The ScoreGuard® Coating Advantage

To accommodate the use of liquid materials that are more abrasive and difficult to spray, Nordson has developed ScoreGuard® coated pump plungers. Nordson plungers provide superior performance and toughness over other coatings used in wear applications.

Twice as hard as conventional hard chrome plating, the metallic silver-colored ScoreGuard coating has excellent corrosion resistance to assure reliable operating performance.

With a two-year warranty, ScoreGuard coating provides maximum pump life for superior durability even with the most demanding coating applications.
