OPERATING AND SAFETY PRECAUTIONS

READ, UNDERSTAND AND FOLLOW THIS INFORMATION TO AVOID INJURY AND PROPERTY DAMAGE.

EXCESSIVE AIR PRESSURE
STATIC SPARK

WARNING

EXCESSIVE AIR PRESSURE. Can cause per­sonal injury, pump damage or property damage.
Do not exceed the maximum inlet air pressure as

y

stated on the pump model plate.
Be sure material hoses and other components are able

y

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.

WARNING

STATIC SPARK. Can cause explosion resulting
in severe injury or death. Ground pump and pumping
system.
Sparks can ignite  ammable material and vapors.

y

The pumping system and object being sprayed must be

y

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, hos­es and any object to which material is being pumped.
Secure pump, connections and all contact points to

y

avoid vibration and generation of contact or static
spark.
Consult local building codes and electrical codes for

y

speci c grounding requirements.
After grounding, periodically verify continuity of

y

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

y

device 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 in ammables away from heat, open  ames and

y

sparks.
Keep containers closed when not in use.

y

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

y

forced out of the air exhaust mu er.
Pipe the exhaust to a safe remote location when

y

pumping hazardous or in ammable materials.
Use a grounded 3/8” minimum i.d. hose between the

y

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.
Disconnect air supply line and relieve pressure from

y

the system by opening dispensing valve or device and
/ or carefully and slowly loosening and removing out­let hose or piping from pump.

WARNING

HAZARDOUS MATERIALS. Can cause serious
injury or property damage. Do not attempt to return

HAZARDOUS MATERIALS
HAZARDOUS PRESSURE

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.
Obtain Material Safety Data Sheets on all materials

y

from the supplier for proper handling instructions.

WARNING

EXPLOSION HAZARD. Models containing
aluminum parts cannot be used with 1,1,1-trichloro­ethane, methylene chloride or other halogenated hy­drocarbon solvents which may react and explode.
Check pump motor section,  uid caps, manifolds and

y

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,
 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

y

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

y

for long periods of time.

CAUTION

Use only genuine ARO® replacement parts to
assure compatible pressure rating and longest service
life.

NOTICE

Install the pump in the vertical position.
The pump may not prime properly if the balls do not
check by gravity upon start-up.

NOTICE

Re-torque all fasteners before operation.
Creep of housing and gasket materials may cause
fasteners to loosen. Re-torque all fasteners to insure
against  uid or air leakage.

NOTICE

Replacement warning labels are available
upon request: “Static Spark” pn \ 93616-1, Diaphragm
Rupture” pn \ 93122.

WARNING

= Hazards or unsafe practices which

could result in severe personal injury,
death or substantial property damage.

CAUTION

= Hazards or unsafe practices which

could result in minor personal injury,
product or property damage.

NOTICE

= Important installation, operation or

maintenance information.

GENERAL DESCRIPTION

The ARO diaphragm pump o ers high volume delivery even
at low air pressure and a broad range of material compatibil­ity options are 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 dif­ferential in the air chambers to alternately create suction and
a 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

damage, personal injury or property damage.

A filter capable of filtering out particles larger than 50

y

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 it is compatible

y

with the “O” rings and seals in the air motor section of the
pump.

EXCESSIVE AIR PRESSURE. Can cause pump

OPERATING INSTRUCTIONS

Always flush the pump with a solvent compatible with

y

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 in-

y

active for a few hours.
The outlet material volume is governed not only by the

y

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

y

( 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

y

insure against damage by vibration.

MAINTENANCE

Certain ARO “Smart Parts” are indicated which should be

y

available for fast repair and reduction of down time.
Provide a clean work surface to protect sensitive internal

y

moving parts from contamination from dirt and foreign
matter during service disassembly and reassembly.
Keep good records of service activity and include the

y

pump in preventive maintenance program.
Service kits are available to service two separate dia-

y

phragm 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

y

outlet manifold by turning the pump upside down to
drain material from the pump.
