Refer to the model and option chart. ARO pumps feature stall resistant design, modular air motor / fluid sec-tions.Air operated double diaphragm pumps utilize a pressure differen-tial in the air chambers to alternately create suction and a positive fluid pressure in the fluid chambers, valve checks ensure a positive flow of fluid.Pump cycling will begin as air pressure is applied and will continue to pump and keep up with the demand. It will build and maintain line pressure and will stop cycling once maximum line pressure is reached (dispensing device closed) and will resume pumping as needed.AIR AND LUBE REQUIREMENTSWARNING age, personal injury or property damage.A filter capable of filtering out particles larger than 50 microns should be used on the air supply. There is no lubrication re-quired other than the “O” ring lubricant which is applied during assembly or repair.If lubricated air is present, make sure that it is compatible with the “O” rings and seals in the air motor section of the pump.INSTALLATIONVerify correct model / configuration prior to installation.Retorque all external fasteners per specifications prior to start up.Pumps are tested in water at assembly. Flush pump with com-patible fluid prior to installation.When the diaphragm pump is used in a forced-feed (flooded inlet) situation, it is recommended that a “Check Valve” be installed at the air inlet.Material supply tubing should be at least the same diameter as the pump inlet manifold connection.Material supply hose must be reinforced, non-collapsible type compatible with the material being pumped.Piping must be adequately supported. Do not use the pump to support the piping.Use flexible connections (such as hose) at the suction and dis-charge. These connections should not be rigid piped and must be compatible with the material being pumped.Secure the diaphragm pump legs to a suitable surface (level and flat) to ensure against damage by vibration.Pumps that need to be submersed must have both wet and non-wet components compatible with the material being pumped.Submersed pumps must have exhaust pipe above liquid level. Exhaust hose must be conductive and grounded.Flooded suction inlet pressure must not exceed 10 psig (0.69 bar).••••••••••••••OPERATING INSTRUCTIONSAlways flush the pump with a solvent compatible with the material being pumped if the material being pumped is subject to “setting up” when not in use for a period of time.Disconnect the air supply from the pump if it is to be inactive for a few hours.PARTS AND SERVICE KITSRefer to the part views and descriptions as provided on pages 4 through 7 for parts identification and service kit information.Certain ARO “Smart Parts” are indicated which should be avail-able for fast repair and reduction of down time.Service kits are divided to service two separate diaphragm pump functions: 1.
