Samoa ¼” AODD Pump, DC20, PP-PTFE-PTFE-SS

Double diaphragm air-operated pumps for dosing and transporting a range of fluids. This pump is chemically compatible with a variety of substances. For OEM applications and slower-flowing industrial operations. For finer flow adjustment using regulating air pressure, an unbalanced spool valve air motor needs lower startup pressure. Pump wetted materials are appropriate for usage in corrosive settings and are compatible with the most hostile fluids. Polypropylene is used to make the air motor's directional air valve and air chamber covers.
