Double diaphragm air-operated pumps for transporting and dosing a range of fluids. For OEM applications and slower-flowing industrial operations. Lower start-up pressure is needed for unbalanced spool valve air motors so that finer flow adjustments can be made using regulating air pressure. Pump wetted materials are suited for usage in corrosive situations and are compatible with the most demanding fluids. Polypropylene is used to construct the air motor's directional air valve and air chamber covers.
