Double balanced dual reverse pressure seal with reinforced sleeve.

Double cartridge mechanical seal with double hydraulic balancing suitable for services with pressurised auxiliary fluid or for auxiliary fluid at atmospheric pressure (see operating limits). Ideal for heavy-duty applications with dangerous liquids, at high temperatures and pressure.

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 and adapts to mixers, dryers, mills and also to assembly directly onto the pump shaft.
