4Installation
4.1 General precautions
Before starting, make sure that the safety instructions shown in Introduction and Safety on
page 5 have been fully read and understood.
WARNING:
All the hydraulic and electrical connections must be completed by a technician possessing the
technical
-professional requirements outlined in the current regulations.
WARNING:
Always wear personal protective equipment.
WARNING:
Always use suitable working tools.
4.2 Mechanical installation
4.2.1 Precautions
WARNING: Risk of injury due to improper floor installation
Install the unit on a
concrete or metal foundation base sufficiently strong to ensure permanent
and rigid support, suitable for the size and weight of the unit and as flat and even as possible.
4.2.2 Installation area
1. Follow the provisions in Operating environment on page 33.
2. Place the unit in a raised position in relation to the floor.
3. Check that the air clearance between the wall and the motor fan grid is:
•≥ 100 mm (4 in), to ensure suitable ventilation
•≥ 300 mm (12 in), to allow inspection and removal of the motor.
4. Make sure that any leaks will not cause flooding to the installation area or submerge the
unit.
Permitted positions
Only install the unit in the horizontal position.
4.2.3 Installation on concrete foundation
Foundation requirements
•The concrete must have a compression resistance of C12/15 and meet the requirements of
exposure class XC1 according to EN 206-1
•Sizes must be appropriate for the sizes of the unit support plate
•The foundation weight must be ≥ 1.5 times the unit weight (≥ 5 times the weight of the unit
if a quieter operation is required)
•The surface should be as flat and level as possible.

2. Levelling thickness
3. Tie rod
1. Drill the tie rod holes in accordance with the quantity, diameter and centre distances shown
in the technical catalogue.
2. Insert the tie rods into the holes and secure them with chemical anchors.
3. Remove the caps of the suction and discharge ports.
4. Place the unit on the foundation by inserting the tie rods into the holes in the plate.
5. Level the unit with a spirit level on the shaft and discharge port: the maximum permitted
tolerance is 0.2 mm/m (0.0024 in/ft).
6. Align the suction and discharge ports to their piping.
7. If necessary, insert levelling shims between the plate and the foundation: If the distance
between the tie rods is ≥ 800 mm (31 in), insert additional shims in the middle of the plate.
8. Tighten the nuts on the tie rods evenly and fully.

4.2.4 Frame installation
•The frame must be rigid and must not vibrate during operation
•The pump and motor feet support bases must be as level as possible
•Position the pump and the motor at a distance that allows the coupling to be fitted
•Ensure a gap of 4-6 mm (0.16-0.24 in) between the frame and the motor to allow for vertical
adjustment in case of replacement.
•Make sure that pump and motor are securely attached to the frame.
4.3 Hydraulic connection
4.3.1 Precautions
WARNING:
Piping must be sized to ensure safety at the maximum operating pressure.
WARNING: Danger of hot and/or toxic liquid escaping from non-sealed piping system
connections
Support the piping system independently to prevent them from weighing on the unit. Secure
the piping system to the unit ports making sure to comply with the permitted forces and
torques. Install appropriate gaskets between the unit and the piping system.
WARNING: Hot surface hazard
If the temperature exceeds 60°C (140°F), isolate the unit before touching it.
NOTE:
When carrying out welding activities never use the unit for grounding: risk of pitting damage
to the bearings.
4.3.2 Guidelines for the hydraulic system
1. Support the piping system independently to prevent them from weighing on the unit.
2. Remove any welding residues, deposits and impurities in the pipes that could damage the
unit; install a filter if necessary.
3. To reduce the transmission of vibrations between the unit and the system and vice versa,
install:
•anti-vibration joints on the suction and discharge sides of the unit
•dampers between the unit and the surface on which it is installed.
4. In order to reduce flow resistance, the pipe on the suction side must be:
•As short and as straight as possible
•For the section connected to the unit, straight and without bottlenecks, covering a
length equal to at least six times the diameter of the suction port
•Wider than the suction port; if necessary, install an eccentric reducer that is horizontal on
top
•Without bends; if this cannot be avoided, bends of a radius as wide as possible
•Without traps and 'goosenecks'
•With valves with a low specific flow resistance.
5. Install a check valve on the discharge side to prevent the liquid from flowing back into the
pump unit when this is at standstill.
6. Install a pressure gauge (or a vacuum pressure gauge, in case of suction lift installation) on
the suction side, and a pressure gauge on the discharge side, for checking the actual
operating pressure of the pump unit.

en – Original Instructions
18 e-IXP, e-IXPC, e-IXPF series – Additional Installation, Operation and Maintenance Instructions
7. To exclude the unit from the system for the purpose of maintenance, install:
•An on-off valve on the suction side
•An on-off valve on the discharge side, downstream the check valve and pressure gauge,
also useful for regulating the flow rate.
8. In case of suction lift installation, the suction pipe must have an increasing slope towards
the unit exceeding 2%; to avoid air pockets.
4.3.3 Auxiliary Connections
NOTE:
Unused or incorrectly used connections may cause malfunction and damage to the unit.
1. Suction port
2. Discharge port
3. Greasing unit M8 nipple
4. Greasing unit M8 nipple
5. G 1/2” drain
6. G 1/4" recirculation outlet (optional)
7. G 1/4” suction pressure port
8. G 1/4" discharge pressure port
9. G 1/2” drain
4.4 Alignment of the motor-pump coupling
NOTE:
Check the alignment of the motor
-pump coupling after the mechanical installation and
hydraulic connection of the unit.

Figure 2: Coupling with spacer
1. Ruler
2. Thickness gauge
See Figure 1 or Figure 2, depending on the type of coupling.
1. Place a ruler on the half-couplings.
2. Measure the distances at the points shown in the figure.
3. Turn the coupling by hand a little and repeat the measurement.
4. Repeat step 3 several times: the radial alignment is correct if the distances in relation to the
corresponding axes are the same at all points.
5. Check the distance between the half couplings with a feeler gauge.
6. Turn the coupling by hand a little and check the distance again.
7. Repeat step 6 several times: the axial alignment is correct if the distances are the same at all
points.

NOTE:
The radial and axial deviations
between the half couplings must not exceed the values
indicated by the manufacturer. Refer to the motor
-pump coupling instruction manuals for
more information.
The figure shows the correct alignment of the coupling.
