Development of low friction axial face seals

WebExcessive rubbing friction between the rotating seal face and the stationary face must not occur. Friction can quickly wear and deteriorate the seal components, causing rapid and premature failure. Mechanical … WebAxial face seals are custom-molded seals that separate pressure fields in gear pumps and gear motors from each other. They enable the pump to operate at maximum efficiency due to maximum seal tightness and low friction.
