4. INSTALLATION, ASSEMBLY
4.1
SPECIAL ASSEMBLY TOOLS
To assemble the pump you do not need special tools, except for seal extractors (see
Maintenance).
4.2
INSTALLATION SITE INFORMATION
4.2.1
Space requirements for operation and installation
The space destined by the Customer to the installation of the machine should be enough to
gain access to, install and maintain the pump unit.
4.2.2
Inspection before starting installation
Before installation, the Customer must ensure that the environmental conditions of the se-
lected site comply with requirements specified under the contract.
In particular, unless expressly required and accepted in the order, the installation site should
not be exposed to the following environmental conditions:
- abnormal temperature;
- high humidity;
- corrosive atmosphere;
- explosion and/or fire hazard areas;
- dust, sandstorms;
- earthquakes and other similar external conditions;
- high level of vibrations;
- high altitude;
- flood hazard areas.
4.2.3
Foundation details
The metal baseplate shall be of sufficient size and strength to support induced stress.
When the pump unit is installed, it shall be firmly fixed in place by fastening bolts or by using
other securing methods.
Ground fastening bolts or other securing methods shall be of sufficient strength to prevent
the pump unit from moving accidentally.
4.2.4
Alignment requirements
The alignment operation must not submit the pump unit to axial and radial stress, therefore
the offset must always be lower than the tolerance limits expected for the coupling.
Great care shall be taken to align pump units equipped with magnetic drive coupling.
4.2.5
Suction lift
The suction lift, that is the vertical distance between the pump inlet mid-point and the free
surface of the tank to which the pump is attached, must not exceed 7 m (
this value can may
be lower depending on the rotation speed / viscosity reduction)
to allow pump priming and
avoid cavitation phenomena (Fig. II).
