Installation and Operating Instructions

18
The coupling ring required for installation of the AFLX/VUPX submersible pump must already be installed as
shown in
Figure 15a and 15b.
Before installation of the pump a suitable support (hook) for the chain, as well as
an opening and suspension (cable sock) for the cable must be provided in the sump or riser pipe.
Before or during the installation the motor connection cables should be fitted on site with suitable strain relief
(e.g. cable socks). Particular care should be taken that the cable insulation is not crushed or damaged by the
weight of the hanging cable especially in the area of the cable inlet.
ATTENTION
When raising the submersible pump out of the concrete sump or the steel discharge
pipe with the hoist ensure that the connection cables are lifted out simultaneously as
the pump itself is being raised.
Lowering of the AFLX and VUPX submersible pump into the coupling ring
ATTENTION
Before lowering the pump a direction of rotation check should be carried out.
•
Draw the cable hose over the end of the connection cable.

ATTENTION
The steel riser pipe, or concrete sump must be cleaned thoroughly (builder‘s rub-
ble, etc.). To optimise the inflow and to reduce the noise level it is important that one
pair of fins of the suction pipe are in line with the main flow direction of the inflow
chamber. This must be observed when fitting the pump into a sump or into a steel
discharge pipe.
•
Use lifting equipment to slowly lower the submersible mixed flow column/propeller pump into the shaft up to
the coupling ring; feed in the motor connecting cable at the same time. The submersible mixed flow column/
propeller pump centres itself automatically and leakage-free in the coupling ring.
•
Attach the lifting chain to the hook provided so that it cannot strike either the pump cable or the sump wall.
•
Tension the pump cable and fasten to the hook provided with the aid of the cable sock. Where a steel
pressure pipe is used the connection cable should be brought through the connection cable inlet and sealed
off in a watertight manner.
c
The connection cable should only be tightened sufficiently so that no tension acts at the cable inlet in
the head of the pump. The connection cable should not strike the chain or the sump wall.
•
If necessary, the steel riser pipe is sealed off in a watertight manner.
