3.3.4 Installing the column pipe
1. Fit a waterproof sealing between the mounting
flange and the concrete support structure. See
fig.
Fig. 14
Position of the waterproof sealing
2. Slowly lower the column pipe into the pit using
overhead lifting equipment.
3. Make sure that the column pipe is vertical and
rests securely on the concrete.
4. Tighten the anchor bolt nuts to ensure that the
column pipe cannot move.
3.3.5 Installing the KPL and KWM pump
Take particular care when installing the pumps, as
the procedure is not similar to that of other
submersible pumps. Make sure that the pump is
aligned with the anti-rotation brackets and in such a
way that pump rotation is prevented when the
impeller is running.
1. Make sure that the sealing O-ring is clean and
located in the groove on the bottom of the inlet
casing (KPL) or outlet casing (KWM). The O-ring
seals between the pump and the seat ring, thus
preventing backflow.
2. Slowly lower the pump into the column pipe using
the overhead lifting equipment. If necessary, in
lack of sufficient lifting height above the column
pipe, use an intermediate lifting ring.
3. Carefully guide the pump into position at the
bottom of the column pipe so that the pump does
not tilt in any way on the stop vanes at the bottom
of the column pipe.
4. Lift the pump 2 or 3 cm and turn it counter-
clockwise until the anti-rotation brackets touch
the nearest adjacent stop vanes.
3.3.6 Installing the cable suspension system in
the column pipe
It is important to fix the cables properly and
according to these instructions in order to avoid
damage to the cables during operation.
1. Clamp the wire rope and all cables together at
distances of 0.5 m between the clamps adapted
to the weight of the cables. See fig.
, cable
clamps, distance.
2. Fasten the wire rope to the eye at the top of the
column pipe.
3. Adjust the turnbuckle between the wire rope and
the eye of the beam. Make sure there is no slack
in the cable suspension, and that the cables are
fixed to the cable suspension and are unable to
swing during operation.
4. Lead the cables through the cable bushing of the
column pipe top cover.
5. Run the cables to the external terminal box.
Make sure that the cable bushing is fitted
correctly and prevents water from entering.
6. Fit the column pipe top cover on the upper part of
the column pipe using a waterproof gasket, and
tighten the bolts. Make sure that the cover
prevents water from entering.

Wrong direction of rotation will result in
pump damage.
- Check the direction of rotation before
the installation. See section
4.1.1 Checking the direction of rotation
to select the appropriate checking
method.
- The use of phase detection equipment,
such as the MP 204, protects the pump
from starting if the phase sequency is
changed.
Waterproof sealing
The pump is secured by its own weight
against the anti-rotation brackets. No
additional fixing is required.
Turbulence optimisation is not possible if
the pump is mounted in an oversize
column pipe.
If the pump system is configured for side
discharge, locate the cable inlet opposite
of the water outlet.
Cable damage could be caused by the
disruption in the direction of the water flow.
Do not position the cable inlet in the
column pipe near the water outlet to avoid
cable damage.
DANGER
Crushing of hands
Death or serious personal injury
- Do not put your hands or any tools 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/Off.
