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 materialbeing pumpedissubjecttosettingup”  
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 If lubricated air is present, make sure that it is compatible with the  
Nitrile 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, (60) inlet manifold.  
2. Remove (22) balls, (19 and 33) “O” rings (if applicable) and (21)  
seats.  
S Material supply tubing should be at least the same diameter as the  
pump inlet manifold connection.  
3. Remove (15) fluid caps.  
S Material supply hose must be reinforced, non-collapsible type com-  
patible with the material being pumped.  
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.  
S Piping must be adequately supported. Do not use the pump to sup-  
port the piping.  
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 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.  
FLUID SECTION REASSEMBLY  
S Pumpsthat needtobesubmersedmusthavebothwetandnon-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 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 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 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 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.  
2. Insertasmallflatbladescrewdriverintothenotchinthesideof(135)  
valveblockandpushinontabtoremove(233)adapterplate,releas-  
ing (140) valve insert, (141) valve plate, (200) gasket.  
3. Remove (136) end cap and (137) gasket, releasing (111) spool.  
MAJOR VALVE REASSEMBLY  
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.  
S 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)gasketon(136)endcapandassembleendcapto(135)  
valve block, securing with (105) screws. NOTE: Tighten (105)  
screws to 35 - 40 in. lbs (4.0 - 4.5 Nm).  
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 part number identifica-  
tion 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)gasketand(233)adapterplateto(135)valveblock.  
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, secur-  
ing with (134) screws. NOTE: Tighten (134) screws to 40 - 50 in. lbs  
(4.5 - 5.6 Nm).  
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.

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.
