GENERAL DESCRIPTION
The ARO diaphragm pump offers high volume delivery even at low
air pressure and a broad range of material compatibility options
are 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 differen-
tial in the air chambers to alternately create suction and a positive
fluid pressure in the fluid chambers, valve checks insure a positive
flow of fluid.
Pump cycling will begin as air pressure is applied and 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.
