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. 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. This pump is highly chemically compatible.
