eCartex
Single seals

Features

  • Single seal
  • Cartridge
  • Balanced
  • Independent of direction of rotation
  • Single seals without connections (-SNO), with flush (-SN) and with quench combined with lip seal (-QN) or throttle ring (-TN)
  • Additional variants available for ANSI pumps (e.g. -ABPN) and eccentric screw pumps (-Vario)

Advantages

  • 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

Operating range

Shaft diameter:
d1 = 25 ... 100 mm (1.000" ... 4.000")
Other sizes on request
Temperature:
t= -40 °C ... 220 °C (-40 °F ... 428 °F)
