EagleBurgmann Cartex-SN Mechanical Seal

Cartex-SN Single seals

•Single seal

•Cartridge

•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

•Ideal seal for  standardizations

•Universal applicable for packings conversions, retrofits or original equipment

•No dimensional modification of the seal chamber (centrifugal pumps) 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)

•Individual adaptation to pump design possible

•Customer specific versions available
