WARNING
MISAPPLICATION HAZARD. Do not use
models containing aluminum wetted parts with food
products for human consumption. Plated parts can
contain trace amounts of lead.
CAUTION
Verify the chemical compatibility of the
pump wetted parts and the substance being pumped,
flushed or recirculated. Chemical compatibility may
change with temperature and concentration of the
chemical(s) within the substances being pumped,
ushed or circulated. For specic uid compatibility,
consult the chemical manufacturer.
CAUTION
Maximum temperatures are based on me-
chanical stress only. Certain chemicals will signifi-
cantly reduce maximum safe operating temperature.

patibility and temperature limits. Refer to PUMP DATA
on page 1 of this manual.
CAUTION
Be certain all operators of this equipment
have been trained for safe working practices, under-
stand it’s limitations, and wear safety goggles / equip-
ment when required.
CAUTION
Do not use the pump for the structural sup-
port of the piping system. Be certain the system com-
ponents are properly supported to prevent stress on
the pump parts.
ySuction and discharge connections should be flexi-
ble connections (such as hose), not rigid piped, and
should be compatible with the substance being
pumped.
CAUTION
Prevent unnecessary damage to the pump.
Do not allow pump to operate when out of material
for long periods of time.
yDisconnect air line from pump when system sits idle
for long periods of time.
CAUTION
Use only genuine ARO replacement parts to
assure compatible pressure rating and longest service
life.
WARNING

FLUID SECTION REASSEMBLY
SERVICE NOTE: ARO PN 204214-T Diaphragm assembly tool
is recommended for use when reassembling the pump.
yReassemble in reverse order.
yClean and inspect all parts. Replace worn or damaged
parts with new parts as required.
yLubricate (1) diaphragm rod and (144) “U” cups with Lu-
briplate®FML-2 grease (94276 grease packet is included
in service kit).
yBe certain the diaphragm assembly bottoms out on the
(1) rod, back o PTFE diaphragm assembly far enough to
align holes.
yFor models with PTFE diaphragms: Item (8) Santoprene
diaphragm is installed with the side marked “AIR SIDE”
towards the pump center body. Install the (7) PTFE dia-
phragm with the side marked “FLUID SIDE” towards the
uid cap.
yRe-check torque settings after the pump has been

GENERAL DESCRIPTION
The ARO diaphragm pump oers high volume delivery even
at low air pressure and a broad range of material compatibili-
ty 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
ensure 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.
yA 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.
yIf lubricated air is present, make sure that it is compatible
with the Nitrile “O” rings in the air motor section of the
pump.
OPERATING INSTRUCTIONS
yAlways 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.
yDisconnect the air supply from the pump if it is to be in-
active for a few hours.
yThe 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.
yWhen the diaphr agm pump is used in a forced-feed
(ooded inlet) situation, it is recommended that a “Check
Valve”be installed at the air inlet.
ySecure the diaphragm pump legs to a suitable surface to
ensure against damage by vibration.

TROUBLESHOOTING
Product discharged from exhaust outlet.
yCheck for diaphragm rupture.
yCheck tightness of (14) cap screw.
Air bubbles in product discharge.
yCheck connections of suction plumbing.
yCheck “O” rings between intake manifold and uid caps.
yCheck tightness of (14) cap screw.
Motor blows air or stalls.
yCheck (176) check valve for damage or wear.
yCheck for restrictions in valve / exhaust.
Low output volume, erratic ow or no ow.
yCheck air supply.
yCheck for plugged outlet hose.
yCheck for kinked (restrictive) outlet material hose.
yCheck for kinked (restrictive) or collapsed inlet material
hose.
yCheck for pump cavitation - suction pipe should be sized
at 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.
yCheck all joints on the inlet manifolds and suction con-
nections. These must be air tight.
yInspect the pump for solid objects lodged in the dia-
phragm chamber or the seat area.
