4. Mechanical installation
Fit the extra nameplate supplied with the pump at the
installation site.
Observe all safety regulations at the installation site.
Make sure there is adequate fresh air supply in the
pit.
DANGER
Electric shock
Death or serious personal injury
‐ Before starting any work on the
product, make sure that the power
supply is switched off and it cannot be
switched on unintentionally.
DANGER
Crushing hazard
Death or serious personal injury
‐ During installation, always support the
pump by lifting chains or place it in
horizontal position to secure stability.
CAUTION
Crushing hazard
Minor or moderate personal injury
‐ Do not put your hands or any tool into
the pump inlet or outlet after the pump
has been connected to the power
supply, unless the main switch has
been locked in position 0.
‐ Make sure that the power supply
cannot be switched on unintentionally.
The free end of the cable must not be
submerged as water may penetrate into
the motor.
Make sure that the pipes are installed
without the use of undue force. No loads
from the weight of the pipes must be
carried by the pump. Use loose flanges to
ease the installation and to avoid pipe
tension at the flanges.
4.1 Foundation
Foundations for pumps above 15 kW
The rotating equipment generates vibrations when an
impeller or rotor is turning at high speed. Proper
installation and anchorage of the pumps and
accessories are crucial to limit vibrations and achieve
reliable installation:
• The foundation and concrete must support the
weight of the pump including accessories, the
liquid passing through the pump and the forces
generated by the pump.
• The mass of the concrete foundation must be
minimum 3-5 times heavier than the weight of the
supported equipment and must have sufficient
rigidity to withstand the axial, transverse, and
torsional loads generated by the pump.
• The foundation must be 15 cm wider than the
baseplate for pumps up to 350 kW and 25 cm
wider for larger pumps.
• The concrete used in the foundation must have a
minimum tensile strength of 250 N/cm
2
.
• Always use epoxy grout to fasten the baseplate to
the foundation.
Pumps with DN 250 or DN 300 flanges
must be installed on a concrete
foundation.
