • Up to 100 % extended operating period, prolongation of MTBF and MTBR intervals
  • Significantly improved dry-run capability for inadequately lubricated sealing surfaces, thus vastly improved process safety
  • Universally applicable, even with high solids content in the medium
