Features
Dual seal
Available for standard (Cartex-ASDN) and big bore (Cartex-ABDN) seal chambers
Cartridge
Balanced
Independent of direction of rotation
Double pressure balanced
Integrated pumping device
Advantages
Ideal for use in ANSI process pumps
Universal applicable for packings conversions, retrofits or OEM
Ideal seal for standardizations
No dimensional modification of the seal chamber necessary, small radial installation height
No damage of the shaft by dynamically loaded O-Ring
Extended service life
Installation faults are avoided, cost-effective
No damage caused by dirt entered during assembly
Straightforward and easy installation due to pre-assembled unit (reduced down-times)
Recommended applications
Water and waste water technology
Chemical industry
Petrochemical industry
Pharmaceutical industry
Food and beverage industry
