Features
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
Straightforward and easy installation due to pre-assembled unit
Individual adaptation to pump design possible
Customer specific versions available
