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.
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 dif-
ferential 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 pressure and will stop cycling once maxi-
mum line pressure is reached (dispensing device closed) and
will resume pumping as needed.

Secure the diaphragm pump legs to a suitable surface to
insure against damage by vibration.
MAINTENANCE
AIR AND LUBE REQUIREMENTS
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 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
y
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
y
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.
OPERATING INSTRUCTIONS
Always flush the pump with a solvent compatible with

sary. Look for deep scratches on metallic surfaces, and
nicks or cuts in “O”rings.
y
1. Remove (123) screws, releasing (103) covers, (121) wash-
ers, (118) actuator pins and (167) pilot piston.

center body, securing with (123) screws. NOTE: Tighten
(123) screws to 4 - 6 in. lbs (0.45 - 0.68 Nm).
MAJOR VALVE REASSEMBLY
1. Assemble new (139 and 138) U” cups on (111) spool -
LIPS MUST FACE EACH OTHER.
2. Assemble (137) O”rings to (136) large plug.
3. Assemble (137 and 166) O”rings to (107) small plug.
4. Insert (111) spool into (136) large plug, then insert (136)
large plug into (135) valve block, being sure the (111)
spool is rotated to accept (140) valve insert.

TROUBLE SHOOTING
Pump blows air out main exhaust when stalled on either
stroke.
Product discharged from air exhaust.
Check for diaphragm rupture.
y
y
Check air supply.
Check tightness of (6) diaphragm nut.
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 sized
at least as large as the inlet thread diameter of the pump
for proper flow if high viscosity fluids are being pumped.
Suction hose must be non-collapsible type, capable 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 (6) diaphragm nut.

Pump blows air out main exhaust when stalled on either
stroke.
Check all joints on intake manifolds and suction connec-
tions. These must be airtight.
Inspect the pump for solid objects lodged in the dia-
phragm chamber or the seat area.
Check “U”cups on (111) spool in major valve.
Check (141) valve plate and (140) insert for wear.
Check (169) U”cup on (167) pilot piston.
