Double diaphragm air-operated pumps for dosing, spraying, transferring, and spreading a wide range of fluids in applications with modest flow rates. Pump wetted parts are appropriate for use in corrosive situations and are compatible with even the most hostile fluids. Polypropylene is used to construct the air motor's directional air valve and air chamber covers. Acids and alkalis for water treatment as well as CIPs chlorinated cleaning agents for domestic and commercial cleaning procedures are all compatible with this pump.
