Cartex Single Cartridge Plugin Lathing Mechanical Seal

Cartridge Seals, Mechanical Seals, BCARTEX-SNFeatures
• 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
• 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
