GENERAL DESCRIPTION
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 dif-
ferential in the air chambers to alternately create suction and
positive fluid pressure in the fluid chambers, ball checks en-
sure 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 maxi-
mum line pressure is reached (dispensing device closed) and
will resume pumping as needed.
AIR AND LUBE REQUIREMENTS
EXCESSIVE AIR PRESSURE. Can cause
WARNING
pump damage, personal injury or property damage.
A filter capable of filtering out particles larger than 50
microns should be used on the air supply. There is no lu-
brication required 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.

INSTALLATION

Verify correct model / configuration prior to installation.
Retorque all external fasteners per specifications prior to
start up.
Pumps are tested in water at assembly. Flush pump with
compatible fluid prior to installation.
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.
Material supply tubing should be at least the same diam-
eter as the pump inlet manifold connection.
Material supply hose must be reinforced, non-collapsible
type compatible with the material being pumped.
Piping must be adequately supported. Do not use the
pump to support the piping.
Use flexible connections (such as hose) at the suction
and discharge. These connections should not be rigid
piped and must be compatible with the material being
pumped.
Secure the diaphragm pump legs to a suitable surface
(level and flat) to ensure against damage by vibration.
Pumps that need to be submersed must have both wet
and non-wet components compatible with the material
being pumped.
Submersed pumps must have exhaust pipe above liquid
level. Exhaust hose must be conductive and grounded.
Flooded suction inlet pressure must not exceed 10 psig (0.69
bar).

OPERATING INSTRUCTIONS

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.
Disconnect the air supply from the pump if it is to be inactive
for a few hours.
PARTS AND SERVICE KITS
Refer to the part views and descriptions as provided on page 4
through 7 for parts identification and Service Kit information.
Certain ARO "Smart Parts" are indicated which should be
available 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
Options.

MAINTENANCE

Provide a clean work surface to protect sensitive internal
moving parts from contamination from dirt and foreign
matter during service disassembly and reassembly.
Keep good records of service activity and include 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.
FLUID SECTION DISASSEMBLY
1.
Remove (61) outlet manifold, (60) inlet manifold.
2.
Remove (22) balls, (19 and 33) "O" rings 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. Remove the (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
Reassemble in reverse order. Refer to the torque requirements
on page 5.
Clean and inspect all parts. Replace worn or damaged
parts with new parts as required.
Lubricate (1) diaphragm rod and (144) "U" cup with Lubri-
plate FML-2 grease (94276 grease packet is included in ser-
vice kit).
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.
Check torque settings after pump has been re-started
and run a while.
