WARNING
EXCESSIVE AIR PRESSURE. Can cause per-
sonal injury, pump damage or property damage.
Do not exceed the maximum inlet air pressure as
stated on the pump model plate.
Be sure material hoses and other components are able
to withstand fluid pressures developed by this pump.
Check all hoses for damage or wear. Be certain dispens-
ing device is clean and in proper working condition.
WARNING
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, ushing, recirculating or
spraying ammable 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, hos-
es and any object to which material is being pumped.
Secure pump, connections and all contact points to
avoid vibration and generation of contact or static spark.
Consult local building codes and electrical codes for
specic grounding requirements.
After grounding, periodically verify continuity of
electrical path to ground. Test with an ohmmeter
from each component (e.g., hoses, pump, clamps, con-
tainer, spray gun, etc.) to ground to ensure 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.
WARNING
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 muer.
Pipe the exhaust to a safe remote location when
pumping hazardous or inammable materials.
Use a grounded 3/8” minimum i.d. hose between the
pump and the muer.
WARNING
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.

WARNING
MISAPPLICATION HAZARD. Do not use
models containing aluminum wetted parts with food
products for human consumption. Plated parts can
contain trace amounts of lead.
CAUTION
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,
ushed or circulated. For specic uid compatibility,
consult the chemical manufacturer.
CAUTION
Maximum temperatures are based
on mechanical stress only. Certain chemicals will
significantly 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.
CAUTION
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.
CAUTION
Do not use the pump for the structural
support of the piping system. Be certain the system
components are properly supported to prevent stress
on the pump parts.
Suction and discharge connections should be exible
connections (such as hose), not rigid piped, and should
be compatible with the substance being pumped.
CAUTION
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.
CAUTION
Use only genuine ARO replacement parts
to assure compatible pressure rating and longest
service life.

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.


INSTALLATION
Verify correct model / conguration prior to installation.
Retorque all external fasteners per specications prior to
start up.
Pumps are tested in water at assembly. Flush pump with
compatible uid prior to installation.
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.
Material supply tubing should be at least the same diam-
eter as the pump inlet manifold connection.
Material supply hose must be reinforced, non-collapsible
type compatible with the material being pumped.
Piping must be adequately supported. Do not use the
pump to support the piping.
Use flexible connections (such as hose) at the suction
and discharge. These connections should not be rigid
piped and must be compatible with the material being
pumped.
Secure the diaphragm pump legs to a suitable surface
(level and at) to ensure against damage by vibration.
Pumps that need to be submersed must have both wet
and non-wet components compatible with the material
being pumped.
Submersed pumps must have exhaust pipe above liquid
level. Exhaust hose must be conductive and grounded.

AIR AND LUBE REQUIREMENTS
WARNING
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 lu-
brication 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.


GENERAL DESCRIPTION
The ARO diaphragm pump oers 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 / uid
sections.
Air operated double diaphragm pumps utilize a pressure dif-
ferential in the air chambers to alternately create suction and
positive uid pressure in the uid chambers, ball checks en-
sure 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 maxi-
mum line pressure is reached (dispensing device closed) and
will resume pumping as needed.

DIMENSIONAL DATA
Low output volume, erratic ow, or no ow.
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 ow if high viscosity uids are being
pumped. Suction hose must be a non-collapsing type,
capable of pulling a high vacuum.
Check all joints on the inlet 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.
