H - Hard 440 Stainless Steel
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 differential in
the air chambers to alternately create suction and positive fluid pressure in
the fluid chambers, ball checks insure 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 presĆ
sure and will stop cycling once maximum line pressure is reached (disĆ
pensing device closed) and will resume pumping as needed.

AIR AND LUBE REQUIREMENTS
MAINTENANCE (CONT’D)
S Provide a clean work surface to protect sensitive internal moving
parts from contamination from dirt and foreign matter during serĆ
vice disassembly and reassembly.
WARNING EXCESSIVE AIR PRESSURE. Can cause pump
damage, personal injury or property damage.
S A filter capable of filtering out particles larger than 50 microns
should be used on the air supply. In most applications there is no
lubrication required other than the ``O" ring lubricant which is apĆ
plied during assembly or repair.
S When lubricated air is necessary, supply the air lubricator with a
good grade of SAE 90 wt. non-detergent oilandsetthelubricatorto
a rate not to exceed one drop per minute.
S Keep good records of service activity and include pump in prevenĆ
tive maintenance program.
S Before disassembling empty captured material in the outlet manĆ
ifold by turning the pump upside down to drain material from the
pump.

OPERATING INSTRUCTIONS
1. Remove top manifold(s).
2. Remove (22) balls, (19) ``O" rings and (21) seats.
3. Remove (15) fluid caps.
NOTE: Only PTFE diaphragm models use a primary (7) diaphragm
and a backup (8) diaphragm. Refer to the auxiliary view. Fig.1
4. Remove the (6) nut, (7) or (7/8) diaphragms and (5) washer.
NOTE: Do not scratch or mar the surface of (1) diaphragm rod.
S 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.
S Disconnect the air supply from the pump if it is to be inactive for a
few hours.
S 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 collapse.
FLUID SECTION REASSEMBL
Y
S 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.
SERVICE NOTE: ARO PN 204214-T Diaphragm Assembly Tool isrecĆ
ommended for use when reassembling the pump.
S Reassemble in reverse order.
new parts as required.
S Secure the diaphragm pump legs to a suitable surface to insure
S Clean and inspect all parts. Replace worn or damaged parts with
against damage by vibration.
S Lubricate (1) diaphragm rod and (144) ``U" cup with Lubriplate
FML-2 Grease. (94276 grease packet is included in service kit.)
S Be certain the diaphragm assembly bottoms out on the (1) rod,
back off Teflon Diaphragm assembly far enough to align holes.
S For models with Teflon diaphragms: Item (8) Santoprene diaĆ
phragm is installed with the side marked ``AIR SIDE" towards the

S Re-check torque settings after pump hasbeenre-startedandruna
while.
S Service kits are divided to service two separate diaphragm pump
functions: 1. AIR SECTION, 2. FLUID SECTION. The FLUID SECĆ
TION is divided further to match typical part MATERIAL OPTIONS.

S Re-torque fasteners following restart.
2. Remove (177) snap ring and (107) inlet plug.
3. On the side opposite the air inlet, push on the inner diameter (111)
spool. This will force the (136) piston plug and (109) piston out.
Continue pushing the (111) spool and remove. Check for scratches
or gouges.
S SERVICE TOOLS - To aid in the installation of (168) ``O'' rings onto
the (167) pilot piston, use Tool # 204130-T, available from Aro.

S Check for diaphragm rupture.
Low output volume, erratic flow, or no flow.
S Check air supply.
S Check tightness of diaphragm nut.
Air bubbles in product discharge.
S Check for plugged outlet hose.
S Check for kinked (restrictive) outlet material hose.
S Check for kinked (restrictive) or collapsed inlet material hose.
S Check for pump cavitation - suction pipe should be sized at leastas
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-colĆ
lapsing type, capable of pulling a high vacuum.
S Check all joints on the inlet manifolds and suction connections.
These must be air tight.
S Check connections of suction plumbing.
S Check ``O" rings between intake manifold and fluid caps.
S Check tightness of diaphragm nut.
Motor blows air or stalls.
