OPERATING INSTRUCTIONS
WARNING = Hazards or unsafe practices which
could result in severe personal injury,
death or substantial property damage.
CAUTION = Hazards or unsafe practices which
could result in minor personal injury,
product or property damage.
Always flush the pump with a solvent compatible with
the material being pumped if the material being pumped
is subject to “setting up” when not in use for a period of
time.
Disconnect the air supply from the pump if it is to be in-
active for a few hours.
The outlet material volume is governed not only by the
air supply, but also by the material supply available at the
inlet. The material supply tubing should not be too small
or restrictive. Be sure not to use hose which might col-
lapse.
When the diaphragm pump is used in a forced-feed
(flooded inlet) situation, it is recommended that a “check
valve”be installed at the air inlet.

NOTICE
= Important installation, operation or
maintenance information.
GENERAL DESCRIPTION
The ARO diaphragm pump offers high volume delivery even
at low air pressure and a broad range of material compatibil-
ity 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 dif-
ferential in the air chambers to alternately create suction and
a positive fluid pressure in the fluid chambers, ball checks
insure a positive flow of fluid.
y
y
Secure the diaphragm pump legs to a suitable surface to
insure against damage by vibration.
MAINTENANCE
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 pressure and will stop cycling once maxi-
mum line pressure is reached (dispensing device closed) and
will resume pumping as needed.
Certain ARO “Smart Parts” are indicated which should be
available for fast repair and reduction of down time.
Provide a clean work surface to protect sensitive internal
moving parts from contamination from dirt and foreign
matter during service disassembly and reassembly.
Keep good records of service activity and include the
pump in preventive maintenance program.
Service kits are available to service two separate dia-
phragm pump functions: 1. AIR SECTION, 2. FLUID SEC-
TION. The Fluid Section is divided further to match typical
active Material Options.
y

AIR AND LUBE REQUIREMENTS
WARNING EXCESSIVE AIR PRESSURE. Can cause pump
damage, personal injury or property damage.
A filter capable of filtering out particles larger than 50
microns should be used on the air supply. There is no lu-
brication required other than the “O” ring lubricant which
is applied during assembly or repair.
y
y
Before disassembling, empty captured material in the
outlet manifold by turning the pump upside down to
drain material from the pump.
y
If lubricated air is present, make sure that it is compatible
with the “O” rings and seals in the air motor section of the
pump.

Low output volume.
Check for diaphragm rupture.
Check tightness of (14) bolt.
Check air supply.
y
y
y
Check for plugged outlet hose.
For the pump to prime itself, it must be mounted in the
vertical position so that the balls will check by gravity.
Check for pump cavitation - suction pipe should be
1/2” minimum or larger if high viscosity fluids are being
pumped. Suction hose must be non-collapsible type, ca-
pable of pulling a high vacuum.
Air bubbles in product discharge.
Check connections of suction plumbing.
Check “O”rings between intake manifold and fluid caps.
Check tightness of (14) bolt.
y
y
y
y
Pump blows air out main exhaust when stalled on either
stroke.
Check all joints on the intake manifolds and suction con-
nections. These must be air tight.
Check for sticking or improperly seating check valves.
If pump cycles at a high rate or runs erratically, check (119)
piston “O”rings for wear.
y
Check “U”cups on (111) spool in major valve.
Check (141) valve plate and (140) insert for wear.
Check (103) sleeve and (2) “O” ring on diaphragm con-
necting rod.
