The ARO Diaphragm Pump offers high volume delivery even at low air  
pressures and a broad range of material compatibility options available.  
Refer to the model and option chart. ARO pumps feature stall resis-  
tant design, modular air motor / fluid sections.  
Air operated double diaphragm pumps utilize a pressure differential in  
the air chambers to alternately create suction and positive fluid pres-  
sure in the fluid chambers, ball checks insure a positive flow of fluid.  
Pump cycling will begin as air pressure is applied and it will con-  
tinue to pump and keep up with the demand.

It will build and maintain line pressure and will stop cycling once  
maximum line pressure is reached (dispensing device closed) and  
will resume pumping as needed.

AIR AND LUBE REQUIREMENTS  
FLUID SECTION REASSEMBLY  
WARNING  
EXCESSIVE AIR PRESSURE. Can cause pump  
damage, personal injury or property damage.  
A filter capable of filtering out particles larger than 50  
microns should be used on the air supply. There is no lu-  
brication required other than the “O” ring lubricant which is  
applied during assembly or repair.  
Reassemble in reverse order.  
Clean and inspect all parts. Replace worn or damaged  
parts with new parts as required.  
Lubricate (1) diaphragm rod and (2) “O” ring with  
Key-Lube® grease.  
Use ARO PN / 98930-T Bullet (installation tool) to aid in  
installation of (2) “Oring on (1) diaphragm rod.  
If lubricated air is present, make sure that is compatible  
with the Nitrile “O” rings in the air motor section of the  
pump.  
For 6661XX-XX6-C:  
Attach a regulated airline to the pump inlet; gradually in-  
creasing the air pressure (6-8 p.s.i) to check which side of  
the pump with air blowing out, and then shut down the  
air supplier.  
OPERATING INSTRUCTIONS  
Always flush the pump with a solvent compatible with the  
material being pumped if the material being pumped is  
subject tosetting upwhen not in use for a period of time.  
Disconnect the air supply from the pump if it is to be inactive  
for a few hours.  
The outlet material volume is governed not only by the air  
supply but also by the material supply available at the inlet.  
The material supply tubing should not be too small or restric-  
tive. Be sure not to use hose which might collapse.  
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.  
Fasten (7) diaphragm with (5) washer into (1) diaphragm  
rod, and insert them into (101) Center body from the  
chamber identified with blowing air in the previous step.  
Install (15) fluid cap.  
Thread the other side of (7) diaphragm with (5) washer  
into (1) diaphragm rod, but do not tighten it.  
Record the angle for the misalignment between (7) dia-  
phragm hole and (101) center body holes, then unthread  
the (7) diaphragm and place proper Qty. of (30) shims  
between (5) washer and (1) diaphragm rod.  
Attach a regulated airline to the pump inlet, gradually  
increasing the air pressure (6-8 psi) until the diaphragm  
shift to the other site, shut down the air supply.  
Install the second (15) fluid cap.  
Secure the diaphragm pump legs to a suitable surface to in-  
sure against damage by vibration.  
MAINTENANCE  
Note: for details, refer to service kits manual 48495949.  
For other models:  
Refer to the part views and descriptions as provided on page 4  
through 7 for parts identification and Service Kit information.  
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.  
For models with PTFE diaphragms: Item (8) Santoprene  
diaphragm is installed with the side marked “AIR SIDE” to-  
wards the pump center body. Install the PTFE Diaphragm  
with the side marked “FLUID SIDEtowards the fluid cap.  
Re-check torque settings after pump has been restarted  
and run awhile.  
Certain ARO “Smart Parts” are indicated which should be  
available for fast repair and reduction of down time.  
Service kits are divided to service two separate dia-  
phragm pump functions: 1. AIR SECTION, 2. FLUID SEC-  
TION. The FLUID SECTION is divided further to match  
typical part MATERIAL OPTIONS.  
Provide a clean work surface to protect sensitive internal  
moving parts from contamination from dirt and foreign  
matter during service disassembly and reassembly.  
Keep good records of service activity and include pump  
in preventive maintenance program.

