OPERATING INSTRUCTIONS
y
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.
y
Disconnect the air supply from the pump if it is to be in-
active for a few hours.
y
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.
MAINTENANCE
y
This product is not intended to be repairable. However,
some service items are available.
y
Provide a clean work surface to protect sensitive internal
moving parts from contamination from dirt and foreign
matter during service disassembly and reassembly.
y
Keep good records of service activity and include the
pump in preventive maintenance program.
y
At the end of its service life, please dispose of pump and
contents properly.
GENERAL DESCRIPTION
The ARO diaphragm pump oers high volume delivery even
at low air pressures, easy self priming and the ability to pump
various viscosity materials. The pump is designed to corre-
spond to the needs of the user by oering a variety of wetted
parts congurations to handle almost any application.
Air operated double diaphragm pumps utilize a pressure
dierential in the air chambers to alternately create suction
and positive uid pressure in the uid chambers. Flat checks
insure a positive ow of 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.
The Acetal material used in this pump contains stainless steel
bers. It’s conductivity allows it to be connected to a suitable
ground. A ground screw is provided for this.
AIR AND LUBE REQUIREMENTS
WARNING
EXCESSIVE AIR PRESSURE. Can cause pump
damage, personal injury or property damage.
y
A filter capable of filtering out particles larger than 50
microns should be used on the air supply. In most ap-
plications there is no lubrication required other than the
“O” ring lubricant which is applied during assembly or repair.
y
The pump, when tted with ex checks, can be rotated
360° to suit the application. It may be mounted upside
down or on the wall with no eect on suction lift or op-
erating eciency. The lter and regulator need to be ori-
ented in a normal vertical direction to function properly.
y
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
y
Apply PTFE tape or pipe sealant to threads upon assem-
bly to prevent leakage.
y
Secure the diaphragm pump legs to a suitable surface to
insure against damage by vibration.
y
When the diaphragm pump is used in a forced-feed
(ooded inlet) situation, it is recommended that a “Check
Valve” be installed at the air inlet.
