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
theairchamberstoalternatelycreatesuctionandpositivefluidpressure
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.
S Always flush the pump with a solvent compatible with the material
being pumped ifthe materialbeingpumpedissubjectto“settingup”
when not in use for a period of time.
S Disconnecttheairsupplyfromthepumpifitistobeinactiveforafew
hours.
PARTS AND SERVICE KITS
Refertothepartviewsanddescriptionsasprovidedonpage4through7
for parts identification and Service Kit information.
S Certain ARO “Smart Parts” are indicated 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. AIR SECTION, 2. FLUID SECTION. The FLUID SEC-
TION is divided further to match typical part MATERIAL OPTIONS.
AIR AND LUBE REQUIREMENTS
WARNING EXCESSIVE AIR PRESSURE. Can cause pump
damage, personal injury or property damage.
S Afiltercapableoffilteringoutparticleslargerthan50micronsshould
beusedontheairsupply. Thereisnolubricationrequiredotherthan
the “O” ring lubricant which is applied during assembly or repair.
S Iflubricatedairispresent,makesurethatitiscompatiblewiththe“O”
rings and seals in the air motor section of the pump.
MAINTENANCE
S Provide a clean work surface to protect sensitive internal moving
partsfromcontaminationfromdirtandforeignmatter duringservice
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.
INSTALLATION
S Verify correct model / configuration prior to installation.
S Retorque all external fasteners per specifications prior to start up.
S Pumpsaretestedinwateratassembly. Flushpumpwithcompatible
fluid prior to installation.
FLUID SECTION DISASSEMBLY
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.
1. Remove (61) outlet manifold and (60) inlet manifold.
2. Remove (22) balls, (19) “O” rings (if applicable) and (21) seats.
3. Remove (15) fluid caps.
NOTE: Only PTFE diaphragm models use a primary diaphragm (7) and
a backup diaphragm (8). Refer to the auxiliary view in the Fluid Section
illustration.
4. Remove the (14) screw, (6) diaphragm washer, (7) or (7 / 8) dia-
phragms, and (5) backup washer.
NOTE: Do not scratch or mar the surface of (1) diaphragm rod.
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.
FLUID SECTION REASSEMBLY
S Secure the diaphragm pump legs to a suitable surface (level and
flat) to insure against damage by vibration.
S Reassemble in reverse order. Refer to the torque requirements on
page 5.
S Clean and inspect all parts. Replace worn or damaged parts with
new parts as required.
S Pumpsthatneed to be submersed must havebothwetandnon-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 Lubricate (1) diaphragm rod and (144) “U” cup with LubriplateR
FML-2 grease (94276 grease packet is included in service kit).
S FormodelswithPTFEdiaphragms:Item(8)Santoprenediaphragm
is installed with the side marked “AIR SIDE” towards the pump cen-
ter body. Install the PTFE diaphragm (7) with the side marked
“FLUID SIDE” towards the (15) fluid cap.
S Flooded suction inlet pressure must not exceed 10 p.s.i.g. (0.69
bar).
S Re-check torque settings after pump has been re-started and run a
while.

AIR MOTOR SECTION SERVICE
MAJOR VALVE DISASSEMBLY
Service is divided into two parts - 1. Pilot Valve, 2. Major Valve.
GENERAL REASSEMBLY NOTES:
1. Remove (135) valve block and (233) adapter plate, exposing (132 and
166) gaskets and (176) checks.
S
S
Air Motor Section Service is continued from Fluid Section repair.
Inspect and replace old parts with new parts as necessary. Look for
deep scratches on surfaces, and nicks or cuts in “O” rings.
Take precautions to prevent cutting “O” rings upon installation.
Lubricate “O” rings with Lubriplate FML-2 grease.
2. Insert a small flat blade screwdriver into the notch in the side of (135)
valve block and push in on tab to remove (233) adapter plate, releasing
(140) valve insert, (141) valve plate, (200) gasket.
S
S
S
3. Remove (136) end cap and (137) gasket, releasing (111) spool.
Do not over-tighten fasteners, refer to torque specification block on
view.
MAJOR VALVE REASSEMBLY
S
S
Re-torque fasteners following restart.
1. Install new (138 and 139) “U” cups on (111) spool -- LIPS MUST FACE
EACH OTHER.
2. Insert (111) spool into (135) valve block.
SERVICE TOOLS -- To aid in the installation of (168) “O” rings onto the
(167) pilot piston, use tool # 204130-T, available from ARO.
3. Install (137) gasket on (136) end cap and assemble end cap to (135)
valve block, securing with (107) end plates (where applicable) and
(105) screws.
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 number identification
toward (140) valve insert.
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.
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.
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. Lubri-
cate and replace (167).
4. Reassemble remaining parts, replace (173 and 174) “O” rings.

TROUBLE SHOOTING
Product discharged from exhaust outlet.
S Check for diaphragm rupture.
S Check tightness of (14) diaphragm screw.
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 thread diameter of the pump for proper flow if high
viscosity fluids are being pumped. Suction hose must be a non-col-
lapsing type, capable of pulling a high vacuum.
S Check all joints on the inlet manifolds and suction connections.
These must be air tight.
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.
S Inspectthepumpforsolidobjectslodgedinthediaphragmchamber
or the seat area.
