How to improve the corrosion resistance of a cast iron pump?

Rovatti cataphoresis treatment is an electrochemical coating process for cast iron components that improves protection from weather conditions, alkali and diluted acids. It is characterized by a high adhesion to the surfaces and uniformity of the coating also in the inner cavities of the component. The result is a black semi-gloss protective layer with homogeneous thickness. Rovatti cataphoresis treatment produces a reduced surface friction in the hydraulic channels improving pump efficiency and increasing driving motor life. Components treated with the Rovatti cataphoresis coating are easily removable during the usual maintenance operations.
