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 fluidpressure 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 withthe demand. It willbuild and maintain linepresĆ
sure and will stop cycling once maximum line pressure is reached (disĆ
pensing device closed) and will resume pumping as needed.
