GENERAL DESCRIPTION
MAINTENANCE
The ARO diaphragm pump offers 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 / fluid sections.
Air operated double diaphragm pumps utilize a pressure differen-
tial in the air chambers to alternately create suction and a 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 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.
Refer to the part views and descriptions as provided on pages 4
through 7 for parts identification and service kit information.
Certain ARO “Smart Parts” are indicated which should be avail-
able for fast repair and reduction of down time.
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 Op-
tions.
y
y
Provide a clean work surface to protect sensitive internal mov-
ing parts from contamination from dirt and foreign matter dur-
ing service disassembly and reassembly.
y
Keep good records of service activity and include the pump in
preventive maintenance program.
Before disassembling, empty captured material in the outlet
manifold by turning the pump upside down to drain material
from the pump.
y
y
AIR AND LUBE REQUIREMENTS
WARNING EXCESSIVE AIR PRESSURE. Can cause pump dam-
age, personal injury or property damage.
FLUID SECTION DISASSEMBLY
A filter capable of filtering out particles larger than 50 microns
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
the “O”rings and seals in the air motor section of the pump.
y
y
1. Remove top manifold(s).
2. Remove (22) balls, (19) “O” rings (where 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.
OPERATING INSTRUCTIONS
4. Remove the (14) screw, (6) washer, (7) or (7 / 8) diaphragm and
(5) washer.
NOTE: Do not scratch or mar the surface of (1) diaphragm rod.
Always flush the pump with a solvent compatible with the ma-
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
for a few hours.
The outlet material volume is governed not only by the air sup-
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.
y
FLUID SECTION REASSEMBLY
y
y
Reassemble in reverse order.
Clean and inspect all parts. Replace worn or damaged parts
with new parts as required.
y
y
Lubricate (1) diaphragm rod and (2) “O” ring with Key-Lube “O”
ring lube.
Use ARO pn / 98931-T bullet (installation tool) to aid in installa-
tion of (2) “O”ring on (1) diaphragm rod.
Be certain (7) or (7 / 8) diaphragms align properly with (15) fluid
caps before making final torque adjustments on bolt and nuts
to avoid twisting the diaphragms.
y
y
y
When the diaphragm pump is used in a forced-feed (flooded
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
against damage by vibration.
y
y
For models with PTFE diaphragms: Item (8) Santoprene dia-
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 fluid cap.
Re-check torque settings after the pump has been re-started
and run a while.

2. Install one of the (121) sleeve bushings, (119) “O” rings, (120)
spacers and the remaining (121) bushing.
3. Carefully push (118) pilot rod into bushings etc. and retain on
each end with the two (122) “O”rings. Retain with (123) screws.
4. Replace (104) retaining rings.
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.
Inspect and replace old parts with new parts as necessary. Look
for deep scratches on metallic surfaces, and nicks or cuts in “O”
rings.
Take precautions to prevent cutting “O”rings upon installation.
Lubricate “O”rings with Key-Lube.
Do not over-tighten fasteners. Refer to torque specification
block on view.
Re-torque fasteners following restart.

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) wash-
ers. etc. Check for damaged “O”rings.

TROUBLE SHOOTING
Product discharged from exhaust outlet.
Check for kinked (restrictive) outlet material hose.
y
y
y
Check for diaphragm rupture.
Check for kinked (restrictive) or collapsed inlet material hose.
Check for pump cavitation - suction pipe should be sized at
least as large as the inlet thread diameter of the pump for
proper flow if high viscosity fluids are being pumped. Suction
hose must be a non-collapsing type, capable of pulling a high
volume.
y
y
Check tightness of (14) diaphragm screw.
Air bubbles in product discharge.
Check connections of suction plumbing.
Check “O”rings between intake manifold and fluid caps.
Check tightness of (14) diaphragm screw.
y
y
y
Check all joints on the inlet manifolds and suction connections.
These must be air tight.
Inspect the pump for solid objects lodged in the diaphragm
chamber or the seat area.
y
y
Low output volume, erratic flow or no flow.
Check air supply.
Check for plugged outlet hose.
