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, valve 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.
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.
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.

AIR AND LUBE REQUIREMENTS
WARNING EXCESSIVE AIR PRESSURE. Can cause pump
damage, personal injury or property damage.
FLUID SECTION DISASSEMBLY
S Afiltercapableoffilteringoutparticleslargerthan50micronsshould

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.
1. Remove top manifold(s).
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 (7) diaphragm and
a backup (8) diaphragm. Refer to the auxiliary view in figure 1.
4. Remove the (6) diaphragm washer, (7) or (7 / 8) diaphragms, (5)
backup washer and (196) cushion.
OPERATING INSTRUCTIONS
NOTE: Do not scratch or mar the surface of (1) diaphragm rod.
S Always flush the pump with a solvent compatible with the material
beingpumpedifthematerialbeingpumpedissubjectto“settingup”
when not in use for a period of time.
S Disconnecttheairsupplyfromthepumpifitistobeinactiveforafew
hours.
S Theoutletmaterialvolumeisgovernednotonlybytheairsupplybut

tubing should not be too small or restrictive. Be sure not to use hose
which might collapse.
FLUID SECTION REASSEMBLY
SERVICENOTE:AROpn204214-Tdiaphragmassemblytoolisrecom-
mended for use when reassembling the pump.
S Reassemble in reverse order.
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 Becertainthediaphragmassemblybottomsoutonthe(1)rod, back
off PTFE diaphragm assembly far enough to align holes.
S FormodelswithPTFEdiaphragms:Item(8)Santoprenediaphragm
is installed with the side marked “AIR SIDE” towards the pump cen-
ter body. Install the (7) PTFE diaphragm with the side marked
“FLUID SIDE” towards the fluid cap.
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.

3. Installnew(168)“O”ringsand(169)seal -- Notethelipdirection.Lu-
bricate and replace (167).
4. Reassemble remaining parts, replace (173 and 174) “O” rings.
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 parts as necessary. Look for
deep scratches on metallic 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.
MAJOR VALVE DISASSEMBLY
1. Remove (135) valve block, exposing gaskets (166 and 132) and
(176) checks.
2. Remove (177) snap ring and (107) inlet plug.
3. Onthesideoppositetheairinlet, pushontheinnerdiameterof(111)
spool. Thiswillforcethe(136)pistonplugand(109)pistonout. Con-
tinue pushing the (111) spool and remove. Check for scratches or
gouges.
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.
4. Remove the Major Valve parts (112 - 116).
PILOT VALVE DISASSEMBLY
MAJOR VALVE REASSEMBLY
1. A light tap on (118) should expose the opposite (121) sleeve, (167)
pilot piston and other parts.
1. Replace (112) washer, (114) “O” ring and (113) “O” ring onto (115)
spacer and insert etc. Continue this routine to build the major valve
stack.
2. Remove (170) sleeve and inspect inner bore of sleeve for damage.
NOTE:Becarefultoorientspacerlegsawayfromblockinginternal
ports.
PILOT VALVE REASSEMBLY
2. Replace (111) spool on (136) plug, (110) seal on (109) piston and
replace (109), (136) plug and (177) snap ring.
1. Clean and lubricate parts not being replaced from service kit.
2. Install new (171 and 172) “O” rings, replace (170) sleeve.
V “Smart Parts”, keep these items on hand in addition to the service kits for fast repair and reduction of down time.

TROUBLE SHOOTING
Product discharged from exhaust outlet.
S Check for diaphragm rupture.
S Check tightness of (14) cap 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 fluid caps.
S Check tightness of (14) cap 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.
