Double diaphragm air-operated pumps for transporting and dosing a range of fluids. Excellent for solvent-based flexo and gravure inks, varnishes, and paint (including the majority of ketones, acetates, aldehydes, aromatic, and chlorinated hydrocarbons). This 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. This particular model is an Ex II2 GD IIB/IIC 95 °C certified ATEX pump that is completely groundable.
