SAFETY INSTRUCTIONS
To ensure safe and efficient operation, it is essential to read and follow each of these warnings
and precautions.
1. DO NOT smoke near pump or use pump near an open flame. Fire could result.
2. Disconnect power to pump before servicing pump.
3. Turn off the switch before connecting power.
4. Take motors needing service to an authorized repair shop or return to factory to maintain.
5. A filter should be used on pump outlet to ensure that no foreign material is transferred to fuel
tank.
6. Tank or barrel should be anchored to prevent tipping in both the full and empty conditions.
WARNING:
1. Electrical wiring should be done by a licensed electrician in compliance with local codes.
Rigid conduit should be used and proper ground must be provided to avoid the possibility
of electrical shock. Failure to comply with this warning could result in serious injury and/or
loss of property.
2. This product should not be used for fluid transfer into aircraft. This product is not suited for
use with fluids for human consumption or fluids containing water.
3. Extreme operating conditions with working cycles longer than 30 minutes can cause the
motor temperature to rise, thus damaging the motor itself. Each 30-minute working cycle
should always be followed by a 30-minute power-off cooling phase.
GENERAL DESCRIPTION
These products are positive displacement, rotary vane pumps. Depending on installation and
viscosity, these pumps can deliver up to 8 GPM or 30LPM. Their rugged design makes for a
long life of dependability.

FLUID COMPATIBILITY
These products are compatible with the following fluids:
Diesel, Kerosene, Mineral Spirits
CAUTION: DO NOT use with other fluids without consulting manufacturer.
CAUTION: DO NOT use with gasoline.
INSTALLATION INSTRUCTIONS
1.
Tightly screw suction pipe into inlet coupling of pumping unit. Extend suction pipe into truck
tank or barrel to within 3in. of tank bottom.
2.
Screw inlet coupling of pump into 2in. tank or barrel opening. Inlet coupling must be
completely and securely threaded into an undamaged tank or barrel bung.
3.
During installation and maintenance, make sure that the electric supply lines are not live.
4.
Always turn off the switch before supplying electrical power.
5.
Check the correct rotation direction of the DC pump. If it is inverted, check the polarity of
the connection cable.
a)
RED cable: positive pole (+)
b)
BLACK cable: negative pole (-)
6.
Systems should be designed to require a minimum amount of suction lift. Maximum
“equivalent feet of lift” is 8 feet for diesel fuel.
7.
Tank or barrel must be properly vented. A water separator should be used for pumping
diesel fuel.
8.
Power to the unit should be supplied from a dedicated 30 Amp circuit breaker. No other
equipment should be powered from this breaker. If two pumps are supplied from one
breaker, that breaker must be capable of handing the load of both motors.
PROBLEMS AND SOLUTIONS
Problem
Possible Cause
Lack of electric power
The motor is not turning
Rotor jams
Corrective Action
Check the electrical connections
and the safety systems
Check for possible damage or
obstruction of the rotating
components.
Motor problems
Contact with the service department
Low level in the suction tank
Refill the tank
Foot valve blocked
Clean and/or replace the valve
Filter clogged
Clean the filter
Excessive suction pressure
Lower the pump with respect to the
level
High loss of head in the circuit
Use shorter tubing or of greater
(working with the by-pass
diameter
open)
Low or no flow rate
By-pass valve blocked
Dismantle the valve, clean and/or
replace it
Air entering the pump or the
suction tubing
Check the seals of the connections
A narrowing in the suction
Tubing
Use tubing suitable for working
under suction pressure
Low rotation speed
Check the voltage at the pump.
Adjust the voltage and/or use
cables of greater cross-section
The suction tubing is resting on
Raise the tubing
the bottom of the tank
Increased pump noise
Leakage from the pump
body
Cavitations occurring
Reduce suction pressure
Irregular functioning of the
by-pass
Dispense until the air is purged
from the circuit
Air present in the diesel fuel
Verify the suction connections
Seal damaged
Check and replace the mechanical
seal
Daily Use
•
If using flexible tubing, attach the ends of the tubing to the tanks. In the absence of an
appropriate slot, solidly grasp the delivery tube before beginning dispensing.
•
Before starting the pump make sure that the delivery valve is closed (dispensing nozzle or
line valve).
•
Turn the ON/OFF switch to ON. The by-pass valve allows functioning with the delivery
closed for only brief periods.
•
•
•
Open the delivery valve, solidly grasping the end of the tubing.
Close the delivery valve to stop dispensing.
When dispensing is finished, turn off the pump.
MAINTENANCE
Under normal working conditions, the noise emission from all models does not exceed the value
of 80db at a distance of 1 meter from the electric pump.

WARNING
Some dust created by power sanding, sawing, grinding, drilling, and other construction activities
contains chemicals known to the State of California to cause cancer, birth defects or other
reproductive harm. Some examples of these chemicals are:
• lead from lead-based paints,
• crystalline silica from bricks and cement and other masonry products, and
• arsenic and chromium from chemically treated lumber.
Your risk from these exposures varies, depending on how often you do this type of work. To reduce
your exposure to these chemicals: work in a well-ventilated area, and work with approved safety
equipment, such as those dust masks that are specially designed to filter out microscopic particles.
