Notice that the material inlet / outlet manifolds may be  
removed and rotated 180° to facilitate various mounting  
applications.  
If the body of the pump must be rotated, remove the end  
covers and manifolds and index it so the bolts line up  
properly. NOTE: The arrow on the end caps must always  
point upward for optimum performance.  
When the diaphragm pump is used in a force-feed situa-  
tion, it is recommended that a check valve be installed at  
the air inlet to keep material out of air line in the event of  
diaphragm failure.  
Secure diaphragm pump legs to a suitable surface to in-  
sure against damage by excessive vibration.

GENERAL DESCRIPTION  
The ARO U.L. listed pump for pumping petroleum products,  
offers high volume delivery even at low air pressures and  
easy self-priming. This model is designed specifically for  
transfer, bulk unloading or fueling applications. It includes a  
pressure relief valve (per U.L. Specification 79) which restricts  
the fluid outlet pressure to under 50 p.s.i. (3.4 bar). The relief  
valve can be plumbed to return the bleed off fuel to the stor-  
age container.  
y
y
AIR AND LUBE REQUIREMENTS  
WARNING EXCESSIVE AIR PRESSURE. Can cause pump  
and property damage. The air supply must be limited  
to 50 p.s.i.g. (3.4 bar) maximum inlet air pressure.  
OPERATING INSTRUCTIONS  
The air supply line or hose to the pump should be ad-  
equately sized to carry a sufficient volume of air to the  
pump. The material inlet supply tubing should not be too  
small or restrictive which will inhibit material flow. The  
outlet material volume is governed not only by the air  
supply but also by the material volume available at the  
inlet.  
Air supply provided should be filtered to provide clean  
dry air. 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 “Oring lubricant  
which is applied during assembly or repair.  
y
The pump should never be operated at pressures exceed-  
ing 50 p.s.i.g. (345 kPa) inlet air pressure. This pump is  
equipped with a pressure relief valve on the material out-  
let manifold which will open at 40 +/-4 p.s.i. (2.76 bar) to  
relieve pressure increases in the outlet hoses / plumbing  
caused by thermal expansion or other external forces.  
Disconnect the air supply from the pump if it is to be in-  
active for a few hours.  
y
y
y
y
MAINTENANCE  
Refer to the part views and descriptions as provided on  
pages 4 through 7 for parts identification and service kit in-  
formation.  
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.  
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  
diaphragm pump functions: 1. AIR SECTION, 2. FLUID  
SECTION. 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
y
INSTALLATION  
IMPORTANT  
Requirements for the installation are included in the  
y
y
y
Flammable and Combustible Liquids Code, NFPA No. 30,  
Automotive and Marine Service Station Code, NFPA No.  
30A and the National Electric Code, ANSI / NFPA No. 70.  
A fluid return hose which is compatible with the fluid be-  
ing pumped must be installed to the relief valve on the  
outlet manifold to return fluid back to the supply tank or  
pump inlet.  
y
y
y
Before disassembling, empty captured material in the  
outlet manifold by turning the pump upside down to  
drain material from the pump.  
The pump must be grounded to prevent static discharge.  
Grounding may be accomplished through the legs or to  
the ground lug provided on the pump.

AIR MOTOR SECTION SERVICE  
Service is divided into two parts - 1. Pilot Valve, 2. Major  
Valve.  
GENERAL REASSEMBLY NOTES:  
4. Replace (104) retaining rings.  
Air Motor Section service is continued from Fluid Section  
repair.  
y
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.  
Take precautions to prevent cutting “O” rings upon instal-  
lation.  
y
1. Remove (107) plate and (108 and 117) gaskets.  
2. On the side opposite the air inlet, push on the inner di-  
ameter of (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.  
y
Lubricate “Orings with Key-Lube grease or equivalent.  
Do not over-tighten fasteners. Refer to torque specifica-  
tion block on view.

1. Replace (112) washer, (114) “O” ring and (113) “O” ring  
onto (115) spacer and insert etc. NOTE: Be careful to ori-  
ent spacer legs away from blocking internal ports.  
2. Lubricate and carefully insert (111) spool.  
2. Remove (123) screws and (122) “Orings.  
3. Remove (118) pilot rod, (121) sleeve bushing, (119) “O”  
rings and (120) spacers from the (101) motor body.  
4. Remove (103) sleeve and (102) “Orings.  
3. Install (117) gasket and (107) plate.  
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) plate.

Check for kinked (restrictive) or collapsed inlet material  
hose.  
Air bubbles in product discharge.  
Check connections of suction plumbing.  
Check “Orings between intake manifolds and fluid caps.  
Check tightness of (14) diaphragm screw.  
y
y
y
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.  
y
Check all joints on the intake 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.
