Keller Products, Inc. (Lexington, MA) has developed the TKO-10-DP pump/skimmer specifically for dye penetrant applications, which are used to detect cracks, seams, or porosity in the surfaces of the parts. The system pulls the penetrant from the surface of the tank through a floating inlet valve using an air-operated pump, separates the penetrant from the rinse water with a permanent separator element, and returns water to the rinse tank at a high flow rate. According to the company, the TKO-1-1O-DP can reduce waste from the dye penetrant area by 75 percent.
