eCartex Single seals
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
- 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 oC ... 220 oC (-40 oF ... 428 oF)
