FOREWORD
Denition of zones as shown in UNI EN 1127-1 standard
ZONE 0
Place where an explosive atmosphere made up of a mix of air and inam-
mable substances in the form of gas, vapour or mist is continuously pre-
sent, either for long periods or frequently.
Note: Generally speaking, said conditions, when they occur, involve the in-
side of tanks, pipes and containers, etc.
ZONE 1
Place where it is probable that an explosive atmosphere, made up of a mix
of air and inammable substances in the form of gas, vapour or mist, can
occur occasionally during normal operation.

M1 POSITIONING, CONFIGURATIONS AND ACCESSORIES
NOTE The pump must be secured in a stable manner.
ATTENTION 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
aect pump operation, always demand original acces-
sories.
M2 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 ow
considerably.
In these cases, to guarantee correct operation of the pump, it is necessary to reduce the re-
sistance 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
FOREWORD
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 uid,
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 being 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 operation, 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 ow 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 ben-
ds to a minimum, and using lters with a large cross-section and foot valves with minimum
possible resistance on the suction side. It is very important to keep the suction lters clean
because, when they become clogged, they increase the resistance of the system.
The vertical distance between the pump and the uid 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 ll 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.
ATTENTION
If the suction tank is higher than the pump, an
anti-siphon valve should be installed to prevent ac-
cidental diesel fuel leaks. Dimension 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.

N2 PIPING CONNECTIONS
FOREWORD - Before carrying out any connection, refer to the visual indications i.e.
arrow on the pump head, to identify suction and delivery.
ATTENTION Wrong connection can cause serious pump
damage.
PRELIMINARY
INSPECTION
- Before connection, make sure that the piping and the suction tank
are free of dirt and solid residue that could damage the pump and its
accessories. NEVER COLLECT THE FLUID FROM THE BOTTOM OF THE
TANK SINCE IT MAY CONTAIN IMPURITIES
- Before connecting the delivery pipe, partially ll the pump body, from
delivery side, with the liquid that needs to be pumped in order to faci-
litate priming.
- Do not use conical threaded ttings, which could damage the threa-
ded inlet or outlet openings of the pump if excessively tightened.
O INITIAL START-UP
FOREWORD
- Check that the quantity of uid 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.
- Make sure that the piping and line accessories are in good condition.
NOTE THIS PUMP IS NOT PROVIDED FOR FURTHER REGULATION
OF DELIVERY AND PRESSURE
ATTENTION Fluid leaks can damage objects and injure persons.
NOTE - Never start or stop the pump by connecting or cutting 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
prolonged, 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
START-UP
When priming has occurred, verify that the pump is operating
within the anticipated range, in particular:
- thatunder conditionsof maximumbackpressure,thepow-
er absorption of the motor stays within the values shown
on the identication plate;
- that the delivery back pressure does not exceed the maxi-
mum back pressure for the pump.
