for damage or wear. Be certain dispensing device is clean and
in proper working condition.

S Use 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.

S Secure pump, connections and all contact points to avoid

vibration and generation of contact or static spark.

S Consult local building codes and electrical codes for specific

grounding requirements.

S Aftergrounding, periodically verify continuityof 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.

S Submerse the outlet hose end, dispensing valve or device in

the material being dispensed if possible. (Avoid free streaming
of material being dispensed.)

S Use hoses incorporating a static wire.
S Use proper ventilation.
S Keep inflammables away from heat, open flames and sparks.
S Keep containers closed when not in use.

GENERAL DESCRIPTION

PARTS AND SERVICE KITS

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, valve 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 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.

EXCESSIVE AIR PRESSURE. Can cause pump

S 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.

S If 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

Always flush the pump with a solvent compatible with the material

S

being pumped if the material being pumped is subject to “setting up”
when not in use for a period of time.

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

hours.

S 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.

S When 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.

S Secure the diaphragm pump legs to a suitable surface to insure

against damage by vibration.

Refer to the part views and descriptions as provided on page 4 through 7
for parts identification and Service Kit information.

S Certain ARO “Smart Parts” areindicated which should be available

for fast repair and reduction of down time.

S Service kits are divided to service two separate diaphragm pump

functions:1.AIRSECTION,2.FLUIDSECTION.TheFLUIDSEC­TION is divided further to match typical part MATERIAL OPTIONS.

MAINTENANCE

S

Provide a clean work surface to protect sensitive internal moving
parts from contamination from dirt and foreign matter during service
disassembly and reassembly.

S Keep good records of service activity and include pump in preven-

tive maintenance program.

S Before disassembling, empty captured material in the outlet man-

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

FLUID SECTION DISASSEMBLY

1. Remove (61) outlet manifold, (60) inlet manifold.

2. Remove (22) balls, (19) “O” rings (if applicable) and (21) seats.

3. Remove (15) fluid caps.
NOTE: Only PTFE diaphragm models use a primary diaphragm (7) and
a backup diaphragm (8). Refer to the auxiliary view in the Fluid Section
illustration.

4. Removethe (6) diaphragm washer, (7) or (7 / 8) diaphragms, and (5)
backup washer.

NOTE: Do not scratch or mar the surface of (1) diaphragm rod.

FLUID SECTION REASSEMBLY

S

Reassemble in reverse order. Refer to the torque requirements on
page 5.

S Clean and inspect all parts. Replace worn or damaged parts with

new parts as required.

S Lubricate (1) diaphragm rod and (144) “U” cup with LubriplateR

FML-2 grease (94276 grease packet is included in service kit).

S For models with PTFE diaphragms: Item (8) Santoprene diaphragm

is installed with the side marked “AIR SIDE”towards the pump cen­ter body. Install the PTFE diaphragm (7) with the side marked
“FLUID SIDE” towards the (15) fluid cap.

S Re-check torque settings after pump has been re-started and run a

while.
