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 666056-XXX and 66605H-XXX Groundable Acetal pumps: Use
the pump grounding screw provided. Connect a 12 ga. (minimum) wire (kit is included) 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 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.
Models 666056-X and 66605H-X: The Acetal material used in these
pumps contains stainless steel fibers. It’sconductivity allows it to be connected to a suitable ground. A ground screw and ground wire kit is provided for this.
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 page 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 available to service two separate diaphragm pump
functions: 1. AIR SECTION, 2. FLUID SECTION. The Fluid Section
is divided further to match typical active 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.
DUCKBILL CHECK VALVES (OPTIONAL)
Pumpmodels with the suffix (-0CX or -0DX) come equipped with duckbill
type checks. Standard duckbill pumps are shipped with the material inlet
in the top and the material outlet on the bottom manifold. To change the
direction of flow, disassemble the pump as instructed in the FLUID SECTION and reassemble as described below.A pump that was factory built
with balls and seats can be retro-fitted with duckbill type check valves by
purchasing the necessary parts and installing them as shown.
Reassembly:
The duckbills may be installed in either direction to produce flow from top
to bottom of the pump or from bottom to top of the pump. In either case,
all of the (42) duckbills must point in the same d irection.
Flow from Top to Bottom: (see page 5)
1. With (15) fluid caps installed, stand the pump upside down.
2. Place (21) insert into (42) duckbill and slide (41) sleeve over (42)
duckbill.
3. Slide the complete check assembly into the fluid cap bore with the
(21) insert end first. [Duckbills (42) point up.]
4. Position (19) “O” ring over (41) sleeve.
5. Attach (35) manifold feet / (36) swivel assembly to the fluid caps.
6. Turn pump over to right side up position.
7. Assemble duckbill check as in step #1.
8. Slide the complete check assembly into the fluid cap bore with the
(41) sleeve end first. [Duckbill is pointing down toward fluid cap cavity.]
9. Position (19) “O” ring around (21) insert.
10. Attach (34) manifold / (36) swivel assembly to fluid cap.
Flow from Bottom to Top: (Inlet Bottom - Outlet Top)
To reverse flow direction, slide check valve assemblies into the (15) fluid
caps backwards from what is indicated in steps #2 and #7. In step #2, the
(42) duckbills will be pointing down and in step #7, they will be pointing
up.
