eCartex ANSI
Single seals
Features
- Single seal
- Available for standard (eCartex-ASPN) and big bore (eCartex-ABPN) seal chambers
- Cartridge
- Balanced
- Independent of direction of rotation
- Single seals with flush (-ASPN, -ABPN) and with quench combined with lip seal (-ASQN, -ABQN) or throttle ring (-ASTN, -ABTN)
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
