ARO Ingersoll-Rand PX10P-FPS Series Operator's Manual

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 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 pres

sure and will stop cycling once maximum line pressure is reached (dis

pensing 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 lubrication 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

Nitrile 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 diameter as the

pump inlet manifold connection.

Material supply hose must be reinforced, non collapsible type com

patible with the material being pumped.

Piping must be adequately supported. Do not use the pump to sup

port the piping.

Use flexible connections (such as hose) at the suction and dis

charge. 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 insure 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. Ex

haust hose must be conductive and grounded.

Flooded suction inlet pressure must not exceed 10 p.s.i.g. (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 SEC

TION 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 preven

tive maintenance program.

Before disassembling, empty captured material in the outlet man

ifold by turning the pump upside down to drain material from the

pump.

FLUID SECTION DISASSEMBLY

1. Remove (60) inlet manifold, (61) outlet manifold.

2. Remove (22) balls, (19 and 33) O" rings and (21) seats.

3. Remove (15) fluid caps.

NOTE: Only Teflon 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 Lubriplate

FML 2 grease (94276 grease packet is included in service kit).

For models with Teflon diaphragms: Item (8) Santoprene diaphragm

is installed with the side marked AIR SIDE" towards the pump cen

ter body. Install the Teflon diaphragm (7) with the side marked

FLUID SIDE" towards the (15) fluid cap.

Re check torque settings after pump has been re started and run a

while.
