GENERAL DESCRIPTION

The ARO diaphragm pump off ers 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 / fl uid

sections.

Air operated double diaphragm pumps utilize a pressure dif-

ferential in the air chambers to alternately create suction and

positive fl uid pressure in the fl uid chambers, ball checks insure

a positive fl ow of fl uid.

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 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

EXCESSIVE AIR PRESSURE. Can cause

WARNING

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 lu-

brication 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.

INSTALLATION

Verify correct model / confi guration prior to installation.

Retorque all external fasteners per specifi cations prior to

start up.

Pumps are tested in water at assembly. Flush pump with

compatible fl uid prior to installation.

When the diaphragm pump is used in a forced-feed

(fl ooded inlet) situation, it is recommended that a check

valve" be installed at the air inlet.

Material supply tubing should be at least the same diam-

eter as the pump inlet manifold connection.

Material supply hose must be reinforced, non-collapsible

type compatible with the material being pumped.

Piping must be adequately supported. Do not use the

pump to support the piping.

Use flexible connections (such as hose) at the suction

and discharge. 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 fl at) 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. Exhaust hose must be conductive and grounded.

Flooded suction inlet pressure must not exceed 10 p.s.i.g. (0.69

bar).

OPERATING INSTRUCTIONS

Always fl ush 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 identifi cation 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

Section 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 preventive 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

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

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

Remove (15) fl uid caps.

NOTE: Only PTFE 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 Lubri-

plate FML-2 grease (94276 grease packet is included in ser-

vice kit).

For models with PTFE diaphragms: Item (8) Santoprene

diaphragm is installed with the side marked "AIR SIDE"

towards the pump center body. Install the PTFE diaphragm

(7) with the side marked "FLUID SIDE" towards the (15) fl uid

cap.

Re-check torque settings after pump has been re-started

and run a while.
