dimension).
Under different suction conditions higher pressure values can be created that reduce
the flow rate compared to the same back pressure values.
! WARNING
To obtain the best performance, it is very important to reduce loss of suction
pressure as much as possible by following these instructions: THE MOTORS ARE NOT OF AN ANTI-EXPLOSIVE TYPE.
• Shorten the suction tube as much as possible Do not install them where inflammable vapors can be present.
• Avoid useless elbows or throttling in the tubes
• Keep the suction filter clean
• Use a tube with a diameter equal to, or greater than, indicated (see Installation)

persons and cause pollution.
Loosening of the connections (threaded connections, flanging, gasket seals) can
cause serious ecological and safety problems..
Check all the connections after the initial installation and on a daily basis after that.
Tighten the connections, if necessary.
H.5 CONSIDERATIONS REGARDING DELIVERY AND SUCTION LINES
DELIVERY
The choice of pump model must be made keeping the characteristics of the system in mind.
The combination of the length of the tubing, the diameter of the tubing, the flow rate of the
+/- 5% of the nominal value
diesel fuel and the line accessories installed can create back pressure greater than the
+/- 2% of the nominal value
maximums anticipated such as to cause the (partial) opening of the pump by-pass with the
consequent noticeable reduction of the flow rate supplied.
In such cases, to allow correct functioning of the pump, it is necessary to reduce system
resistance, using shorter tubing and/or of wider diameter and line accessories with less
resistance (e.g., an automatic dispensing nozzle for greater flow rates).
SUCTION
E 80 / E120 pumps are self-priming and characterized by good suction capacity.
During the start-up phase, with an empty suction tube and the pump wetted with fluid, the electric
pump unit is capable of suctioning the liquid with a maximum difference in height of 2 meters.
It is important to point out that the priming time can be as long as one minute and the presence
of an automatic dispensing nozzle on the delivery line prevents the evacuation of air from the
installation, and, therefore, prevents proper priming.
For this reason, it is always advisable to prime the pump without an automatic delivery nozzle,
verifying the proper wetting of the pump. The installation of a foot valve is recommended to
prevent the emptying of the suction tube and keep the pump wet. In this way, the pump will
subsequently always start up immediately.
When the system is functioning, the pump can work with pressure at the inlet as high as
0.5 bar, beyond which cavitation phenomena can begin, with a consequent loss of flow rate
and increase of system noise.
As we have said up to this point, it is important to guarantee low suction pressure by using
short tubing of a diameter equal to or larger than recommended, reducing curves to a

grade IP 55.
I INITIAL START-UP
• Check that the quantity of diesel fuel in the suction tank is greater than the amount you
wish to transfer.
• Make sure that the residual capacity of the delivery tank is greater than the quantity you
wish to transfer.
• Do not run the pump dry. This can cause serious damage to its components.
• Make sure that the tubing and line accessories are in good condition. Diesel fuel leaks
can damage objects and injure persons.
• Always install a suction filter to protect the pump.
• Never start or stop the pump by inserting or removing any plugs.
• Do not operate switches with wet hands.
• Prolonged contact with diesel fuel can damage the skin. The use of glasses and gloves
is recommended.
• Single-phase motors are provided with an automatic thermal protection switch.
! WARNING
Extreme operating conditions can raise the motor temperature and, consequently,
cause the thermal protection switch to stop it.
Turn off the pump and wait for it to cool before resuming use.
The thermal protection automatically turns off when the motor is sufficiently cool.
In the priming phase the pump must blow the air initially present in the entire installation out of
the delivery line.
Therefore it is necessary to keep the outlet open to permit the evacuation of the air.
! WARNING
If an automatic type dispensing nozzle is installed on the end of the delivery line,
the evacuation of the air will be difficult because of the automatic stopping device that
keeps the valve closed when the line pressure is too low.
It is recommended that the automatic dispensing nozzle be temporarily disconnected
during the initial start-up phase.
The priming phase can last from several seconds to a few minutes, as a function of
the characteristics of the system.
If this phase is prolonged, stop the pump and verify:
• That the pump is not running completely dry;
• That the suction tubing is not allowing air to seep in;
•
That the suction filter is not clogged;
•
That the suction height is not greater than 2 meters (if the height is greater than 2 meters,
fill the suction tube with fluid);
• That the delivery tube is allowing the evacuation of the air.
SUCTION:
When priming has occurred, verify that the pump is operating within the anticipated range,
• Foot valve with filter
in particular:
• Rigid and flexible tubing
• Pump suction filter • That under conditions of maximum back pressure, the power absorption of the motor
stays within the values shown on the identification plate;
• That the suction pressure is not greater than 0.5 bar;
• That the back pressure in the delivery line is not greater than the maximum back pressure
anticipated for the pump.
L DAILY USE
a. 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.
b. Before starting the pump make sure that the delivery valve is closed (dispensing nozzle
or line valve).
c. Turn the ON/OFF switch to ON. The by-pass valve allows functioning with the delivery closed
for only brief periods.
d. Open the delivery valve, solidly grasping the end of the tubing.
e. Close the delivery valve to stop dispensing.
f. When dispensing is finished, turn off the pump.
! WARNING
Functioning with the delivery closed is only allowed for brief periods (2-3 minutes
SINGLE PHASE
maximum). After use, make sure the pump is turned off.
TO MOTOR
LACK OF ELECTRIC POWER:
A lack of electric power, with the consequent accidental stopping of the pump, can be caused
by:
- A safety device tripping
- A drop in line voltage
In either case, act as follows:
TO
a. Close the delivery valve
MOTOR
b. Attach the end of the delivery to the slot provided on the tank
c. Turn the ON/OFF switch to the OFF position.
Resume operations as described in Paragraph L - DAILY USE, after determining the cause
of the stoppage.
