9 4 Assembly
WARNING – Before starting any
work on the pump/motor, make sure
that the electricity supply has been
switched off and that it cannot be
accidentally switched on!
CAUTION – Before starting the
assembly, make sure that all parts
are delivered and have not been
damaged during transport
9 4 1 Preparation of the installation
To lower the pumps into the borehole, a crane or hoist is
required. You need also two clamps and ropes to lift the
components.
All parts have to be strong enough to withstand the weight
of the pump, the motor, the motor cable and the pipe
system.
It is also helpful to lower a pump dummy into the borehole
before you lower the pump to make sure that the hole
is completely free and the pump can slide into the hole
without collisions.
CAUTION – Pay attention to the label
on the motor if the liquid in the motor
need to be checked, filled up or if the
motor needs to get completely refilled

9 4 2 Installation
WARNING – Never stand under
suspended loads
CAUTION – Be careful not to bend the
pump, take particular care with pumps
with higher numbers of stages Make
sure that the pump never stands on the
motor cable, that the cable does not
get jammed or damaged by sharp
ledges or that the cable is not pulled
or jerked where it enters the motor
To connect the pump end and the motor you have to set
the motor with the clamps in the bore hole to fix it, cf.
figure below, "Figure 17: Motor in borehole".
Make sure that the clamps rest on a sufficient stable sup-
port structure, for example the well casing. If the structure
is not strong enough to carry the weight a support
structure has to be built that is suitable for the installation
process.
Figure 18: Preassembly of the pump
20
Screw the first piece of the pipe into the pump and install
a second clamp at the pipe, cf. figure below "Figure 19:
Installation depth of the first piece of pipe".
CAUTION – Make sure that the motor
cable is outside the clamps, otherwise
you will damage the cable
Note: Do connect the clamp directly
under the flange to leave some space
for mounting the bolts
If threaded joints are used instead of flanges they must
fit together to ensure that they do not work loose when
subjected to the torque reaction caused by the starting and
stopping of the pump.
The thread on the first section of the riser pipe which is to
be screwed into the pump should not be longer than the
threads in the pipe, cf. figure below "Figure 19: Installation
depth of the first piece of pipe".
