ATTENTION
The curve refers to the following operating conditions:
Fluid Diesel Fuel
Temperature 20°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)
The burst pressure of the pump is of 20bar.

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.

ATTENTION
In the case that the suction tank is higher than the pump, it is advisable to install an anti-
siphon valve to prevent accidental diesel fuel leaks.

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.
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.
Respect the following (not exhaustive) instructions to ensure a proper electrical installation:
• During installation and maintenance, make direction of rotation (see Paragraph R -

out of the delivery line.
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 cha-
racteristics of the system. If this phase is prolonged, stop the pump and verify:
• That the pump is not running completely • That the suction height is not greater than
