H.4 CONNECTING THE TUBING
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
diesel fuel and the line accessories installed can create back pressure
greater than the
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
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.
•
•
•
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.
- Minimum recommended nominal diameter:
- Nominal recommended pressure:
- Use tubing suitable for functioning under suction pressure

SUCTION TUBING
- Minimum recommended nominal diameter:
- Nominal recommended pressure:

DELIVERY TUBING
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.
PROBLEMS AND SOLUTIONS
M
The curve refers to the following operating conditions:
Fluid:
Temperature:
Suction conditions:
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)
Diesel fuel
20°C
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.
!
WARNING
F.3 WORKING CYCLE
The pumps are designed for continuous use under conditions of maximum back pressure.
! WARNING
Functioning under by-pass conditions is only allowed for brief periods of time
(2-3 minutes maximum).
F.1 ENVIRONMENTAL CONDITIONS
TEMPERATURE:
min. -20°C / max. +60°C
RELATIVE HUMIDITY:
max. 90%
! WARNING
The temperature limits shown apply to the pump components and must be respected
to avoid possible damage or malfunction.
! WARNING
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.
! WARNING
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..
! WARNING
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.
!
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.
!
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.
F.2 ELECTRICAL POWER SUPPLY
Depending on the model, the pump must be supplied by a single-phase alternating
current line whose nominal values are shown in the table in Paragraph E.2 - ELECTRICAL
SPECIFICATIONS..
The maximum acceptable variations from the electrical parameters are:
Voltage: +/- 5% of the nominal value
Frequency: +/- 2% of the nominal value
! WARNING
Power from lines with values outside the indicated limits can damage the
electrical components.
! WARNING
Always check that the revision level of this manual coincides
with what is shown on the identification plate.
