Dosing and transporting a range of fluids using air-operated double diaphragm pumps. This pump works well with both household and commercial cleaning products that contain chloride. For industrial operations and OEM applications with lower flow rates. Reduced start-up pressure is needed for unbalanced spool valve air motors in order to use regulating air pressure to adjust flow more precisely. Pump wetted materials can be used in corrosive situations and are compatible with the savagest fluids. Polypropylene is used to construct the air motor, including the air directional valve and air chamber coverings.
