Translation of the original instructions
• Vertical mounting with the motor located in the lower part is not allowed (see
fig. A11-A).
• The machines can be installed horizontally only using the appropriate kit
(optional). See fig. A11-B. Do not install in positions other than those described
or if an adequate support and ground fixing are missing.
• Check that there are no obstacles to the motor cooling air flow, ensure at least
100mm of free space above the fan (Fig. A5).
• Any liquid leaks or similar must be drained and must not flood the installation
site and/or submerge the unit.
• The electric pump must ALWAYS be securely fastened to a concrete foundation
or equivalent metal structure, of appropriate size and weight for the dimensions
and weight of the electric pump. Use screws suitable for the provided fixing
holes (see fig. A9 for dimensions and tightening torques).
• Place anti-vibration joints between the pump and the foundation to minimise
vibrations.
• Make sure the pump orientation is correct: the flow rate arrows on the pump
must be oriented facing the flow direction of the pipes.
• The connection pipes must be suitable for the pressure, temperature and nature
of the liquid pumped. Adequate sealing gaskets must be placed between the
pipe connections and the pump. The torques and forces that are exerted on the
flange connections must not exceed the values indicated in fig. A9.
• The motor can be rotated with respect to the factory position, according to the
installation needs. See fig. A12 and A13 in the appendix and the instructions in
Chap. 8, according to the model.
6.3 Two-pump high pressure units
The high pressure units must be installed as per fig. A8-B. The high pressure
pump must ALWAYS be positioned second, in the direction of the flow rate.
Incorrect connection of the high pressure pump may cause personal
injury and property damage.
6.4 Motor installation (Bare shaft pumps)
• Use only dynamically balanced motors with normal vibration rating (A)
according to IEC 60034-14, whose dimensions and power comply with IEC
standards 60072 and IEC 60034, IP55 protection rating and thermal insulation
class F or higher;
• Refer to fig. A9 to select the correct motor size (see rated power and IEC
interface)
• The characteristics of the original equipment motor are indicated in fig. A27.
Only use motors with equivalent characteristics, equipped with a constrained
pump side bearing and a preload spring on the opposite side. Alternatively, use
the thrust bearing unit kit accessories for pumps up to 4 kW.
The power indicated on the rating plate and in the tables refers to use
with clean water. For denser or more viscous liquids, consult the
Manufacturer.
6.4.1 Pumps without a thrust bearing unit up to 4 kW
PREPARATION OF THE MOTOR (fig. A17)
Remove the unified tab from the motor, if applicable.
Install the lowered tab into the motor shaft slot.
INSTALLING THE MOTOR (fig. A18)
Place the motor on the upper flange of the pump and insert the pin into the shaft.
Secure the motor to the pump using the screws. Tighten to the indicated
tightening torque.
Couple the two parts of the coupling.
Insert the assembly template between the coupling and the mechanical seal.
Fit the bolts and tighten them to the indicated tightening torque, making sure to
keep the two parts of the coupling symmetrical.
Remove the assembly template and keep it for future use.
Tighten the three grub screws of the rotating part of the mechanical seal.
Check: manually turn the shaft and pay attention to any metallic noises, indicating
potential coupling problems. If so, contact the Manufacturer.
Assemble the coupling cover guards.
6.4.2 Pumps with a thrust bearing unit up to 4 kW
INSTALLING THE THRUST BEARING UNIT AND MOTOR (fig. A19)
Place the flange with the thrust bearing onto the upper flange of the pump. Align
the holes of the two flanges.
Insert the pin into the shaft, lift the shaft and push the pin into the coupling hole.
Insert the removable part of the coupling and tighten the two screws, making sure
to keep the two parts of the coupling symmetrical.
Install the unified tab into the motor shaft slot.
Apply grease to the motor's shaft, around its entire circumference.
Place the motor on the flange, aligning the tab to the slot in the coupling. Secure
the motor to the pump using the screws. Tighten to the indicated tightening
torque.
Tighten the three grub screws of the rotating part of the mechanical seal.
Check: manually turn the shaft and pay attention to any metallic noises, indicating
potential coupling problems. If so, contact the Manufacturer.
Assemble the coupling cover guards.

