WARNING
The curve refers to the following operating conditions:
Fluid: PETROL,
Temperature: 20° C
Suction conditions: The pipe and the pump position
relative to the uid level is such that a low pressure of
0.3 bar is generated at the nominal ow rate.
Under dierent suction conditions higher low pressure
values can be created that reduce the ow rate compared
to the same back pressure values. To obtain the best perfor-
mance, it is very important to reduce loss of suction pres-
sure as much as possible by following these instructions:
• shorten the suction pipe as much as possible
• avoid useless elbows or throttling in the pipes
• keep the suction lter clean
• use a pipe with a dia meter equal to, or greater than,
indicated (see Installation).

L1 POSITIONING, CONFIGURATIONS AND
ACCESSORIES
NOTICE
The pump must be secured in a stable manner.
WARNING
It is the installer's responsibility to provide the line acces-
sories necessary for the safe and proper functioning of the
pump. The accessories that are not suitable to be used with
the previously indicated material could damage the pump
and/or cause injury to persons, as well as causing pollution.
To maximise performance and prevent damage that could
affect pump operation, always demand original accessories.
L2 NOTES ON SUCTION AND
DELIVERY LINES
DELIVERY
The selection of the pump model must be made taking into account the characteristics of the system.
The combination OF: the length of the pipe, the diameter of the pipe, as well as the accessories installed,
could create back pressure that are greater than the maximum predicted pressure, thereby causing the
pump's electronic controls to intervene and reducing the dispensed flow considerably.
In these cases, to guarantee correct operation of the pump, it is necessary to reduce the resistance of
the system using pipes that are shorter or that have a greater diameter, as well as line accessories with
smaller resistances (e.g. an automatic dispensing nozzle with greater ow rate capacity).
SUCTION
Self-priming pumps are characterized by excellent suction capacity.
During the start-up phase, when the suction pipe is empty and the pump is wet with the fluid, the electric
pump unit is able to suck liquid from a maximum vertical distance of 2m.
It is important to note that it could take up to 1 minute for the pump to prime and that the presence of an
automatic dispensing nozzle on the delivery side will prevent the air trapped during the installation from be-
ing released and, therefore, the correct priming of the pump. For this reason, it is always advisable to prime the
pump without an automatic delivery nozzle, verifying the proper wetting of the pump.
Always install a foot valve to prevent the suction pipe from being emptied and to keep the pump wet at all
times. In this way, the pump will always start up immediately the next times it is used. When the system is in op-
eration, the pump can operate with back pressures of up to 0.5 bars on the suction inlet; beyond this point, the
pump may begin to cavitate resulting in a drop of the flow rate and an increase in the noise levels of the system.
In light of this, it is important to guarantee small back pressures on the suction side, by using short pipes with
diameters that are equal to or larger than those recommended, reducing bends to a minimum, and using
filters with a large cross-section and foot valves with minimum possible resistance on the suction side. It is very
important to keep the suction filters clean because, when they become clogged, they increase the resistance
of the system.
The vertical distance between the pump and the fluid must be kept as short as possible, and it must fall within
the 2m maximum required for priming. If the distance is greater, a foot valve must be installed to allow the
suction pipes to fill up and the diameter pipes must be larger. It is however recommended that pump not be
installed if the vertical distance is greater than 3m.
WARNING
If the suction tank is higher than the pump, an anti-siphon
valve should be installed to prevent accidental fuel leaks. Di-
mension the installation in order to control the back pressures
due to water hammering
It is a good system practice to install vacuum and air pressure
gauges right at the inlets and outlets of the pump, which allow
verication that operating conditions are within anticipated
limits. To prevent the suction pipes from being emptied when
the pump stops, a foot valve should be installed.
THE INSTALLER IS RECOMMENDED TO INSTALL A
SUCTION FILTER.

NOTICE
- Never start or stop the pump by connecting or cut-
ting out the power supply.
- Prolonged contact with some uids can damage the
skin. The use of goggles and gloves is recommended.
IF THE PUMP
DOES NOT PRIME
Depending on the system characteristics, the priming phase can
last from several seconds to a few minutes. If this phase is pro-
longed, stop the pump and verify:
- that the pump is not running completely dry (ll with uid from
the delivery line);
- that the suction pipe guarantees against air inltration;
- that the suction lter is not clogged;
- that the suction height is not higher than 2 mt.
- that all air has been released from the delivery pipe.
AT THE END OF
THE INITIAL
