GENERAL DESCRIPTION
The ARO diaphragm pump offers high volume delivery even
at low air pressure and a broad range of material compatibil-
ity options are available. Refer to the model and option chart.
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.
Pump cycling will begin as air pressure is applied and 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.
AIR AND LUBE REQUIREMENTS
WARNING
EXCESSIVE AIR PRESSURE. Can cause per-
sonal injury, pump damage or property damage. Do
not exceed maximum inlet air pressure as stated on
air motor plate.
y
Filtered and oiled air will allow the pump to operate more
efficiently and yield a longer life to operating parts and
mechanisms.
y
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
If lubricated air is present, make sure that it is compatible
with the Nitrile “O” rings in the air motor section of the
pump.
TRANSPORT AND STORAGE
y
Store in a dry place, do not remove product from box
during storage.
y
Do not remove protection caps from inlet and outlet
prior to installation.
y
Do not drop or damage box, handle with care.
INSTALLATION
y
Pump cycle rate and operating pressure should be con-
trolled by using an air regulator on the air supply.
y
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.
GENERAL PRODUCT SAFETY INFORMATION:
WARNING
EXCESSIVE AIR PRESSURE. Can cause per-
sonal injury, pump damage or property damage.
y
Do not exceed the maximum inlet air pressure as stat-
ed on the pump model plate.
y
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
dispensing device is clean and in proper working con-
dition.
WARNING
Pump exhaust may contain contaminants.
Can cause severe injury. Pipe exhaust away from work
area and personnel.
y
In the event of a diaphragm rupture material can be
forced out of the air exhaust muffler.
y
Pipe the exhaust to a safe remote location when
pumping hazardous or inflammable materials.
y
Use a grounded 3/4” minimum ID hose between the
pump and the muffler.
WARNING
HAZARDOUS PRESSURE. Can result in seri-
ous injury or property damage. Do not service or clean
pump, hoses or dispensing valve while the system is
pressurized.
y
Disconnect air supply line and relieve pressure from
the system by opening dispensing valve or device and
/ or carefully and slowly loosening and removing out-
let hose or piping from pump.
WARNING
HAZARDOUS MATERIALS. Can cause serious
injury or property damage. Do not attempt to return
a pump to the factory or service center that contains
hazardous material. Safe handling practices must
comply with local and national laws and safety code
requirements.
y
Obtain Material Safety Data Sheets on all materials
from the supplier for proper handling instructions.
WARNING
EXPLOSION HAZARD. Models containing
aluminum wetted parts cannot be usedwith 1, 1, 1
- Trichloroethane, Methylene Chloride or other Halo-
genated Hydrocarbon solvents which may react and
explode.
y
Check pump motor section, fluid caps, manifolds and
all wetted parts to assure compatibility before using
with solvents of this type.
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,
flushed or circulated. For specific fluid compatibility,
consult the chemical manufacturer.
CAUTION
Be certain all operators of this equipment
have been trained for safe working practices, under-
stand it’s limitations, and wear safety goggles / equip-
ment when required.
CAUTION
Do not use the pump for the structural sup-
port of the piping system. Be certain the system com-
ponents are properly supported to prevent stress on
the pump parts.
y
Suction and discharge connections should be flex-
ible 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.
y
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.
