Dosing, spraying, transferring, and distributing a wide range of fluids in applications requiring low flow rates are all possible using air-operated double diaphragm pumps. Good for solvents, including most ketones, acetates, aldehydes, aromatic, and chlorinated hydrocarbons, as well as solvent- and water-based gravure, flexo, and paint inks. Pump wetted components can be used in corrosive situations and are compatible with even the most aggressive 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.
