WARNING
Fluid: PETROL,
Temperature: 20° C
Suction conditions: The pipe and the pump position
relative to the fluid level is such that a low pressure of
0.3 bar is generated at the nominal flow rate.
Under different suction conditions higher low pressure
values can be created that reduce the flow 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 filter clean
• use a pipe with a diameter equal to, or greater than,
indicated (see Installation).

L2 NOTES ON SUCTION AND
DELIVERY LINES IF THE PUMP
DOES NOT PRIME
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 flow rate capacity). AT THE END OF
SUCTION THE INITIAL
START-UP
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
O
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- USE
CURRENT eration, the pump can operate with back pressures of up to 0.5 bars on the suction inlet; beyond this point, the PROCEDURE
Max (*) (A) 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
25
diameters that are equal to or larger than those recommended, reducing bends to a minimum, and using
26
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.
If the suction tank is higher than the pump, an anti-siphon
WARNING
valve should be installed to prevent accidental fuel leaks. Di-
mension the installation in order to control the back pressures

WARNING
It is a good system practice to install vacuum and air pressure
gauges right at the inlets and outlets of the pump, which allow
verification 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.

Before carrying out any maintenance work, DISCONNECT THE PUMP from
any electrical and hydraulic power source.
During maintenance, the use of personal protective equipment (PPE) is com-
pulsory.
In any case always bear in mind the following basic recommendations for a
good functioning of the pump
