ARO (Ingersoll Rand) 1" Double Diaphragm, Air Operated Pump

ARO® is a manufacturer of fluid management products that are skillfully engineered to deliver performance and serviceability, allowing success to flow freely in their customers’ businesses.  That’s why ARO is fluid intelligence – the smart choice in fluid management products for industrial operations.  With over an 85-year legacy of premier product performance and service excellence, ARO provides fluid management equipment for customers and industries around the globe, including chemical, manufacturing, energy, pharmaceutical, mining and more. 

ARO Air Operated Diaphragm Pumps are ideal for general industrial and OEM installation applications.  They can easily pump from clean, light viscosity fluids to corrosive, abrasive medium viscosity fluids and can transfer large particles without damage.  Due to their pneumatic motor, they could be used in potentially explosive areas.  Most of the ARO Diaphragm Pumps are ATEX Certified (CE Ex11 2GD X).

ARO® Air operated Diaphragm Pumps General Description

            The ARO Diaphragm Pump offers high volume delivery even at low air pressure and a broad range of material compatibility options available.  ARO Pumps feature stall resistant design, modular air motor/fluid sections.  Air operated double diaphragm pumps utilize a pressure differential in the air chambers to alternately create suction and positive fluid pressure in the fluid chambers, ball checks insure a positive flow of fluid.  Pump cycling will begin as air pressure is applied and it 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.

BE SURE YOU KNOW WHAT YOU'RE BUYING!!!!!!  All questions should be asked before buying this item and will be answered to the best of my ability.

This unit seems to have had the model number on the tag altered.  A "J" was added at the beginning of the number, and the "Ball Check and Diaphragm Material" numbers have been stamped over.  These are numbers to indicate different materials used in construction.  It was not done by our employees here, so it does lead to a question or two about whether this unit has been used or not.  For this reason we are listing it as used, even though it appears to be unused, surplus.  Photos of the tag aren't very clear but can be made available upon request.
