ARO 1″ Aro Pro Series Non-Metallic Air Operated Double Diaphragm Pump 6661A3-344-C

The ARO diaphragm pump offers high volume delivery even at low air pressures, easy self priming and the ability to pump various viscosity materials. This ARO 1″ diaphragm pump feature big performance in a compact package. It features flow rates up to 47 GPM (177.9 LPM).

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. Flat 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.
