Phosphate Filtration

phosphate dipThis application is a treatment on a steel surface by a chemical solution containing metal phosphate and phosphoric acid as main ingredients to form an adherent corrosion inhibiting layer that serves as a good base for subsequent paint coating.  Phosphate solutions become contaminated over time and require continuous filtration to avoid replacement.  Due to the corrosive nature of the phosphate solution, an enclosed automatic pressure phosphate filter is recommended.  Complete system packages including tanks, pumps, heat exchanger and controls can be proposed.
