GENERAL INFORMATION
The purpose of this manual is to assist you in installing, op-
erating and maintaining your GPI Oil Pump. This pump is a
positive displacement, direct drive pump.
Observe all safety precautions concerning safe handling of
petroleum fluids. Do not use pump with low flash point fluids
(100°F or less).
To ensure safe operation, this pump must be properly grounded.
Care should be taken to ensure proper grounding during initial
installation and after any service or repair procedures. For your
safety, please take a moment to review the warnings below.
Observe precautions against electrical shock when operating
the system. Serious or fatal shock can result from operating
electrical equipment in damp or wet locations.
On 12-volt pumps, inspect external pump wiring regularly
to make sure it is correctly attached to the battery. To avoid
electrical shock, use extra care when connecting the pump
to power.
Avoid prolonged skin contact with petroleum fluids. Use
protective goggles, gloves and aprons in case of splashing
or spills. Change saturated clothing and wash skin promptly
with soap and water.
Observe precautions against electrical shock when servicing
the pump. Always disconnect power before repairing or ser-
vicing. Never apply electrical power to the system when any
of the coverplates are removed.
If using solvent to clean pump components or tank, observe
the solvent manufacturer’s recommendations for safe use
and disposal.
The 115-volt AC pump motors are equipped with thermal
overload protection. If overheated, the pump will shut itself
off. Turn off the pump if this occurs. See Motor Protector
Section for details.
Worn and damaged hoses or nozzles are potential safety
hazards and should be replaced.
Make sure all threaded connections are wrapped with three to
four turns of oil resistant thread tape or pipe thread sealant.
Make sure drums are properly secured to prevent tip over when
full or empty. All tanks must be properly vented.
Installing Pump to a Tank
GPI pumps have a 2 in. NPT connection that can be mounted
directly to a 2 in. female pipe thread on the tank.
1. Clean the tank interior of all dirt and foreign material.
2. Glue sections of suction pipe together and cut it to the
proper length that is required. Suction pipe should extend
2 to 3 inches above bottom of tank.
3. Screw suction pipe into inlet threads of pump base.
4. Insert the suction pipe through the tank bung. Screw pump
into tank bung to secure the pump to the tank. (Figure 1)

INSTALLATION
Both the 12-volt DC and the 115-volt AC pump are compat-
ible with motor oil, gear oil, hydraulic oil, antifreeze (not to
exceed 50% water), ATF and waste oil. Do not use this pump
for dispensing any fluids other than those for which it was
designed. To do so may damage pump components and will
void the warranty.
Do not use the GPI Oil pump with water, acids, brake fluid or
windshield washer fluid.
If in doubt about compatibility of a specific fluid, contact the
supplier of the fluid to check for chemical compatibility with:
• Aluminum
• Brass
• Nitrile Rubber
• Stainless Steel
• Steel
• Zinc Plated Steel
Do not leave the system running without fluids. “Dry running”
can damage the pump.
Do not pump the tank completely dry, as contaminants from
the bottom of the tank may enter the pump.
The following safety alert symbols are used
in this manual.
DANGER indicates a haz-
ardous situation which, if
not avoided, will result in
death or serious injury.
WARNING indicates a haz-
ardous situation which, if
not avoided, could result in
death or serious injury.
CAUTION indicates a haz-
ardous situation which, if
not avoided, may result in
minor or moderate injury.
It is your responsibility to:
• know and follow applicable national, state, and local safety
codes pertaining to installing and operating electrical equip-
ment for use with petroleum fluids.
• insure that all equipment operators have access to adequate
instructions concerning safe operating and maintenance
procedures.

Figure 1
5. To prevent pressure buildup and possible leaks through
the ball valve, make sure the tank is vented.
Installing Discharge Plumbing on
Pump Outlet
1. Install a 90 degree elbow to the pump outlet using oil
resistant pipe sealant.
2. Install the hose and ball valve using oil resistant pipe
sealant on the threads. Tighten securely.
Electrical Installation
Electrical wiring must be done by a licensed electrician.
Shut off all power before connecting wires to motor. Failure
to follow these wiring instructions may result in death or
serious injury from shock, fire or explosion.
115-volt AC Powered Pumps (Models L 5116 & L 5132):
This GPI Oil Pump is factory wired for 115-volt AC. Power to
the unit should be supplied from a dedicated circuit breaker.
If AC extension cords are used, they must be capable of safely
carrying the rated motor current. Use only heavy duty, 3-wire,
grounded extension cords.
NOTE: Many building codes require Ground Fault Circuit
interrupt (GFCI) protection.
Motor Ratings (FLA):
115-volt AC:
1/2 HP, 1725 RPM – 7.5 amps
1 HP, 3450 RPM – 13 amps
12-volt DC:
1/2 HP, 1800 RPM – 40 amps
12-volt DC Powered Pumps (Model L 5016):
This GPI Oil Pump is factory wired for 12-volt DC. Circuit
must be protected with a 50 amp automotive-type fuse (not
supplied).
The power cord is not supplied with the pump. GPI recom-
mends a minimum power cord of 10/3 AWG. Do not exceed
15 feet of cord.
CAUTION
OPERATION
Do not operate pump dry. Damage to pump could occur.
Before first usage, pour oil into pump outlet port to coat
pumping element.
1. Place ball valve into the receiving tank to be filled.
2. Turn on the motor.
3. Open the ball valve and fill the container to the desired
level. If flow does not occur with 15 seconds, shut off motor
and refer to the priming information in the Troubleshooting
Section.
4. Shut off the nozzle.
5. Turn off the motor.
Motor Protector
The AC pumps contain thermal motor protection. If the pump
overheats the unit will shutoff.
If the motor shuts off, follow these instructions:
Model L 5132: Turn off the switch. Allow the motor to cool
before restarting.
Model L 5116: Turn off the switch. Allow the motor to cool.
Push the button to manually reset the protector.
Model L 5016: The 12-volt model is protected by inline fuse
(not supplied). If the motor shuts off, check the fuse.
Disconnect power and relieve pressure in the system by open-
ing the nozzle before servicing the pump.
This pump is designed for minimum maintenance. Motor bear-
ings are sealed and require no lubrication. Inspect the pump
and components regularly for leaks and make sure the hose,
ball valve and components are in good condition.
Use of the pump with unauthorized fluids will void the war-
ranty.
Remove and clean the strainer if low flow is noticed. To clean
the strainer, remove the three screws on the strainer cover.
Remove cover and pull out screen. Clean screen and reinstall.
Care should be taken not to damage the O-ring.
