The balanced contact surface design allows the mechanical seal to be used in applications with high pressures without suffering premature wear. Recommended for working with sticky fluids and fluids laden with particles and fibres. Unlike the multispring models, the wave spring model cannot be blocked or obstructed and its open leaf design produces a selfcleaning effect. Standard A9 type fixed stationary part, standardised seal, compliant with EN 12756 (KB).
The casing can incorporate a pumping ring to reduce the temperature between the contact surfaces and facilitate the barrier fluid movement in the case of double mounting (AWS10B-F).
