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 andoption chart. ARO pumps feature stall resistant
design, modular air motor / fluid sections.
Air operated double diaphragm pumps utilize a pressure differential in
theairchamberstoalternatelycreatesuctionandpositivefluidpressure
in the fluid chambers, ball checks insure a positive flow of fluid.
Pump cycling will begin as air pressureis applied and it will continue to
pump and keepup with thedemand. It willbuild and maintain linepres-
sure and will stopcycling once maximum line pressure is reached(dis-
pensing device closed) and will resume pumping as needed.
