CAUTION
WARNING
You are now the owner of a Goulds pump. This pump
was carefully inspected and subjected to final tests before
releasing for shipment. In order to assure maximum
performance please follow the simple instructions in this
manual.
PUMPING OF VOLATILE PETROLEUM
PRODUCTS CAN BE HAZARDOUS.
FOR THIS REASON, EXTREME CARE MUST BE
EXERCISED AND ALL OPERATING AND SAFETY
INSTRUCTIONS STRICTLY ADHERED TO. FAILURE
TO DO THIS CAN RESULT IN A FIRE OR EXPLOSION.
APPLICATION: This pump is designed to pump petroleum products such as diesel fuel, jet fuel or gasoline
in well-ventilated areas that do not contain potentially
explosive fumes.
This equipment should be operated only by personnel
who have been thoroughly instructed as to the hazards
involved and who are familiar with the following operating and safety instructions.
OPERATING AND SAFETY INSTRUCTIONS
1. Use non-sparking tools when making pump connec-
tions.
2. Always securely connect the ground wire to a good
ground on the tank being filled, before operating the
pump.
3. Do not operate the engine while filling the pump
tank with its initial priming liquid.
4. Do not refill engine if running or hot.
5. Do not pump liquids other than water or petroleum
products.
6. Do not operate with leaky seal or piping, closed suc-
tion or discharge valve or with a fill plug removed.
7. Operate pump only with guard in place.
MAINTENANCE INSTRUCTIONS
1. If engine is hard to start, or runs rough, move unit to
a safe area and check out on water.
2. This engine must be maintained in original condition
throughout its use. Prior to each use, inspect the air
cleaner, spark arresting muffler, shielded spark plug,
shielded spark plug wire, and the enclosed run-stop
switch, to make certain that these are not worn or
damaged in any way.
3. Use only original replacement parts - this is critical
since each part was selected for its safety and high
quality.
RECOMMENDED PRECAUTIONS
1. APPLICATION: This pump is designed to pump
petroleum products such as diesel fuel, jet fuel or
gasoline in well-ventilated areas that do not contain
potentially explosive fumes. Primarily intended for
fuel transfer or refueling construction equipment at
remote open air sites where the lack of electricity
makes it impossible to use pumps driven by explosion-proof electric motors.
Pumping of volatile petroleum products can be haz-
ardous. For this reason, extreme care must be exercised and all operating and safety instructions strictly
adhered to.
2. As with all self-priming centrifugal pumps, the pump
tank must be initially filled with the liquid being
pumped. DO NOT run the engine while filling the
pump tank. Failure to follow this precaution could
result in a fire or explosion.
3. This pump is designed primarily for water and petroleum products use. Before pumping other liquids,
carefully read the special note below.
4. Do not subject the pump to a pressure in excess of 75
psi.
5. Should the fluid temperature rise more than 50ºF.
ambient, expansion joints must be installed on both
the suction and discharge ports to relieve any stress
on the pump casing.
6. No modifications, additions or deletions should be
made to the pump.
7. Prime movers powering the pumps may operate
at high temperatures. Keep hands off mufflers and
manifolds to avoid burns.
8. In systems where shock wave pressures may be generated, protective devices (check valve/gate valve, etc.)
must be installed on discharge line to prevent shock
wave pressures from entering casing. A discharge
check valve is required when operating against high
static heads.
9. Do not refill engine fuel tank while power unit is
running or while hot. Prevent splashing of gasoline or
other fuel while filling supply tank.
10. Do not use in a combustible atmosphere.
11. Make daily checks of the tightness of suction and
discharge pipe, drain, filler plug and pump gaskets.
Check tightness of gasoline tank filler cap each time
tank is filled. Operation should not proceed until all
of the above items have been checked and are tight.
The performance of Goulds Water Tech-
nology is based upon clear, cold, fresh water with suction conditions as shown on the performance
curve. If used to pump other liquids, pump performance
may differ from rated performance based on the different specific gravity, temperature, viscosity, etc. of the
liquid being pumped. However, a standard pump may
not be safe for pumping all types of liquids, such as toxic,
volatile or chemical liquids, or liquids under extreme
temperatures or pressures. Please consult your Goulds
Water Technology catalog as well as local codes and general references to determine the appropriate pumps for
your particular application. Since it is impossible for us
to anticipate every application of a Goulds pump, if you
plan to use the pump for other than a water or petroleum
product application, consult Goulds Water Technology
beforehand to determine whether such application may
be proper or safe under the circumstances. Failure to do
so could result in property damage or personal harm.

