y
the pump model plate. Be sure material hoses and other components are able to
y
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
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 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. Use the pump grounding screw terminal provided. Use ARO®
y
part no. 66885-1 ground kit or connect a suitable ground wire (12 ga. minimum) to a good earth ground source. Secure pump, connections and all contact points to avoid
y
vibration and generation of contact or static spark. Consult local building codes and electrical codes for spe-
y
ci c grounding requirements. After grounding, periodically verify continuity of electrical
y
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 device
y
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 inflammables away from heat, open flames and
y
sparks. Keep containers closed when not in use.

WARNING
cause severe injury. Pipe exhaust away from work area and personnel. In the event of a diaphragm rupture, material can be forced
y
out of the air exhaust mu er. Pipe the exhaust to a safe remote location when pumping
y
hazardous or in ammable materials. Use a grounded 3/4” minimum i.d. hose between the pump
y
and the mu er.
WARNING
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 the
y
system by opening dispensing valve or device and / or carefully and slowly loosening and removing outlet hose or piping from pump.

GENERAL DESCRIPTION
MAINTENANCE
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 di eren­tial in the air chambers to alternately create suction and a positive  uid pressure in the  uid chambers, valve checks insure a positive  ow of  uid. Pump cycling will begin as air pressure is applied and 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
age, personal injury or property damage.
A  lter capable of  ltering out particles larger than 50 microns
y
should be used on the air supply. There is no lubrication re-
quired other than the “O” ring lubricant which is applied during
assembly or repair.
If lubricated air is present, make sure that it is compatible with
y
the “O” rings and seals in the air motor section of the pump.
EXCESSIVE AIR PRESSURE. Can cause pump dam-
OPERATING INSTRUCTIONS
Always  ush the pump with a solvent compatible with the ma-
y
terial 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 inactive
y
for a few hours.
The outlet material volume is governed not only by the air sup-
y
ply, 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 ( ooded
y
inlet) situation, it is recommended that a “check valve” be in-
stalled at the air inlet.
Secure the diaphragm pump legs to a suitable surface to insure
y
against damage by vibration.
Refer to the part views and descriptions as provided on pages 4 through 7 for parts identi cation and service kit information.
Certain ARO “Smart Parts” are indicated which should be avail-
y
able for fast repair and reduction of down time. Service kits are divided to service two separate diaphragm
y
pump functions: 1. AIR SECTION, 2. FLUID SECTION. The Fluid Section is divided further to match typical part Material Op­tions. Provide a clean work surface to protect sensitive internal mov-
y
ing parts from contamination from dirt and foreign matter dur­ing service disassembly and reassembly. Keep good records of service activity and include the pump in
y
preventive maintenance program. Before disassembling, empty captured material in the outlet
y
manifold by turning the pump upside down to drain material from the pump.
FLUID SECTION DISASSEMBLY
Remove top manifold(s).
1. Remove (22) balls, (19) “O” rings (where applicable) and (21)
2. seats. Remove (15)  uid caps.
3.
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. Remove the (14) screw, (6) washer, (7) or (7 / 8) diaphragm, (196) cushion and (5) washer.
NOTE: Do not scratch or mar the surface of (1) diaphragm rod.
FLUID SECTION REASSEMBLY
Reassemble in reverse order.
y
Clean and inspect all parts. Replace worn or damaged parts
y
with new parts as required. Lubricate (1) diaphragm rod and (2) “O” ring with Key-Lube “O”
y
ring lube. Use ARO pn / 98931-T bullet (installation tool) to aid in installa-
y
tion of (2) “O” ring on (1) diaphragm rod. Be certain (7) or (7 / 8) diaphragms align properly with (15)  uid
y
caps before making  nal torque adjustments on bolt and nuts to avoid twisting the diaphragms. For models with PTFE diaphragms: Item (8) Santoprene dia-
y
phragm is installed with the side marked “AIR SIDE” towards the pump center body. Install the PTFE diaphragm with the side marked “FLUID SIDE” towards the  uid cap. Re-check torque settings after the pump has been re-started
y

AIR MOTOR SECTION SERVICE
Service is divided into two parts - 1. Pilot Valve, 2. Major Valve. GENERAL REASSEMBLY NOTES:
Air Motor Section service is continued from Fluid Section repair.
y
Inspect and replace old parts with new parts as necessary. Look
y
for deep scratches on metallic surfaces, and nicks or cuts in “O” rings. Take precautions to prevent cutting “O” rings upon installation.
y
Lubricate “O” rings with Key-Lube.
y
Do not over-tighten fasteners. Refer to torque speci cation
y
block on view. Re-torque fasteners following restart.
y
PILOT VALVE DISASSEMBLY
Remove (104) retaining ring.
1. Remove (123) screws and (122) “O” rings.
2. Remove (118) piston rod, (121) sleeve bushing, (119) “O” rings
3. and (120) spacers from the (101) motor body. Remove (103) sleeve and (102) “O” rings.
4.
PILOT VALVE REASSEMBLY
Replace two (102) “O” rings, if worn or damaged, and reinstall
1. (103) sleeve. Install one of the (121) sleeve bushings, (119) “O” rings, (120)
2. spacers and the remaining (121) bushing. Carefully push (118) pilot rod into bushings etc. and retain on
3. each end with the two (122) “O” rings. Retain with (123) screws. Replace (104) retaining rings.
4.
MAJOR VALVE DISASSEMBLY
1.
Remove (107) plate and (108 and 117) gaskets.
2.
On the side opposite the air inlet, push on the inner diameter of (111) spool. This will force the (109) piston out. Continue pushing the (111) spool and remove. Check for scratches and gouges.
3.
Reach into the air section (exhaust side) and remove (116) spacer, (115) spacers, (113) “O” rings, (114) “O” rings, (112) wash­ers. etc. Check for damaged “O” rings.
MAJOR VALVE REASSEMBLY
1.
Replace (112) washer, (114) “O” ring and (113) “O” ring onto (115) spacer and insert etc. NOTE: Be careful to orient spacer legs
away from blocking internal ports.
2.
Lubricate and carefully insert (111) spool.
3.
Install (117) gasket and (107) plate.
4.
Lubricate and install (110) packing cup and insert (109) piston into (air inlet side) cavity. The (110) packing cup lips should point outward.

TROUBLE SHOOTING
Check for kinked (restrictive) outlet material hose.
y
Check for kinked (restrictive) or collapsed inlet material hose.
y
Check for pump cavitation - suction pipe should be sized at
y
least as large as the inlet thread diameter of the pump for proper  ow if high viscosity  uids are being pumped. Suction hose must be a non-collapsing type, capable of pulling a high volume. Check all joints on the inlet manifolds and suction connections.
y
These must be air tight. Inspect the pump for solid objects lodged in the diaphragm
y
chamber or the seat area.
