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