OPERATING INSTRUCTIONS
GENERAL
• Our shipping container has been specifically designed
to prevent transit damage. However, any indications of
damage or shortage should be carefully noted on the delivery ticket and a claim filed promptly with the carrier.
PROPER LOCATION
• By placing your Goulds pump on a firm, level foundation, you reduce the chance of its falling into the liquid
and damaging the engine. You also insure proper oil
lubrication of the engine and obtain optimum engine
performance. Best pump operation is obtained by locating the pump so as to minimize the suction lift as much
as practical, keeping in mind that a pump can push
liquid more effectively than it can pull or draw liquid.
CONNECTIONS
• Connections at the easily accessible suction and discharge ports can be made with either oil-resistant hose
or pipe. The use of strongly reinforced suction hose will
prevent collapsing of the hose during operation. New
hose washers should be used at the couplings to prevent
trouble-causing leaks. Pipe joint compound that will not
dissolve in the liquid being pumped should be used on
all pipe joints. All hose or pipe should be independently
supported to eliminate excessive strain on the pump.
For best results your hose should discharge higher than
the pump to prevent siphoning action when the unit is
shut down.
• We strongly recommend the use of extra-heavy close
faced nipples on the suction and discharge ports of
the 2AM32-P petroleum pump. Also, be sure to apply
pipe compound on the nipples before installing. When
pumping petroleum products, it is particularly important to use suitable hose, gaskets and fittings to minimize the chance of a leak occurring.
• Also, be certain that the splash guard special air cleaner
and spark arresting muffler are used on every application.
STRAINER ADVISABLE
• Protect your investment, use a strainer. Strainers are attached to the suction line to prevent stones and foreign
debris from damaging the impeller or diffuser, resulting in reduced performance. Stones lodged inside the
pump can cause premature wear and poor performance.
To keep the strainer from working into the sediment,
suspend the hose from the end of a rope. If you do not
have a strainer, your Goulds Water Technology dealer
can supply one in the correct size.
STARTING
• Follow the engine manufacturer’s instructions carefully.
Fill the pump tank with liquid before starting.
• Your pump has been designed to prime itself in a few
minutes with the engine running fast. High suction lifts
require additional time and reduce the performance
of the pump. Should you have difficulty, refer to the
Troubleshooting Guide section.
• Goulds Water Technology prime and reprime themselves providing the tank is filled with liquid. Should
you lose this liquid from the tank accidentally or by
4
draining purposely, it will be necessary to refill it with
liquid before starting. DO NOT operate the engine
while filling the pump tank with its initial priming
liquid.
LUBRICATION
• The latest engineering advancements have been incorporated into our self-lubrication shaft seal. The liquid
being pumped cools and lubricates the seal. Running
the pump dry will damage the seal. Always keep liquid
in the tank, and no further lubrication of the pump end
is necessary. Refer to engine manual for proper engine
lubrication.
• It is particularly important when pumping petroleum
products to regularly check the condition of the seal. At
the first sign of a leak in the seal, the unit should be shut
down immediately and the seal replaced with a new one
of the same design.
HIGH DISCHARGE
• If you have a vertical discharge line rising 30 feet or
more, your pump is subject to severe back pressures
when it is shut down. This back pressure can cause
damage to the pump. To prevent the possibility of this
damage, install a check valve on the discharge line as
near to the pump as possible, and the shock will be
stopped at the valve.
MAINTENANCE
1. The pump is fitted with a mechanical shaft seal which
requires no other lubrication than the liquid in which
it operates.
2. On occasion, the mechanical shaft seal may become
worn and must be replaced. Follow the replacement
instructions enclosed with each seal assembly. Do not
operate with a leaky seal.
3. When pump is not in use for several days, or for winter storage, drain all the liquid from the tank.
4. Follow the engine manufacturer’s manual for periodic
maintenance and adjustment. Also follow their procedure for winterizing the engine as set forth in the
manual.
5. Storage of engine requires rotation of engine shaft to
the compression stroke, thus inhibiting rust on the
engine valves.
6. Maintenance and functional problems relating to the
engine should be referred directly to the manufacturer’s service station.
7. This engine is modified by:
a. An Air Maze air cleaner, with oil-wetted metallic
element. A small amount of engine oil should be
added per instruction label on the outside of the
air cleaner.
b. A spark arresting muffler, centrifugal type. It must
be mounted with the clean-out plug at the bottom. Carbon particles should be removed through
the clean-out hole on a regular basis. Do this only
when engine is cold and in a well-ventilated area
free from petroleum vapors.
c. A shielded spark plug and shielded spark plug wire.
d. An enclosed run-stop switch on the side of the
engine shroud.
