7 Installation and electrical connection
(Motor / pump coupling system)
DANGER! Risk of getting crushed!
The installation or removal of the product must
not be performed by one person alone.
Measures should be taken to bar persons from
standing beneath a suspended load. Further-
more, it is also prohibited to move suspended
loads over exposed workplaces where people
are present. The fastening devices should be
adapted to the conditions at hand (weather,
hooking system, load, etc.) Use suitable fas-
tening devices to handle the weight of the pro-
duct.
WARNING! Danger of personal injury!
The installation and electrical connection should
be performed only by qualified personnel in
compliance with local regulations. This section
provides instructions on the recommended
methods of installing pumping sets on to con-
crete foundations. Careful attention must be
paid to the customer and contractor's installa-
tion drawings during the installation procedures
to ensure that the pumping set is accurately
positioned on the correct datum levels.

Example:
• Duty point: 100 m3/h – 35 m – pump efficiency
78 %
• Pump shaft power : 12,5 kW
• Electrical motor rating (including margin) :
12,5 * 1,15 = 14,3 kW
• IEC motor power rating available : 15 kW
Use a foot mounted motor B3 (IM 1001) which
comply to the IEC34-1 standard.
7.1.2 Coupling selection
Use a semi-flexible coupling to link the pump to
the driver.
Select the size of the coupling in accordance with
the recommendation of the coupling manufactu-
rer. Strictly follow the coupling manufacturer's
instructions for the fitting of the coupling bet-
ween the pump and the motor. (The coupling
must comply with the standard EN349). The alig-
nment of the pumps and the motor must be che-
cked after the installation of the pump set on its
foundation and when the piping is connected. In
addition an alignment control must take place
when the system works at its nominal tempera-
ture. The coupling guard must comply with the EN
953 standard in order to avoid any contact with
rotating parts during operations.

WARNING! Danger of electric shock!
Any hazards from electrical current should be
ruled out.
Any instructions from local or general directives
[e.g. IEC, VDE etc.] or directives of the local elec-
tricity supply companies must be observed.

7.1 Installation of bare shaft pump

It is strongly recommended to use component
such as coupling, guards, motors, base plates sup-
plied by Wilo to install a bare shaft pump on a base
plate.
It is mandatory that those components should be
CE certified and the coupling guard must comply
with the regulation EN 953.
7.1.1 Electrical motor selection
Select an electrical motor with sufficient power
margin regarding the motor rating. The table bel-
low will guide you in this selection.

7.1.3 Selection of a base plate
Select a base plate in accordance with the local
regulations, sufficiently large and strong to sup-
port the pump and motor.
7.1.4 Pumpset assembling
Fix the pump and motor equipped with their half
coupling on the base plate and make the align-
ment of those elements. It is recommended to fit
the coupling guard supplied as accessories by
Wilo.
