Single cartridge seal with double hydraulic balacing. The seal has a V-ring to contain the continous quench, ideal for pumps with fluids that tend to crystallise on the atmosphere and wich require washing.

Easy installation thanks to the new Fluistrip positioning device and to the flange slots which adapt to different stuffing boxes.

The reinforced sleeve tolerates higher shaft run-out tolerance and adapts to mixers, dryers or mills and also to assembly directly onto the pump shaft.
