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 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 inactive 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 collapse.

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.

Secure the diaphragm pump legs to a suitable surface to insure

against damage by vibration.

MAINTENANCE

Certain ARO Smart Parts" are indicated which should be available

for fast repair and reduction of down time.

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.

Service Kits are available to service two separate Diaphragm Pump

functions: 1. AIR SECTION, 2. FLUID SECTION. The Fluid Section

is divided further to match typical active MATERIAL OPTIONS.

DIAPHRAGM PUMP SERVICE

GENERAL SERVICE NOTES:

Inspect and replace old parts with new parts as necessary. Look for

deep scratches on metallic surfaces, and nicks or cuts in O" rings.

Tools needed to complete disassembly and repair:

7/8" wrench, 1/2" socket or wrench, 3/8" socket or wrench, 3/8"

Allen wrench, 10 mm Allen wrench, T-10 Torx screwdriver,

torque wrench (measuring inch pounds), O" ring pick.

FLUID SECTION DISASSEMBLY

1. Remove (61) top manifold.

2. Remove (19) O" rings, (21) seats, (12) washers (where applicable)

and (22) balls.

3. Remove (60) bottom manifold.

4. Remove (19) O" rings, (21) seats, (12) washers (where applicable)

and (22) balls.

5. Remove (15) fluid caps.

6. Remove (14) bolt, (6) diaphragm washer, (7) or (7 / 8) diaphragms

and (5) washer.

7. Remove (1) connecting rod from air motor.

8. Carefully remove remaining (14) bolt, (6) diaphragm washer, (7) or

(7 / 8) diaphragms and (5) washer from (1) connecting rod. Do not

mar surface of connecting rod.

FLUID SECTION REASSEMBLY

Reassemble in reverse order.

Lubricate (1) connecting rod with LubriplateR or equivalent O" ring

lubricant.

Connecting rod (1) should be installed using 96571 bullet, included

in service kit.

Install (5) washers with i.d. chamfer toward diaphragm.

When replacing Teflon diaphragms, install the 93465 Santoprene di-

aphragm behind the Teflon diaphragm.
