GENERAL DESCRIPTION
MAINTENANCE
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, ball 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.
Certain ARO “Smart Parts” are indicated which should be avail-
able for fast repair and reduction of down time.
Provide a clean work surface to protect sensitive internal mov-
ing parts from contamination from dirt and foreign matter dur-
ing 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 diaphragm
pump functions: 1. AIR SECTION, 2. FLUID SECTION. The Fluid
Section is divided further to match typical part Material Op-
tions.
Before disassembling, emptycaptured material in the outlet
manifold by turning the pump upside down to drain material
from the pump.

DIAPHRAGM PUMP SERVICE
EXCESSIVE AIR PRESSURE. Can cause pump dam-
WARNING
age, personal injury or property damage.
GENERAL SERVICE NOTES:
A filter capable of filtering out particles larger than 50 microns
should be used on the air supply. There is no lubrication re-
quired other than the “O” ring lubricant which is applied during
assembly or repair.
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.
y
y
Inspect and replace old parts with new parts as necessary. Look
for deep scratches on metallic surfaces, and nicks or cuts in “O”
rings.
y
Tools needed to complete disassembly and repair:
y
7/8” wrench, 1/2” socket or wrench, 3/8” socket or wrench,
3/8” Allen wrench, 10 mm Allen wrench, T-10 Torx screw-
driver, torque wrench (measuring inch pounds), “O” ring
pick.
y
OPERATING INSTRUCTIONS
Always flush the pump with a solvent compatible with the ma-
terial 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 inactive
for a few hours.
The outlet material volume is governed not only by the air sup-
ply, 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 collapse.
When the diaphragm pump is used in a forced-feed (flooded
inlet) situation, it is recommended that a “check valve” be in-
stalled at the air inlet.
Secure the diaphragm pump legs to a suitable surface to insure
against damage by vibration.
y
FLUID SECTION DISASSEMBLY
1. Remove (61) top manifold.
2. Remove (19) “O” rings, (21) seats, (12) washers (where appli-
cable) and (22) balls.
y
y
3. Remove (60) bottom manifold.
4. Remove (19) “O” rings, (21) seats, (12) washers (where appli-
cable) and (22) balls.
5. Remove (15) fluid caps.
6. Remove (14) bolt, (6) diaphragm washer, (7) or (7 / 8) dia-
phragms and (5) washer.
7. Remove (1) connecting rod from air motor.
8. Carefully remove remaining (14) bolt, (6) diaphragm washer, (7)
or (7 / 8) diaphragms and (5) washer from (1) connecting rod.
Do not mar surface of connecting rod.
y
y
FLUID SECTION REASSEMBLY
Reassemble in reverse order.
Lubricate (1) connecting rod with Lubriplate® or equivalent “O”
ring lubricant.
y
y
Connecting rod (1) should be installed using 96571 bullet, in-
cluded in service kit.
y
Install (5) washers with i.d. chamfer toward diaphragm.
When replacing PTFE diaphragms, install the 93465 Santo-
prene diaphragm behind the PTFE diaphragm.

y
MAJOR VALVE REASSEMBLY
PILOT VALVE DISASSEMBLY
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.
1. Remove (123) screws, releasing (103) covers, (121) washers,
(118) actuator pins and (167) pilot piston.
2. Remove (170) spool bushing and inspect inner bore of bushing
for damage.
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.
5. Assemble (107) small plug into (135) valve block.
6. Assemble (140) valve insert and (141) valve plate to (135) valve
block. NOTE: Assemble (140) valve insert with “dished” side
toward (141) valve plate. Assemble (141) valve plate with iden-
tification dot toward (132) gasket.
PILOT VALVE REASSEMBLY
1. Clean and lubricate parts not being replaced from service kit.
2. Assemble (171) “O” rings to (170) bushing and assemble bush-
ing into (101) center body.
3. Lubricate and assemble (167) pilot piston assembly into (170)
bushing.
4. Assemble (173 and 174) “O” rings and (121) washers to (103)
covers, then insert (118) actuator pins through assembly.
5. Assemble (144) “U” cups (note the lip direction) and (103) cov-
ers to (101) center body, securing with (123) screws. NOTE:
tighten (123) screws to 4 - 6 in. lbs (0.45 - 0.68 Nm).
7. Assemble (132 and 200) gaskets, (135) valve block and (129)
muffler assembly to (101) center body, securing with (134)
bolts. NOTE: Tighten (134) bolts to 15 - 20 in. lbs (1.7 - 2.3 Nm).

TROUBLE SHOOTING
Product discharged from exhaust outlet.
y
y
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 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 a non-collapsing type, capable of pulling a high
volume.
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
Motor blows air out main exhaust when stalled on either
stroke.
Check all joints on the inlet manifolds and suction connections.
These must be air tight.
Inspect the pump for solid objects lodged in the diaphragm
chamber or the seat area.
y
y
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.
