OPERATING INSTRUCTIONS  
WARNING = Hazards or unsafe practices which  
could result in severe personal injury,  
death or substantial property damage.  
CAUTION = Hazards or unsafe practices which  
could result in minor personal injury,  
product or property damage.  
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 in-  
active 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 col-  
lapse.  
When the diaphragm pump is used in a forced-feed  
(flooded inlet) situation, it is recommended that a “check  
valvebe installed at the air inlet.  
y
y
y
NOTICE  
= Important installation, operation or  
maintenance information.  
GENERAL DESCRIPTION  
The ARO diaphragm pump offers high volume delivery even  
at low air pressure. ARO pumps feature stall resistant design,  
modular air motor / fluid sections.  
Air operated double diaphragm pumps utilize a pressure dif-  
ferential in the air chambers to alternately create suction and  
a positive fluid pressure in the fluid chambers, ball checks  
insure a positive flow of fluid.  
y
y
Secure the diaphragm pump legs to a suitable surface to  
insure against damage by vibration.  
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 pressure and will stop cycling once maxi-  
mum line pressure is reached (dispensing device closed) and  
will resume pumping as needed.  
MAINTENANCE  
Refer to the part views and descriptions as provided on  
pages 4 through 7 for parts identification and service kit in-  
formation.  
Certain ARO “Smart Parts” are indicated which should be  
available for fast repair and reduction of down time.  
Service kits are available to service two separate dia-  
phragm pump functions: 1. AIR SECTION, 2. FLUID SEC-  
TION. The Fluid Section is divided further to match typical  
active 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 the  
pump in preventive maintenance program.  
y
AIR AND LUBE REQUIREMENTS  
WARNING EXCESSIVE AIR PRESSURE. Can cause pump  
y
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.  
y
y
y
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.  
y
y
Before disassembling, empty captured material in the  
outlet manifold by turning the pump upside down to  
drain material from the pump.

AIR MOTOR SECTION SERVICE  
Service is divided into two parts - 1. Pilot Valve, 2. Major  
Valve.  
MAJOR VALVE DISASSEMBLY  
GENERAL REASSEMBLY NOTES:  
1. Remove (135) valve block and (233) adapter plate, expos-  
ing (166 and 132) gaskets and (176) checks.  
2. Remove (233) adapter plate, releasing (140) valve insert,  
(141) valve plate, (199, 200 and 241) gaskets and (243 and  
244) “Orings.  
3. Remove (136) plug and (137) “O” ring, releasing (111)  
spool.  
Air Motor Section service is continued from Fluid Section  
repair.  
Inspect and replace old parts with new parts as neces-  
sary. Look for deep scratches on metallic surfaces, and  
nicks or cuts in “Orings.  
y
y
Take precautions to prevent cutting “O” rings upon instal-  
lation.  
y
Lubricate “Orings with Lubriplate FML-2 grease.  
Do not over-tighten fasteners. Refer to torque specifica-  
tion block on view.  
Re-torque fasteners following restart.  
SERVICE TOOLS - To aid in the installation of (168) “O”  
rings onto the (167) pilot piston, use tool # 204130-T,  
available from ARO.  
y
y
MAJOR VALVE REASSEMBLY  
1. Install new (138 and 139) “U” cups on (111) spool - LIPS  
MUST FACE EACH OTHER.  
y
y
2. Insert (111) spool into (135) valve housing.  
3. Install (137 and 242) “O” rings on (136) plug and assemble  
plug to (135) valve housing, securing with (105) screws.  
4. Install (140) valve insert, (141) valve plate, (199) gasket  
and (243 and 244) “O” rings into (135) valve housing.  
NOTE: Assemble (140) valve insert with “dished” side to-  
ward (141) valve plate. Assemble (141) valve plate with  
part number identification toward (140) valve insert.  
5. Assemble (200 and 241) gaskets and (233) adapter plate  
to (135) valve housing, securing with (240) screws.  
6. Assemble (132 and 166) gaskets and (176) checks to (101)  
center body.  
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.  
PILOT VALVE REASSEMBLY  
7. Assemble (135) valve housing and components to (101)  
center body, securing with (134) screws.  
1. Clean and lubricate parts not being replaced from service  
kit.

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 intake manifolds and suction con-  
nections. These must be air tight.
