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, 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.  
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.  
S Before disassembling, empty captured material in the outlet man-  
ifold by turning the pump upside down to drain material from the  
pump.  
AIR AND LUBE REQUIREMENTS  
WARNING EXCESSIVE AIR PRESSURE. Can cause pump  
damage, personal injury or property damage.  
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.  
FLUID SECTION DISASSEMBLY  
1. Remove top manifold(s).  
2. Remove (22) balls, (19) “O” rings, (21) seats.  
3. Remove (15) fluid caps.  
NOTE:OnlyPTFEdiaphragmmodelsuseaprimarydiaphragm(7)anda  
backup diaphragm (8). Refer to the auxiliary view in the Fluid Section il-  
lustration.  
4. Remove the (6) nut, (7) or (7 / 8) diaphragms and (5) washers.  
5. Remove (3) “O” rings.  
NOTE: Do not scratch or mar the surface of (1) diaphragm rod.  
OPERATING INSTRUCTIONS  
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 Disconnecttheairsupplyfromthepumpifitistobeinactiveforafew  
hours.  
FLUID SECTION REASSEMBLY  
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 Reassemble in reverse order.  
S Clean and inspect all parts. Replace worn or damaged parts with  
new parts as required.  
S Lubricate(1)diaphragmrodand(2)OringwithKey-LubeR grease.  
S UseAROpn/98931-Tbullet(installationtool)toaidininstallationof  
(2) “O” ring on (1) diaphragm rod.  
S Be certain (7) or (7 / 8) diaphragm(s) align properly with (15) fluid  
caps before making final torque adjustments on bolt and nuts to  
avoid twisting the diaphragm.  
S FormodelswithPTFEdiaphragms:Item(8)Santoprenediaphragm  
is installed with the side marked “AIR SIDE” towards the pump cen-  
ter body. Install the PTFE diaphragm with the side marked “FLUID  
SIDE” towards the fluid cap.  
S Re-check torque settings after pump has been re-started and run a  
while.

Product discharged from exhaust outlet.  
S Check for diaphragm rupture.  
S Check tightness of diaphragm nut.  
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.
