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 is compatible with the Ni-

trile "O" rings 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

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.

Provide a clean work surface to protect sensitive internal moving

parts from contamination from dirt and foreign matter during service

disassembly and reassembly.

MAINTENANCE CONTINUED

Keep good records of service activity and include pump in preven-

tive 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

1. Remove top manifold(s).

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

3. Remove (15) fluid caps.

NOTE: Only PTFE diaphragm models use a (7) primary diaphragm and

an (8) backup diaphragm. Refer to the auxiliary view in the Fluid Section

illustration.

4. Remove the (6) nut, (7) or (7 / 8) diaphragms and (5) washers.

5. Remove (3 and 4) "O" rings.

NOTE: Do not scratch or mar the surface of (1) diaphragm rod.

FLUID SECTION REASSEMBLY

Reassemble in reverse order.

Clean and inspect all parts. Replace worn or damaged parts with

new parts as required.

Lubricate (1) diaphragm rod and (2) "O" ring with Key-LubeR

grease.

Use ARO PN / 98930-T Bullet (installation tool) to aid in installation

of (2) "O" ring on (1) diaphragm rod.

Be certain (7) or (7 / 8) diaphragm(s) align properly with (15) fluid

caps before making final torque adjustments on bolt and nuts to

avoid twisting the diaphragm.

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

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

ter body. Install the PTFE Diaphragm with the side marked "FLUID

SIDE" towards the fluid cap.

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

while.
