Samoa ¼” AODD Pump, DC20, Conductive Acetal-PTFE-PTFE

Double diaphragm pumps that are air-powered may transport and dose a range of fluids. Good for solvents, including most ketones, acetates, aldehydes, aromatic, and chlorinated hydrocarbons, as well as solvent- and water-based gravure, flexo, and paint inks. For industrial processes with lower flow rates and OEM applications. For finer flow adjustment using regulating air pressure, an unbalanced spool valve air motor needs lower start-up pressure. Materials that are pump wetted can be used in corrosive situations and are compatible with the most hostile fluids. Polypropylene is used to make the air motor's air chamber covers and directional air valve. For use in potentially explosive environments (Ex II2 GD IIB/IIC 95 °C), this model is a fully groundable ATEX-certified pump.
