y

all wetted parts to assure compatibility before using
with solvents of this type.

CAUTION

Verify the chemical compatibility of the
pump wetted parts and the substance being pumped,
flushed or recirculated. Chemical compatibility may
change with temperature and concentration of the
chemical(s) within the substances being pumped,
 ushed or circulated. For speci c  uid compatibility,
consult the chemical manufacturer.

CAUTION

Maximum temperatures are based on
mechanical stress only. Certain chemicals will signi ­cantly reduce maximum safe operating temperature.
Consult the chemical manufacturer for chemical com­patibility and temperature limits. Refer to PUMP DATA

CAUTION

Be certain all operators of this equipment
have been trained for safe working practices, under­stand it’s limitations, and wear safety goggles / equip­ment when required.

CAUTION

Do not use the pump for the structural sup­port of the piping system. Be certain the system com­ponents are properly supported to prevent stress on
the pump parts.
Suction and discharge connections should be flex-

y

ible connections (such as hose), not rigid piped,
and should be compatible with the substance being
pumped.

CAUTION

Prevent unnecessary damage to the pump.
Do not allow pump to operate when out of material
for long periods of time.
Disconnect air line from pump when system sits idle

y

for long periods of time.

CAUTION

GENERAL DESCRIPTION

The ARO U.L. listed pump for pumping petroleum products,
offers high volume delivery even at low air pressures and
easy self-priming. This model is designed specifically for
transfer, bulk unloading or fueling applications. It includes a
pressure relief valve (per U.L. Speci cation 79) which restricts
the  uid outlet pressure to under 50 p.s.i. (3.4 bar). The relief
valve can be plumbed to return the bleed o fuel to the stor­age container.

AIR AND LUBE REQUIREMENTS

WARNING

and property damage. The air supply must be limited
to 50 p.s.i.g. (3.4 bar) maximum inlet air pressure.

The air supply line or hose to the pump should be ad-

y

equately sized to carry a sufficient volume of air to the
pump. The material inlet supply tubing should not be too
small or restrictive which will inhibit material flow. The
outlet material volume is governed not only by the air
supply but also by the material volume available at the
inlet.
Air supply provided should be filtered to provide clean

y

dry air. 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

y

with the “O” rings and seals in the air motor section of the
pump.

EXCESSIVE AIR PRESSURE. Can cause pump

INSTALLATION

IMPORTANT

Requirements for the installation are included in the

y

Flammable and Combustible Liquids Code, NFPA No. 30,
Automotive and Marine Service Station Code, NFPA No.
30A and the National Electric Code, ANSI / NFPA No. 70.
A  uid return hose which is compatible with the  uid be-

y

ing pumped must be installed to the relief valve on the
outlet manifold to return  uid back to the supply tank or
pump inlet.
The pump must be grounded to prevent static discharge.

y

Grounding may be accomplished through the legs or to
the ground lug provided on the pump.

Notice that the material inlet / outlet manifolds may be

y

removed and rotated 180° to facilitate various mounting
applications.
If the body of the pump must be rotated, remove the end

y

covers and manifolds and index it so the bolts line up
properly. NOTE: The arrow on the end caps must always
point upward for optimum performance.
When the diaphragm pump is used in a force-feed situa-

y

tion, it is recommended that a check valve be installed at
the air inlet to keep material out of air line in the event of
diaphragm failure.
Secure diaphragm pump legs to a suitable surface to in-

y

sure against damage by excessive vibration.

OPERATING INSTRUCTIONS

The pump should never be operated at pressures exceed-

y

ing 50 p.s.i.g. (345 kPa) inlet air pressure. This pump is
equipped with a pressure relief valve on the material out­let manifold which will open at 40 +/-4 p.s.i. (2.76 bar) to
relieve pressure increases in the outlet hoses / plumbing
caused by thermal expansion or other external forces.
Disconnect the air supply from the pump if it is to be in-

y

active for a few hours.

MAINTENANCE

Refer to the part views and descriptions as provided on
pages 4 through 7 for parts identi cation and service kit in­formation.

Certain ARO “Smart Parts” are indicated which should be

y

available for fast repair and reduction of down time.
Service kits are available to service two separate

y

diaphragm pump functions: 1. AIR SECTION, 2. FLUID
SECTION. The Fluid Section is divided further to match
typical active Material Options.
Provide a clean work surface to protect sensitive internal

y

moving parts from contamination from dirt and foreign
matter during service disassembly and reassembly.
Keep good records of service activity and include the

y

pump in preventive maintenance program.
Before disassembling, empty captured material in the

y

outlet manifold by turning the pump upside down to
drain material from the pump.
