HUNGER DMD2000 V-RING

    DMD2000 V-RING

    The HUNGER DMD Tandem 2000 V-packing System consists of a special U-cup sealing element preceded by pressure reducing low friction wear resistant V-Packings and a support ring to provide the correct system pretension. The combined elements provide low friction stick-slip free movement at both high and low operating speeds.

    The number of V-packings and width of support ring can be varied according to the existing installation groove dimensions.

    The U-cup has an integrated sealing ring made from a low friction and low wear PTFE-Compound which guarantees smooth operation at high operating pressures and stick-slip free movement after long periods of inactivity. In general, packing widths correspond to groove widths. The DMD Tandem 2000 is only suitable for rod sealing in non-adjustable installation grooves.
