GENERAL DESCRIPTION

The ARO

diaphragm pump offers high volume delivery even



at low air pressure and a broad range of material compatibili-

ty options are 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 dif-

ferential in the air chambers to alternately create suction and

a positive fluid pressure in the fluid chambers, ball checks

ensure 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 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 pump

WARNING

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.

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 in-

active 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 col-

lapse.

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

ensure 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 the

pump in preventive maintenance program.

Service kits are available to service two separate dia-

phragm pump functions: 1. AIR SECTION, 2. FLUID SEC-

TION. The Fluid Section is divided further to match typical

active Material Options.

Before disassembling, empty captured material in the

outlet manifold by turning the pump upside down to

drain material from the pump.
