WARNING
injury, pump damage or property damage.
Do not exceed the maximum inlet air pressure as stated on
y
the pump model plate.
Be sure material hoses and other components are able to
y
withstand uid pressures developed by this pump. Check all
hoses for damage or wear. Be certain dispensing device is
clean and in proper working condition.

Sparks can ignite ammable material and vapors.
y
The pumping system and object being sprayed must be
y
grounded when it is pumping, flushing, recirculating or
spraying flammable materials such as paints, solvents,
lacquers, etc. or used in a location where surrounding atmosphere is conducive to spontaneous combustion. Ground the
dispensing valve or device, containers, hoses and any object
to which material is being pumped.
Secure pump, connections and all contact points to avoid
y
vibration and generation of contact or static spark.
Consult local building codes and electrical codes for spe-
y
ci c grounding requirements.
After grounding, periodically verify continuity of electrical
y
path to ground. Test with an ohmmeter from each component (e.g., hoses, pump, clamps, container, spray gun, etc.)
to ground to insure continuity. Ohmmeter should show 0.1
ohms or less.
Submerse the outlet hose end, dispensing valve or device
y
in the material being dispensed if possible. (Avoid free
streaming of material being dispensed.)
Use hoses incorporating a static wire.
y
Use proper ventilation.
y
Keep inflammables away from heat, open flames and
y

Use a grounded 3/8” minimum i.d. hose between the pump
y
and the mu er.
WARNING

hoses or dispensing valve while the system is pressurized.
Disconnect air supply line and relieve pressure from the
y
system by opening dispensing valve or device and / or
carefully and slowly loosening and removing outlet hose or
piping from pump.

GENERAL DESCRIPTION
The ARO U.L. listed pump for pumping petroleum products, o ers
high volume delivery at low air pressures and easy self-priming.
This model is designed specifically for transfer, bulk un-loading
or fueling applications. It includes a pressure relief valve (per U. L.
Speci cation 79) which restricts the uid outlet pressure to under
50 p.s.i. (3.4 bar). The relief valve must be plumbed to return the
bleed o fuel to the storage container.
Air operated double diaphragm pumps utilize a pressure di erential in the air chambers to alternately create suction and positive
fluid pressure in the fluid chambers, ball checks insure a positive
ow of uid.
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 maximum line
pressure is reached (dispensing device closed) and will resume
pumping as needed.
AIR AND LUBE REQUIREMENTS
WARNING
age, personal injury or property damage. The air supply
must be limited to 50 p.s.i.g. (3.4 bar) maximum inlet air
pressure.
A lter capable of ltering out particles larger than 50 microns
y
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
y
the “O” rings and seals in the air motor section of the pump.
EXCESSIVE AIR PRESSURE. Can cause pump dam-
INSTALLATION
IMPORTANT
Requirements for the installation are included in the Flam-
y
mable 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 being
y
pumped must be installed to the relief valve on the outlet
manifold to return uid back to the supply tank or pump inlet.
The pump must be grounded to prevent static discharge.
y
Grounding may be accomplished through the legs or to the
ground lug provided on the pump.
OPERATING INSTRUCTIONS
The pump should never be operated at pressures exceeding 50
y
p.s.i.g. (345 kPa) inlet air pressure. This pump is equipped with a
pressure relief valve on the material outlet 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.
Always ush the pump with a solvent compatible with the ma-
y
terial 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
y
for a few hours.
The outlet material volume is governed not only by the air sup-
y
ply, 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 ( ooded
y
inlet) situation, it is recommended that a “check valve” be installed at the air inlet.
Secure the diaphragm pump legs to a suitable surface to insure
y
against damage by vibration.
MAINTENANCE
Certain ARO “Smart Parts” are indicated which should be avail-
y
able for fast repair and reduction of down time.
Provide a clean work surface to protect sensitive internal mov-
y
ing parts from contamination from dirt and foreign matter during service disassembly and reassembly.
Keep good records of service activity and include the pump in
y
preventive maintenance program.
Service kits are available to service two separate diaphragm
y
pump functions: 1. AIR SECTION, 2. FLUID SECTION. The Fluid
Section is divided further to match typical active Material Options.
Before disassembling, empty captured material in the outlet
y
manifold by turning the pump upside down to drain material
from the pump.
