7 - INSTALLATION INSTRUCTIONS
CAUTION!
Avoid installing the unit in narrow areas and lacking of ventilation where unfavourable conditions for the personnel
may take place. Allow the personnel a good visibility of the pump assembly by providing a proper lighting.
A proper pump installation must not transmit vibrations to ambient in the permanent presence of personnel.
Information to determine the piping sizes and floor space requirements can be obtained from dimension drawings and
other engineering data. The information required is:
- size and location of suction and discharge flanges
- size and location of all connections for flushing, cooling, heating, draining, etc.
- location and size for mounting bolts for monoblock pump and/or baseplate and/or frame.
In the event additional accessories are required to complete the installation such as separators, piping, valves, etc. refer
to following chapters 7.1 - 7.2 - 7.3.
Proper lifting devices should be available for installation and repair operations.
Pump assembly should be installed in an accessible location with adequate clear and clean space all around for
maintenance, so that an efficient and proper installation can be made.
It is important to have proper room around the unit for ventilation of motor. Avoid installing the unit in hidden locations,
dusty and lacking of ventilation.
Pump/motor assembly should not be installed in narrow areas, dusty, toxic and explosive ambient. In the event this is not
possible it is recommended to ventilate the areas to help cooling the motor (minimum 0,6 metres of empty room around).
All components used in the installation should comply with the safety codes. The installation must not transmit vibrations
to the pump.
Select a mounting pad that will minimise vibrations or torsion of the pump baseplate or frame. It is generally preferred to
have a concrete base or sturdy steel beams.
It is important to provide adequate anchor bolting for the pump frame or baseplate to be firmly attached to the foundations
(see fig. 4).

Concrete pads and other concrete works must be aged, dry and clean before the pump assembly can be positioned in
place. Complete all the work relating to the foundations and grouting of the pump assembly, before proceeding with the
mechanical and electrical portion of the installation.
7.1 - INSTALLATION OF PUMP/MOTOR ASSEMBLY
Place the pump assembly on the foundation pad aligning the anchoring bolts.
If necessary use metal spacers to level the unit and check the flange connection for good horizontal and vertical planes.
Tighten the foundation bolts.
Check again the level of the assembly and proceed with the pump/motor alignment verification as discussed in paragraph
8.2.
In cases where the pump is installed on a baseplate separated from that of the motor (due to expected piping forces,
moments or as it often is in cases of large units) it is recommended to first install the pump and then proceed with the
motor installation and alignment.
7.2 - SUCTION AND DISCHARGE PIPING
Identify first locations and dimensions of all connections required to interconnect the pump with the installation, then
proceed with the actual piping: connect the pump suction (see fig. 5) and discharge flanges, the service liquid line and all
other service connections.
CAUTION!
Possible contact with hazardous media and hazardous substances, cold or warm. Pay maximum attention to
the proper connection of the system pipelines to the respective pump’s connections.
Operate only provided with apposite protective devices.
To prevent the introduction of any limb in the pump during installation, do not remove protection cap from flanges
or cover from openings until the piping is ready for hook-up.
