Gorman-Rupp's Unit 608 Tankleenor provides quick, efficient and economical cleaning of below-ground petroleum storage tanks. Even when tanks are thought to be free of moisture and debris, they often contain enough water and other contaminants to degrade the stored product. Tankleenor can remove contaminants like gel precipitates, microbial growths, rust and water without disturbing the product or taking the tank out of service.
