These operating instructions contain relevant information
and precautionary notes. Please read the manual
carefully before assembling, electrical connection and
commissioning.
General Observations
This pump has been developed according to the
most advanced and recent technology, as well as in
compliance with the regulations in force. Moreover, the
pump is subject to a permanent quality control.
These operating instructions are intended to help you
better understand the pump operation and to show you
its possible applications.
The manual contains important information necessary
for reliable and profitable operation. Compliance with the
operating instructions is of vital importance to ensure the
reliability and a long service life of the pump, as well as to
avoid any accident risk due to improper use.
This pump must not be operated beyond the limit values
quoted in the technical specification. Any indication
concerning the nature, the density, the temperature, and
the rate flow of the pumped liquid, as well as the rotation
speed, the pressure and the power of the motor shall be
observed. Any other instruction contained in this manual
or in the documentation enclosed to the agreement shall
be observed as well.
The rating plate bears the type series, the main
operation data, and the serial number. Please, quote this
information in all request of intervention or assistance,
and when ordering spare parts.
Safety regulations
This manual contains essential instructions that must be
observed during installation, operation and maintenance.
Therefore, this operating handbook must be read and
understood both by the person in charge of assembling
the machine and by all qualified personnel appointed by
the responsible for installation to perform its operation.
These operating instructions must always be available on
use site of the machine.
Marking of coded instructions within the manual
The safety instructions contained in this manual, whose
inobservance might cause hazards to person, are marked
with the general hazard sign, i.e.:
m
(hazard sign)
Risks due to inobservance of safety instructions
Inobservance of safety instructions may cause physical
and material damages, as well as environmental pollution.
Non-compliance with safety instructions will also lead to
the complete loss of any warranty right.
In particular, the inobservance of the above mentioned
instructions may for example result in:
• failure of main machine/unit functions;
• failure of maintenance procedures;
• hazard of electrical, mechanical or chemical nature.
Safety regulations
All safety instructions contained in this manual shall be
observed, as well as any other national regulation on
accident prevention, and any internal regulation on the
use of machineries and on occupational safety.
Safety instructions for control, maintenance, and
operation works
The person in charge must verify that all maintenance,
inspection and installation works are performed by
qualified and authorised personnel. Before performing
these works, the personnel must be aware of the content
of this manual.
All interventions on the machines must be carried out
only during total standstill of the mentioned machines.
Strictly observe the shutdown procedure described in this
manual.
Pumps conveying fluids hazardous to health must be
decontaminated.
Immediately after completion of work, all safety and
protective devices must be re-installed and/or re-enabled.
Modification and manufacture of Spare parts
Any reconstruction or alteration of the machine must
be performed by the manufacturer before being carried
out. Original spare parts and accessories supplied by
the manufacturer ensure safety. The manufacturer is not
in any case liable for damages due to the use of non-
original spare parts!
1 . DELIVERY AND STORAGE
1 .1 Delivery
These submersible pumps are supplied in their own
original packing in which they should remain until
installation.
Avoid the pump to be bent when it is not packed, since
this may cause the misalignment and the damage of the
pump itself.
The loose data plate supplied with the pump should be
fixed close to the electric control equipment.
The pump shall not be exposed to unnecessary impacts
and crashes.
1 .2 Storage and Handling
Storage Temperature:
Pump: from -20°C to +60°C
The pump should not be exposed to direct sunlight.
If the pump has not been packed, it shall be stored
horizontally, adequately supported, or vertically, to
prevent the misalignment of the pump. During storage,
the pump can be supported as shown in Fig. 1.

If the pump is not used in vertical position, both the pump
side and the motor side must be supported. Note that the
centre of gravity will vary according to the pump type.
2 . GENERAL DATA
2 .1 General description
The submersible pumps are multistage pumps working
with counterclockwise rotation direction (observing from
the delivery side) directly coupled to special submersible
motors (according to NEMA standards).
Pump identification code
2 .2 Applications
These submersible pumps are designed for a wide range
of applications, such as the supply of water to private
homes, water systems and industries.
These pumps are necessary in case of lowering of the
groundwater level, as well as for pressure increase.
Submerge the pump completely under the water level
both if it is installed horizontally and vertically. See
paragraph
3.1 Positioning Limits
.
2 .3 Pumped liquids
Pumped liquids must be clean, compatible with pump
components and materials, without solid particles or
fibres.
The maximum sand content in the water must not exceed
50 g/m³. A greater sand content in the water reduces the
service life of the pump and increases the risk of blocking.
When pumping liquids with a density higher than that of
water, motors with correspondingly higher outputs must
be used.
3 . INSTALLATION / PREPARATION
3 .1 Positioning limits
m
If the pump has to be installed in a position
where it is accessible to people, any possibility
of contact with the coupling must be avoided.
The pump might for instance be equipped with a
protective shield.
The pump is suitable for both vertical and horizontal
installation, however, the pump should
never
be installed
inclined downwards, see Fig. 2.
Note:
During operation, the suction support must always
be completely submerged.
In special conditions, it may be necessary to submerge
the pump even deeper, depending on the operation
conditions of the pump, as well as on temperature and
NPSH values.

3 .2 Diameter of Pump/Motor
Check in the technical catalog the maximum diameter of
the pump and the pump with motor.
Verify the borehole with an inside calliper to ensure
unobstructed passage.
3 .3 Check valve on the delivering piping
The pump is equipped with an embedded check valve
in the delivery opening. However, it is recommended,
especially if the pump directly feeds a distribution network
subject to pressure, to install another check valve on
the delivery piping at no more than 10 meters from the
minimum well level. (If this latter is not known, use the
delivery opening as minimum level).
Its presence reduces hydraulic shocks due to starts and
stops.
4 . ELECTRICAL CONNECTIONS
m
Before starting to work on the pump, make sure
that the power supply has been disabled and
that it cannot be accidentally switched on.
4 .1 General remarks
The electrical connections should be carried out by an
authorised electrician according to the regulations in
