OPERATING AND SAFETY PRECAUTIONS

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

EXCESSIVE AIR PRESSURE

STATIC SPARK

HAZARDOUS MATERIALS

HAZARDOUS PRESSURE

WARNING EXCESSIVE AIR PRESSURE. Can cause person-

al injury, pump damage or property damage.

SDo not exceed the maximum inlet air pressure as stated on the

pump model plate.

SBe sure material hoses and other components are able to with-

stand fluid 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.

SUse the pump grounding screw terminal provided. Use ARO

part no. 66885-1 ground kit or connect a suitable ground wire

(12 ga. min.) to a good earth ground source.

SSecure pump, connections and all contact points to avoid

vibration and generation of contact or static spark.

SConsult local building codes and electrical codes for specific

grounding requirements.

SAftergrounding, periodicallyverifycontinuityof 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.

SSubmerse the outlet hose end, dispensing valve or device in

the material being dispensed if possible. (Avoid free streaming

of material being dispensed.)

SUse hoses incorporating a static wire.

SUse proper ventilation.

SKeep inflammables away from heat, open flames and sparks.

SKeep containers closed when not in use.

WARNING Pump exhaust may contain contaminants. Can

causesevereinjury. Pipe exhaust awayfromworkareaandper-

sonnel.

SIn the event of a diaphragm rupture, material can be forced out

of the air exhaust muffler.

SPipe the exhaust to a safe remote location when pumping haz-

ardous or inflammable materials.

SUse a grounded 1” minimum i.d. hose between the pump and

the muffler.

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.

SDisconnect air supply line and relieve pressure from the sys-

tem by opening dispensing valve or device and / or carefully

and slowly loosening and removing outlet hose or piping from

pump.

WARNING HAZARDOUS MATERIALS.Cancauseseriousin-

jury 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.

SObtain Material Safety Data Sheets on all materials from the

supplier for proper handling instructions.

WARNING EXPLOSION HAZARD. Models containing alumi-

num wetted parts cannot be used with III.-Trichloroethane, Me-

thylene Chloride or other Halogenated Hydrocarbon solvents

which may react and explode.

SCheck pump motor section, fluid caps, manifolds and all

wetted parts to assure compatibility before using withsolvents

of this type.

WARNING MISAPPLICATION HAZARD. Do not use models

containing aluminum wetted parts with food products for hu-

man 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 re-

circulated. Chemical compatibility may change with tempera-

ture and concentration of the chemical(s) within the

substances being pumped, flushed or circulated. For specific

fluid compatibility, consult the chemical manufacturer.

CAUTION Maximum temperatures are based on mechani-

cal stress only. Certain chemicals will significantly reduce

maximum safe operating temperature. Consult the chemical

manufacturer for chemical compatibility and temperature lim-

its.RefertoPUMPDATAonpage1ofthismanual.

CAUTION Be certain all operators of this equipment have

been trained for safe working practices, understand it’s limita-

tions, 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.

SSuction and discharge connections should be flexible connec-

tions (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 forlong periods

of time.

SDisconnect air line from pump when system sits idle for long

periods of time.

CAUTION Use only genuine ARO replacement parts to as-

sure compatible pressure rating and longest service life.

NOTICE Replacement warning labels are available upon

request: “Static Spark & Diaphragm Rupture” pn \ 94080.

GENERAL DESCRIPTION

The ARO diaphragm pump offers 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 / fluid sections.

Air operated double diaphragm pumps utilize a pressure differential in

the air chambers to alternately create suction and positive fluid pressure

in the fluid chambers, flap checks insure a positive flow of fluid.

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 pres-

sure and will stop cycling once maximum line pressure is reached (dis-

pensing device closed) and will resume pumping as needed.

AIR AND LUBE REQUIREMENTS

WARNING EXCESSIVE AIR PRESSURE. Can cause pump

damage, personal injury or property damage.

SA 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.

SIf lubricated air is present, make sure that it is compatible with the

Nitrile “O” rings in the air motor section of the pump.

OPERATING INSTRUCTIONS

SAlways flush 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.

SDisconnect the air supply from the pump if it is to be inactive for a few

hours.

SThe 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.

SWhen the diaphragm pump is used in a forced-feed (flooded inlet)

situation, it is recommended that a “Check Valve” be installed at the

air inlet.

SSecure the diaphragm pump legs to a suitable surface to insure

against damage by vibration.

PARTS AND SERVICE KITS

Refer to the part views and descriptions as provided on page 4 through 7

for parts identification and Service Kit information.

SCertain ARO “Smart Parts” are indicated which should be available

SService kits are divided to service two separate diaphragm pump

functions:1.AIRSECTION,2.FLUIDSECTION.TheFLUIDSEC-

TION is divided further to match typical part MATERIAL OPTIONS.

MAINTENANCE

SProvide a clean work surface to protect sensitive internal moving

parts from contamination from dirt and foreign matter during service

disassembly and reassembly.

SKeep good records of service activity and include pump in preven-

tive maintenance program.

SBefore disassembling, empty captured material in the outlet man-

ifold by turning the pump upside down to drain material from the

pump.
