Chemical etching is a precise manufacturing process that removes material from a surface to create intricate designs or components. The chemicals used in this process range from relatively mild compounds such as ferric chloride, to highly hazardous substances like hydrofluoric acid and ammonium hydroxide.

Given the potential risks, it is crucial to select a pump that offers excellent chemical resistance and ensures safe containment of the liquid. For such applications, we typically recommend the DB series sealless mag-drive pump series from Finish Thompson. These pumps are available in polypropylene or PVDF, with a variety of o-ring and bushing materials to accommodate nearly all chemical applications.

Finish Thompson mag drive pump model DB11P-6-8P-94 with 2" x 1½" NPT connections close coupled to 1.5 kW 2 pole 400/3/50 IP55 IE3 motor.
