Features
- Single seal
- Available for standard (Cartex-ASPN)
- and big bore (Cartex-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
- Ideal for use in ANSI process pumps
- Universal applicable for packings conversions, retrofits or original equipment
- 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)
