Features:
- Dual seal
- Cartridge
- Balanced
- Independent of direction of rotation
- Double pressure balanced
- Integrated pumping device
- Variants available: for eccentric screw pumps (-Vario) and
gas-lubricated version (-GSDN)
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
Recommended applications:
- Petrochemical industry
- Chemical industry
- Pharmaceutical industry
- Power plant technology
- Pulp and paper industry
- Mining industry
- Food and beverage industry
- Sugar industry Universally applicable
- Centrifugal pumps
- Eccentric screw pumps
Recommended piping plans:
The EagleBurgmann QFT1000 buffer system and QFT2000 vessels are
suitable for eCartex-DN in back-to-back arrangement. The
EagleBurgmann TS1016 and TS2000 thermosiphon systems support double
and back-to-back seal configurations.
