Functional Description

Due to the special fibre compound and the proprietary lubricant mix, the Sealing Compound System DVS is suited to seal stuffing boxes with low pressure. The loose compound will be hold in place by a top and bottom ring, typically made of hydrolysed polyurethane HPU with a special developed geometry. Therefore extrusion of the Sealing compound is prevented and can not cause a premature failure of the DVS Sealing Compound System. Contrary to braided packing the DVS needs little maintenance only. Due to its loose and pliable structure it is absolutely gentle to the shaft or shaft sleeve surface. Preferrably used on worn shafts and in offset or concentric shaft orientations.
