S Sparks can ignite flammable material and vapors.
S The pumping system and object being sprayed must be
grounded when it is pumping, flushing, recirculating or spraying flammable 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.
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 After grounding, periodically verify continuity of 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.

GENERAL DESCRIPTION
MAINTENANCE
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, ball 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 O"
rings and seals in the air motor section of the pump.
OPERATING INSTRUCTIONS
S Always 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.
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 pages 4 through
7 for parts identification and service kit information.
S Certain ARO Smart Parts" are indicated 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. AIR SECTION, 2. FLUID SECTION. The FLUID SECTION is divided further to match typical part MATERIAL OPTIONS.
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 top manifold(s).
2. Remove (22) balls, (19) O" rings and (21) seats.
3. Remove (15) fluid caps.
NOTE: Only Teflon diaphragm models use a primary diaphragm (7) and
a backup diaphragm (8). Refer to the auxiliary view in the Fluid Section
illustration.
4. Remove the (14) screws, (6) washers, (7) or (7 / 8) diaphragms and
(5) washers.
5. Remove (3) O" rings.
NOTE: Do not scratch or mar the surface of (1) diaphragm rod.
FLUID SECTION REASSEMBLY
S Reassemble in reverse order.
S Clean and inspect all parts. Replace worn or damaged parts with
new parts as required.
S Lubricate (1) diaphragm rod and (2) O" ring with Key-LubeR grease.
S Use ARO pn / 98930-T bullet (installation tool) to aid in installation of
(2) O" ring on (1) diaphragm rod.
S Be certain (7) or (7 / 8) diaphragm(s) align properly with (15) fluid
caps before making final torque adjustments on bolt and nuts to
avoid twisting the diaphragm.
S For models with Teflon diaphragms: Item (8) Santoprene diaphragm
is installed with the side marked AIR SIDE" towards the pump center body. Install the Teflon diaphragm with the side marked FLUID
SIDE" towards the fluid cap.
S Re-check torque settings after pump has been re-started and run a
while.
