H4 CONNECTING THE TUBING
• Before connection, make sure that the
tubing and the suction tank are free of dirt
and thread residue that could damage the
pump and its accessories.
• Before connecting the delivery tube,
partially fill the pump body with diesel fuel
to facilitate priming.
• Do not use conical threaded joints that
could damage the threaded pump
openings if excessively tightened.
SUCTION TUBING:
- Minimum recommended nominal diameter: 1-1/4” (model E80)
1-1/2” (model E120)
- Nominal recommended pressure: 10 bar
- Use tubing suitable for functioning under suction pressure
DELIVERY TUBING
- Minimum recommended nominal diameter: 1”
- Nominal recommended pressure: 10 bar
ATTENTION
It is the installer's responsibility to use tubing with adequate characteristics.
The use of tubing unsuitable for use with Diesel fuel can damage the pump, injure
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.
H5
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
diesel fuel and the line accessories installed
can create back pressure greater than the
maximums anticipatedsuch 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 minimum and using suction filters of
wide cross-section and foot valves with the
lowest possible resistance.
It is very important to keep the suction filters
clean because, once clogged, they increase
system resistance.
The difference in height between the pump
and the fluid level must be kept as small as
possible and, at any rate, within the 2 meters
anticipated for the priming phase.
If this height is exceeded, it will always be
necessary to install a foot valve to allow for
the filling of the suction tube and provide
tubing of wider diameter. It is recommended
that the pump not be installed at a difference
in height greater than 3 meters.
ATTENTION
In the case that the suction tank is higher than the pump, it is advisable to install an antisiphon valve to prevent accidental diesel fuel leaks.
H7 ELECTRICAL CONNECTIONS
Single-phase motors are supplied with a
bipolar switch and capacitor wired and
installed inside the terminal strip box (see
diagram).
The characteristics of the capacitor are shown on
the identification plate for each pump model.
The switch has the sole function of
starting/stopping the pump and cannot in any
way substitute for the main circuit breaker
provided for in the applicable regulations.
ATTENTION
The pumps are supplied without electrical safety equipment such as fuses, motor protectors,
systems to prevent accidental restarting after power failures or others. It is indispensable to
install an electric panel, upstream from the pump's power supply line, equipped with an
appropriate residual current operated circuit breaker.
It is the installer's responsibility to perform the electrical connections with respect for the
applicable regulations.
• During installation and maintenance, make
sure that the electric supply lines are not live
• Use cables characterized by the
minimum cross-sections, nominal
voltages and wiring-type adequate to the
electrical characteristics shown in
Paragraph E2 - ELECTRICAL SPECIFICATIONS and the installation environment.
• In three-phase motors verify the correct
direction of rotation (see Paragraph R DIMENSIONS AND WEIGHTS)
• All motors are equipped with a ground
terminal to connect to the ground line of
the electrical network.
• Always close the cover of the terminal strip
box before supplying electrical power, after
ascertaining the integrity of the gasket seals
that ensure protection grade IP 55.

C
Suction Conditions The tube and the pump position relative to the fluid level is such
that a pressure of 0.3 bar is generated at the nominal flow rate.
Under different suction conditions higher pressure values can be created that reduce the
flow rate compared to the same back pressure values.
To obtain the best performance, it is very important to reduce loss of suction pressure as
much as possible by following these instructions:
• Shorten the suction tube as much as possible
• 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)
H6 LINE ACCESSORIES
The pumps are furnished without line accessories.
Following is a list of the most common line
accessories whose use is compatible with the
proper functioning of the pumps.

Flexible tubing
SUCTION
Foot valve with filter
Rigid and flexible tubing
Pump suction filter
ATTENTION
It is the installer's responsibility to provide the line accessories necessary for the safe
and proper functioning of the pump.
The use of accessories unsuitable for use with diesel fuel can damage the pump, injure
persons and cause pollution.
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.
ATTENTION
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.
• 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.
SINGLE-PHASE MOTORS
Single-phase motors are supplied with a
pre-existing 2-meter cable with electric plug.
To change the cable, open the terminal strip
cover and connect the line according to the
following diagram:
THREE-PHASE MOTORS
Three-phase motors are supplied with a
terminal strip box and terminal strip.
To connect the electric motor to the electric
power line, open the terminal strip cover
and connect the cables according to the
diagram.
ATTENTION
Verify that the terminal strip blades are positioned according to the diagram provided for the
available power supply voltage. Verify the correct direction of rotation of the motor (see the
paragraph overall dimensions), and, if not correct, invert the connection of the two cables in
the power supply plug or on the terminal strip.
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.
ATTENTION
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 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.
When priming has occurred, verify that the pump is operating within the anticipated range, in
particular:
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.
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:
a. Close the delivery valve
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.