Before disassembling empty captured material in the  
outlet manifold by turning the pump upside down to  
drain material from the pump.

FLUID SECTION DISASSEMBLY  
1. Remove top manifold(s).  
2. Remove (22) balls, (19 and 33) “Orings and (21) seats.  
3. Remove (15) fluid caps.  
CROSS SECTION VIEW OF DIAPHRAGMS  
(Refer to ꢀgure 3, page 5)  
NOTE: Only PTFE diaphragm models use a primary dia-  
phragm (7) and a backup diaphragm (8). Refer to the auxil-  
iary view in the Fluid Section illustration.  
For 6661XX-XX6-C:  
4. Remove (7) diaphragm, (5) washers and (30) shims.

[C] = Carbon Steel [NY] = Nylon  
Air Motor Section Service is continued from Fluid Section  
repair.  
MAJOR VALVE DISASSEMBLY  
Inspect and replace old parts with new parts as neces-  
sary. Look for deep scratches on metallic surfaces, and  
nicks or cuts in “Orings.  
1. Remove (107) plate (or leg depending on model), (108  
and 117) gaskets.  
2. On the side opposite the air inlet, push on the inner di-  
ameter (111) spool. This will force the (109) piston out.  
Continue pushing the (111) spool and remove. Check for  
scratches and gouges.  
3. Reach into the air section (exhaust side) and remove  
(116) spacer, (115) spacers, (113) “O” rings, (114) “O” rings,  
(112) washers, etc. Check for damaged “Orings.  
Take precautions to prevent cutting “O” rings upon instal-  
lation.  
Lubricate “Orings with Key-Lube grease.  
Do not overtighten fasteners, refer to torque specification  
block on view.  
Re-torque fasteners following restart.  
PILOT VALVE DISASSEMBLY  
MAJOR VALVE REASSEMBLY  
1. Remove (104) retaining ring.  
2. Remove (123) screws and (122) “Orings.  
3. Remove (118) piston rod, (121) sleeve bushing, (119) “O”  
rings and (120) spacers from the (101) motor body.  
4. Remove (103) sleeve and (102) “Orings.  
1. Replace (112) washer, (114) “O” ring and (113) “O” ring  
onto (115) spacer and insert etc.  
NOTE: Be careful to orient spacer legs away from  
blocking internal ports.  
2. Lubricate and carefully insert (111) spool.  
3. Install (117) gasket and (107).  
PILOT VALVE REASSEMBLY  
4. Lubricate and install (110) packing cup and insert (109)  
piston into (air inlet side) cavity, the (110) packing cup  
lips should point outward.  
1. Replace two (102) “O” rings if worn or damaged and rein-  
stall (103) sleeve.  
2. Install one of the (121) sleeve bushings, (119) “O” rings,  
(120) spacers and the remaining (121) bushing.  
3. Carefully push (118) pilot rod into bushings etc. and re-  
tain on each end with the two (122) “O” rings, retain with  
(123) screws.  
5. Install (108) gasket and replace (107).  
4. Replace (104) retaining rings.

LUBRICATION / SEALANTS  
Apply Key-Lube to all “O” rings, “U” Cups & mating parts.  
Apply Loctite 271 to threads.  
Apply Dri-Loc 204 to threads.

TROUBLE SHOOTING  
Product discharged from exhaust outlet.  
Low output volume, erratic flow, or no flow.  
Check for diaphragm rupture.  
Check air supply.  
Check tightness of diaphragm nut.  
Check for plugged outlet hose.  
Check for kinked (restrictive) outlet material hose.  
Check for kinked (restrictive) or collapsed inlet  
material hose.  
Air bubbles in product discharge.  
Check connections of suction plumbing.  
Check “Orings between intake manifold and fluid caps.  
Check tightness of diaphragm nut.  
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-collapsing type, capable of  
pulling a high vacuum.  
Check all joints on the inlet manifolds and suction con-  
nections. These must be air tight.  
Inspect the pump for solid objects lodged in the dia-  
phragm chamber or the seat area.
