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.  
Refer to the part views and descriptions as provided on pages 4 through  
7 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.  
Air operated double diaphragm pumps utilize a pressure differential in  
the air chambers to alternately create suction and positive fluid pressure  
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
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.  
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 preven-  
tive maintenance program.  
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.  
FLUID SECTION DISASSEMBLY  
S
S
A filter capable of filtering out particles larger than 50 microns should  
be used on the air supply. There is no lubrication required other than  
the ꢀO" ring lubricant which is applied during assembly or repair.  
If lubricated air is present, make sure that it is compatible with the ꢀO"  
rings and seals in the air motor section of the pump.  
1. Remove top manifold(s).  
2. Remove (22) balls, (19) ꢀO" rings and (21) seats.  
3. Remove (15) fluid caps.  
NOTE: Only Teflon diaphragm models use a primary diaphragm (7) and  
a backup diaphragm (8). Refer to the auxiliary view in the Fluid Section  
illustration.  
OPERATING INSTRUCTIONS  
4. Remove the (14) screws, (6) washers, (7) or (7 / 8) diaphragms and  
(5) washers.  
5. Remove (3) ꢀO" rings.  
S
Always flush the pump with a solvent compatible with the material  
being pumped if the material being pumped is subject to ꢀsetting up"  
when 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 restrictive. 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.  
NOTE: Do not scratch or mar the surface of (1) diaphragm rod.  
S
S
FLUID SECTION REASSEMBLY  
S
S
Reassemble in reverse order.  
Clean and inspect all parts. Replace worn or damaged parts with  
new parts as required.  
S
S
S
S
Lubricate (1) diaphragm rod and (2) ꢀO" ring with Key-LubeR grease.  
Use ARO pn / 98930-T bullet (installation tool) to aid in installation of  
(2) ꢀO" ring on (1) diaphragm rod.  
Secure the diaphragm pump legs to a suitable surface to insure  
against damage by vibration.  
S
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.  
For models with Teflon diaphragms: Item (8) Santoprene diaphragm  
is installed with the side marked ꢀAIR SIDE" towards the pump cen-  
ter body. Install the Teflon 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.

Air Motor Section Service is continued from Fluid Section repair.  
Inspect and replace old parts with new parts as necessary. Look for  
deep scratches on metallic surfaces, and nicks or cuts in ꢀO" rings.  
Take precautions to prevent cutting ꢀO" rings upon installation.  
Lubricate ꢀO" rings with Key-Lube grease.  
Do not over-tighten fasteners, refer to torque specification block on  
view.  
Re-torque fasteners following restart.  
[C] = Carbon Steel

MAJOR VALVE DISASSEMBLY  
1. Remove (107) plate (or leg depending on model), (108 and 117)  
gaskets.  
S
2. On the side opposite the air inlet, push on the inner diameter (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 ꢀO" rings.  
PILOT VALVE DISASSEMBLY  
1. Remove (104) retaining ring.  
2. Remove (123) screws and (122) ꢀO" rings.  
3. Remove (118) piston rod, (121) sleeve bushing, (119) ꢀO" rings and  
(120) spacers from the (101) motor body.  
MAJOR VALVE REASSEMBLY  
4. Remove (103) sleeve and (102) ꢀO" rings.  
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 in-  
ternal ports.  
2. Lubricate and carefully insert (111) spool.  
3. Install (117) gasket and (107).  
4. Lubricate and install (110) packing cup and insert (109) piston into  
(air inlet side) cavity, the (110) packing cup lips should point outward.  
5. Install (108) gasket and replace (107).  
PILOT VALVE REASSEMBLY  
1. Replace two (102) ꢀO" rings, if worn or damaged, and reinstall (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 retain on each  
end with the two (122) ꢀO" rings, retain with (123) screws.  
4. Replace (104) retaining rings.  
V ꢀSmart Parts", keep these items on hand in addition to the service kits for fast repair and reduction of down time.

Low output volume, erratic flow, or no flow.  
Check for diaphragm rupture.  
Check tightness of (14) diaphragm screw.

Check air supply.  
Check for plugged outlet hose.  
Check for kinked (restrictive) outlet material hose.  
Check for kinked (restrictive) or collapsed inlet material hose.  
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.  
Check all joints on the inlet manifolds and suction connections.  
These must be air tight.  
Air bubbles in product discharge.

Check connections of suction plumbing.  
Check ꢀO" rings between intake manifold and fluid caps.  
Check tightness of (14) diaphragm screw.

Inspect the pump for solid objects lodged in the diaphragm chamber  
or the seat area.
