S Sparks can ignite flammable material and vapors.
S The pumping system and object being sprayed must be
grounded when it is pumping, flushing, recirculating or spraying flammable materials such as paints, solvents, lacquers,

conducive to spontaneous combustion. Ground the dispensing valve or device, containers, hoses and anyobject to which
material is being pumped.
S Secure pump, connections and all contact points to avoid
vibration and generation of contact or static spark.
S Consult local building codes and electrical codes for specific
grounding requirements.
S Aftergrounding, periodically verify continuity ofelectrical path
to ground. Test with an ohmmeter from each component (e.g.,
hoses, pump, clamps, container, spray gun, etc.) to ground to
insure continuity. O hmmeter should show 0.1 ohms or less.
S Submerse the outlet hose end, dispensing valve or device in
the material being dispensed if possible. (Avoid free streaming
of material being dispensed.)
S Use hoses incorporating a static wire.

GENERAL DESCRIPTION
OPERATING INSTRUCTIONS
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 pressure and will stop cycling once maximum line pressure is reached (dispensing device closed) and will resume pumping as needed.
AIR AND LUBE REQUIREMENTS
WARNING
damage, personal injury or property damage.
EXCESSIVE AIR PRESSURE. Can cause pump
S A filter capable offiltering out particles larger than 50 microns should
be used on the air supply.There is no lubrication required other than
the “O” ring lubricant which is applied during assembly or repair.
S If lubricated air is present, make sure that it is compatible with the
Nitrile seals in the air motor section of the pump.
INSTALLATION
S Verify correct model / configuration prior to installation.
S Retorque all external fasteners per specifications prior to start up.
S Pumps are tested in water at assembly. Flush pump with compatible
fluid prior to installation.
S 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.
S Material supply tubing should be at least the same diameter as the
pump inlet manifold connection.
S Material supply hose must be reinforced, non-collapsible type com-
patible with the material being pumped.
S Piping must be adequately supported. Do not use the pump to sup-
port the piping.
S Use flexible connections (such as hose) at the suction and dis-
charge. These connections should not be rigid piped and must be
compatible with the material being pumped.
S Secure the diaphragm pump legs to a suitable surface (level and
flat) to insure against damage by vibration.
S Pumps that need to be submersed must have both wet and non-wet
components compatible with the material being pumped.
S Submersed pumps must have exhaust pipe above liquid level. Ex-
haust hose must be conductive and grounded.
S Flooded suction inlet pressure must not exceed 10 p.s.i.g. (0.69
bar).
S 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.
S Disconnect the air supply from the pump if it is to be inactive for a few
hours.
PARTS AND SERVICE KITS
Refer to the part views and descriptions as provided on page 4 through 7
for parts identification and Service Kit information.
S Certain ARO “Smart Parts” areindicated which should be available
for fast repair and reduction of down time.
S Service kits are divided to service two separate diaphragm pump
functions:1.AIRSECTION,2.FLUIDSECTION.TheFLUIDSECTION is divided further to matchtypical part MATERIAL OPTIONS.
MAINTENANCE
S Provide a clean work surface to protect sensitive internal moving
parts from contamination from dirt and foreign matter during service
disassembly and reassembly.
S Keep good records of service activity and include pump in preven-
tive maintenance program.
S Before disassembling, empty captured material in the outlet man-
ifold by turning the pump upside down to drain material from the
pump.

AIR MOTOR SECTION SERVICE
Service is divided into two parts - 1. Pilot Valve, 2. Major Valve.
GENERAL REASSEMBLY NOTES:
S Air Motor Section Service is continued from Fluid Section repair.
S Inspect and replace old parts with new partsas necessary. Look for
deep scratches on surfaces, and nicks or cuts in “O” rings.
S Take precautions to prevent cutting “O” rings upon installation.
S Lubricate “O” rings with Lubriplate FML-2 grease.
S Do not over-tighten fasteners, refer to torque specification block on
view.
S Re-torque fasteners following restart.
S SERVICE TOOLS -- To aid in the installation of (168) “O” rings onto
the (167) pilot piston, use tool # 204130-T, available from ARO.
PILOT VALVE DISASSEMBLY
1. A light tap on (118) should expose the opposite (121) sleeve, (167)
pilot piston and other parts.
2. Remove (170) sleeve, inspect inner bore of sleeve for damage.
PILOT VALVE REASSEMBLY
1. Clean and lubricate parts not being replaced from service kit.
2. Install new (171 and 172) “O” rings, replace (170) sleeve.
3. Install new (168) “O” rings and (169) seal - Note the lip direction. Lubricate and replace (167).
4. Reassemble remaining parts, replace (173 and 174) “O” rings.
MAJOR VALVE DISASSEMBLY
1. Remove (135) valve block and (233) adapter plate, exposing (132
and 166) gaskets and (176) checks.
2. Insert a small flat bladescrewdriver into the notch in the side of (135)
valve block and push in ontab to remove (233) adapter plate, releasing (140) valve insert, (141) valve plate, (200) gasket.
3. Remove (136) end cap and (137) gasket, releasing (111) spool.
MAJOR VALVE REASSEMBLY
1. Install new (138 and 139) “U” cups on (111) spool -- LIPS MUST
FACE EACH OTHER.
2. Insert (111) spool into (135) valve block.
3. Install (137) gasket on (136) end cap and assemble end cap to (135)
valve block, securing with (105) screws. NOTE: Tighten (105)
screws to 35 - 40 in. lbs (4.0 - 4.5 Nm).
4. Install (140) valve insert and (141) valve plate into (135) valve block.
NOTE: Assemble (140) valve insert with “dished”side toward (141)
valve plate. Assemble (141) valve plate with part numberidentification toward (140) valve insert.
5. Assemble (200) gasket and (233) adapter plate to (135) valve block.
NOTE: Assemble (233) adapter plate with notched side down.
6. Assemble (132 and 166) gaskets and (176) checks to (101) body.
7. Assemble (135) valve block and components to (101) body, securing with (134) screws. NOTE: Tighten (134) screws to 40 - 50 in. lbs
(4.5 - 5.6 Nm).

TROUBLE SHOOTING
Product discharged from exhaust outlet.
S Check for diaphragm rupture.
S Check tightness of (14) diaphragm screw.
Air bubbles in product discharge.
S Check connections of suction plumbing.
S Check “O” rings between intake manifold and inlet side fluid caps.
S Check tightness of (14) diaphragm screw.
Motor blows air or stalls.
S Check (176) check valve for damage or wear.
S Check for restrictions in valve / exhaust.

Low output volume, erratic flow, or no flow.
S Check air supply.
S Check for plugged outlet hose.
S Check for kinked (restrictive) outlet material hose.
S Check for kinked (restrictive) or collapsed inlet material hose.
S Check for pump cavitation -- suction pipe should be sized at least as
large as the inlet threaddiameter of the pump for proper flowif high
viscosity fluids are being pumped. Suction hosemust be a non-collapsing type, capable of pulling a high vacuum.
S Check all joints on the inlet manifolds and suction connections.
These must be air tight.
S Inspect the pump for solid objects lodged in the diaphragm chamber
or the seat area.
