NOTICE: All possible options are shown in the chart, however, certain combinations may not be recommended, consult a representative or the factory if you
have questions concerning availability.
The ARO Diaphragm Pump oers 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 resistant design, modular air motor / uid sections.
Air operated double diaphragm pumps utilize a pressure dierential in
the air chambers to alternately create suction and positive uid pressure in the uid 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.

OPERATING AND SAFETY PRECAUTIONS
READ, UNDERSTAND, AND FOLLOW THIS INFORMATION TO AVOID INJURY AND PROPERTY DAMAGE.
Obtain Material Safety Data Sheets on all materials from
EXC ESSI VE AIR PRE SSUR E
STATIC SPARK
EXCESSIVE AIR PRESSURE. Can cause per-
sonal injury, pump damage or property damage.
Be sure material hoses and other components are able to
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.
Do not exceed the maximum inlet air pressure as stated on
the pump model plate.
STATIC SPARK. Can cause explosion resulting
in severe injury or death. Ground pump and pumping
system.
Sparks can ignite ammable material and vapors.
The pumping system and object being sprayed must be
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 vi-
bration and generation of contact or static spark.
Consult local building codes and electrical codes for spe-
cic grounding requirements.
After grounding, periodically verify continuity of electrical
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
in the material being dispensed if possible. (Avoid free
streaming of material being dispensed.)
Use hoses incorporating a static wire.
Use proper ventilation.
Keep inflammables away from heat, open flames and
sparks.
Keep containers closed when not in use.
Pump exhaust may contain contaminants.
Can cause severe injury. Pipe exhaust away from work area
and personnel.
In the event of a diaphragm rupture, material can be forced
out of the air exhaust muer.
Pipe the exhaust to a safe remote location when pumping
hazardous or inammable materials.
Use a grounded 3/8” minimum i.d. hose between the pump
and the muer.
HAZARDOUS PRESSURE. Can result in serious
injury or property damage. Do not service or clean pump,
hoses or dispensing valve while the system is pressurized.
Disconnect air supply line and relieve pressure from the
system by opening dispensing valve or device and / or
carefully and slowly loosening and removing outlet hose or
piping from pump.
HAZARDOUS MATERIALS. Can cause serious
injury or property damage. Do not attempt to return
a pump to the fac tory or service center that contains
hazardous material. Safe handling practices must comply
with local and national laws and safety code requirements.

halogenated hydrocarbon solvents which may react and
explode.
Check pump motor section, fluid caps, manifolds and all
wetted parts to assure compatibility before using with solvents of this type.
Verify the chemical compatibility of the pump
wetted parts and the substance being pumped, flushed
or recirculated. Chemical compatibility may change with
temperature and concentration of the chemical(s) within
the substances being pumped, flushed or circ ulated.
For specific fluid compatibil ity, cons ult the chemical
manufacturer.

mechanical stress only. Certain chemicals will signicantly
reduce maximum safe operating temperature. Consult
the chemical manufacturer for chemical compatibility and
temperature limits. Refer to PUMP DATA on page 1 of this
manual.
Be certain all operators of this equipment
have been trained for safe working practices, understand
it’s limitations, and wear safety goggles / equipment when
required.
Do not use the pump for th e structural
su pport o f the piping system. B e certain the syste m
components are properly supported to prevent stress on
the pump parts.
Suction and discharge connections should be flexible con-
nections (such as hose), not rigid piped, and should be compatible with the substance being pumped.
Prevent unnecessary damage to the pump.
Do not allow pump to operate when out of material for
long periods of time.
Disconnect air line from pump when system sits idle for
long periods of time.
Use only genuine ARO replacement parts to
assure compatible pressure rating and longest service life

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 lubrication required other than the “O” ring lubricant which is
applied during assembly or repair.
If lubricated air is present, make sure that is compatible
with the Nitrile “O” rings in the air motor section of the
pump.
OPERATING INSTRUCTIONS
Always ush 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 (ooded
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 in-
sure against damage by vibration.
MAINTENANCE
Refer to the part views and descriptions as provided on page 4
through 7 for parts identication and Service Kit information.
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 SECTION. 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.
