MAINTENANCE
Refer to the part views and descriptions as provided on
pages 4 through 7 for parts identi cation and service kit in-
formation.
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 dia-
phragm pump functions: 1. AIR SECTION, 2. FLUID SEC-
TION. The Fluid Section is divided further to match typical
part Material Options.
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 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.
FLUID SECTION DISASSEMBLY
Remove (61) outlet manifold and (60) inlet manifold.
Remove (22) balls, (19) “O” rings, (21) seats and (76) seat
plugs.
Remove (15 and 15a)  uid caps.
Remove the (14) cap screw, (6) diaphragm washer, (7) dia-
phragm, (5) backup washer and (196) cushion.
NOTE: Do not scratch or mar the surface of (1) diaphragm
rod.
FLUID SECTION REASSEMBLY
SERVICE NOTE: ARO pn 204214-T diaphragm assembly tool is
recommended for use when reassembling the pump.
Reassemble in reverse order. Refer to the torque require-
ments 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” cups with Lu-
briplate® FML-2 grease (94276 grease packet is included
in service kit).
Apply 1/4” wide x 1/8” thick (approximately 46” long)
expandable PTFE Joint Sealant to air cap (item 68 only)
diaphragm bead groove. Use ONLY 1 wrap of sealant. DO
NOT overlap seam. Fill seam with heavy duty anearobic
sealant. Seam to be located between bolt positions 1 and
3 (refer to “Torque Sequence” diagram, page 5).
Re-check torque settings after the pump has been re-
started and run a while.

GENERAL DESCRIPTION
The ARO diaphragm pump o ers high volume delivery even
at low air pressure and a broad range of material compatibil-
ity 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 dif-
ferential 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 maxi-
mum line pressure is reached (dispensing device closed) and
will resume pumping as needed.
AIR AND LUBE REQUIREMENTS
WARNING
EXCESSIVE AIR PRESSURE. Can cause 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.
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 in-
active for a few hours.
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 col-
lapse.
When the diaphragm pump is used in a forced-feed
( ooded inlet) situation, it is recommended that a “check
valve” be installed at the air inlet.
Secure the diaphragm pump legs to a suitable surface to
insure against damage by vibration.
