GENERAL DESCRIPTION
The ARO Diaphragm Pump offers high volume delivery even at low air
pressure and a broad range of material compatibility options 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 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 presĆ
sure and will stop cycling once maximum line pressure is reached (disĆ
pensing device closed) and will resume pumping as needed.
Models 666056ĆX and 66605HĆX: The Acetal material used in these
pumps contains Stainless Steel fibers. It's conductivity allows it to be
connected to a suitable ground. A ground screw and ground wire kit is
provided for this.
