GENERAL DESCRIPTION  
MAINTENANCE  
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, flap 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 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.  
FLUID SECTION DISASSEMBLY  
1. Remove (61) top manifold, (60) bottom manifold and (53) manifold  
elbow.  
AIR AND LUBE REQUIREMENTS  
2. Remove the flap valve cartridge / seat assemblies.  
3. Remove (15) fluid caps.  
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 If lubricated air is present, make sure that it is compatible with the  
Nitrile “O” rings in the air motor section of the pump.  
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 (6) diaphragm washer, (7) diaphragm and (5) backup  
washer.  
NOTE: Do not scratch or mar the surface of (1) diaphragm rod.  
FLUID SECTION REASSEMBLY  
OPERATING INSTRUCTIONS  
S Reassemble in reverse order. Refer to the torque requirements on  
page 5.  
S Always flush the pump with a solvent compatible with the material  
beingpumpedifthematerialbeing pumpedissubjectto “settingup”  
when not in use for a period of time.  
S Clean and inspect all parts. Replace worn or damaged parts with  
new parts as required.  
S Disconnecttheairsupplyfromthepumpifitistobeinactiveforafew  
hours.  
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 Theoutletmaterialvolumeisgovernednotonlybytheairsupplybut  
alsobythematerialsupplyavailableattheinlet.Thematerialsupply  
tubing should not be too small or restrictive. Be sure not to use hose  
which might collapse.  
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 Secure the diaphragm pump legs to a suitable surface to insure  
against damage by vibration.  
S Re-check torque settings after pump has been re-started and run a  
while.  
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 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, (232) “O” ring and (176) checks.  
2. Remove (233) adapter plate, releasing (140) valve insert, (141)  
valveplate,(199and200)gasketsand(232,243and244)Orings.  
3. Remove (136) end cap and (137) “O” ring, releasing (111) spool.  
S Air Motor Section Service is continued from Fluid Section repair.  
S Inspect and replace old parts with new parts as 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.  
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) “O” ring on (136) end cap and assemble end cap to  
(135) valve block, securing with (107) end plates and (105) screws.  
4. Install(140)valveinsertand(141)valveplateinto(135)valveblock.  
NOTE: Assemble (140) valve insert with “dished” side toward (141)  
valve plate. Assemble (141) valve plate with 2 identification dots to-  
ward (199 and 200) gaskets.  
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 (232, 243 and 244) “O” rings, (199 and 200) gaskets and  
(233) adapter plate to (135) valve block.  
6. Assemble(132and166)gaskets,(176)checksand(232)Oringto  
(101) body.  
PILOT VALVE REASSEMBLY  
7. Assemble (135) valve block and components to (101) body, secur-  
ing with (134) screws.  
1. Clean and lubricate parts not being replaced from service kit.  
2. Install new (171 and 172) “O” rings, replace (170) sleeve.  
3. Installnew (168) “O” ringsand(169) seal -Note thelip direction. Lu-  
bricate 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 gaskets 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 Inspectthepumpforsolidobjectsloggedinthediaphragmchamber  
or the seat area.
