NOTICE Important installation operation or maintenance information Page 2 of 8 66M2X0 XXX C en GENERAL DESCRIPTION The ARO diaphragm pump offers high volume delivery even at low air pressure and a broad range of material compatibility options are available Refer to the model and option chart ARO pumps feature stall resistant design modular air motor fluid sections 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 insure 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 REQUIREMENTS ZAWARNING EXCESSIVE AIR PRESSURE Can cause pump dam age personal injury or property damage e 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 e f lubricated air is present make sure that it is compatible with the O rings and seals in the air motor section of the pump OPERATING INSTRUCTIONS e Always flush the pump with a solvent compatible with the ma teria