VERTICAL MULTISTAGE ELECTRIC PUMPS
6.4.3 Pumps above 4 kW
INSTALLING THE MOTOR (fig. A20)
Check that the flexible coupling insert is inside the hole in the intermediate shaft
of the pump.
Install the unified tab into the motor shaft slot.
Apply grease to the new motor's shaft, around its entire circumference.
Place the motor on the upper flange of the pump. Secure the motor to the pump
using the screws. Tighten to the indicated tightening torque.
Assemble the coupling cover guards.
Put the guards back in at the end of the operations, if they have been
removed.
6.5 Additional protections and guards
• The surfaces of the electric pump may reach high temperatures depending on
the temperature of the pumped liquid. If deemed necessary, provide guards to
prevent accidental contact, without interfering with the normal functionality of
the machine (e.g. motor cooling).
• High-speed liquid splashes may be generated in the event of breakage,
installation errors or during filling operations. Provide appropriate fixed or
temporary guards, in the event that liquid spills can be dangerous or harmful
to human or animal health.
6.6 Accessories
• hydraulic connections kit: they enable connecting the hydraulic part to the
pipes (according to the type of connection desired).
• horizontal installation kit for vertical pumps: enables installation of the pumps
in a horizontal position, ensuring correct operation (fig. A11-B)
• assembly kit for two-pump high pressure units: enables the hydraulic
connection between the two pumps of the high pressure unit (fig. A8-B)
• optional thrust bearing unit kit for pumps up to 4 kW.
7 COMMISSIONING
Splashes of liquid dangerous to people or things may occur.
Do not start the pump without the coupling guards correctly installed.
During operation, the external surfaces of the pump and motor may
exceed 40°C (104°F). Do not touch the unit without adequate protections.
Do not place flammable material near the pump.
WARNING: The electric pump must NOT be started before filling. Its dry use may
irreparably damage the mechanical seal.
7.1 Priming
NOTE: It may be required to remove the coupling cover guards to perform this
operation.
Restore the guards immediately after the operation is completed.
Case with liquid level above the pump (B in fig. A5):
Close the delivery valve (8 in fig. A5).
• Loosen the pin on the filler cap (detail 1 in fig. A3).
• Open the suction shut-off valve (4 in fig. A5) to allow the liquid to enter, wait
until the water comes out of the side hole of the cap. Loosen the insert on the
drain plug (detail 3 or 4 in fig. A3) to facilitate filling.
• Tighten the filler cap pin and the drain plug insert.
Case with liquid level below the pump (A in fig. A5):
• Close the delivery valve (8 in fig. A5).
For versions 1/3/6/10:
• Remove the filler cap completely (2 in fig. A3. Loosen the insert on the drain
plug (detail 3 or 4 in fig. A3) to facilitate filling.
• Using a funnel, fill the pump until the water comes out, (it may be required to
repeat the operation several times).
• Tighten the filler and drain caps (tightening torques in fig. A3).
For versions 15/20/30/45/65/95:
• Remove both filler caps completely (2 and 5 fig. A3). Loosen the insert on the
drain plug (detail 3 or 4 in fig. A3) to facilitate filling.
• Using a funnel, fill the pump in one of the two holes until the water comes out
(it may be required to repeat the operation several times).
• Tighten the filler and drain caps (tightening torques in fig. A3)

7.2 Pump start-up

Before start-up check that:
• The electric pump is correctly connected to the power supply,
• The pump is correctly primed (see the previous paragraph),
• The delivery shut-off valve (8 in fig. A5) is closed and the suction valve (4 in
fig. A5) is open,
