The pump sound pressure levels published here have been updated to an Equivalent
Continuous Sound Level (L
Aeq
) to meet the intent of ANSI S1.13-1971, CAGI-PNEU-
ROP S5.1 using four microphone locations.
NOTICE: All possible options are shown in the chart, however, certain
combinations may not be recommended, consult a representative or the
factory if you have questions concerning availability.
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 pres-
sure and will stop cycling once maximum line pressure is reached (dis-
pensing device closed) and will resume pumping as needed.
