•
Drill mounting holes for the pipe bracket on the inside
edge of the shaft opening. If this is not possible due
to the space available, the pipe bracket can also be
mounted in an offset position with a 90° folded plate
on the underside of the shaft cover. Provisionally fas-
ten the pipe bracket with 2 screws.
•
Align the coupling base to the shaft floor, use a
plumb bob from the pipe bracket - the guide tubes
must be exactly perpendicular! Fasten the coupling
base to the shaft floor with heavy-duty dowels. En-
sure that the coupling base is exactly horizontal!
If the shaft floor is uneven, support the bearing sur-
face accordingly.
•
Mount the pressure pipes with fittings free of tension
according to the usual mounting principles.
•
Insert both guide tubes into the eyelets on the cou-
pling base and cut to size according to the position
of the pipe bracket. Unscrew the pipe bracket, insert
the tabs into the guide tubes and fasten the bracket
completely. The guide tubes must be positioned with
no play at all, otherwise loud noises will occur during
operation of the pump.
•
Clean the shaft of any solid material (debris, stones,
etc.) before commissioning.
•
Mount the coupling counterflange of the automatic
coupling system on the pump pressure ports (thread
or flange connection). Ensure that the rubber seal is
firmly seated in position in the counterflange (as a
seal against the coupling base), so that it will not fall
out when lowering the pump.
•
Attach the chain to the pump handle or lifting
lugs. Insert the pump with the guide claws of
the coupling counterflange between the guide
tubes in the shaft. Lower the pump into the shaft.
If the pump is seated on the coupling base, it
automatically seals itself off to the pressure line and
is ready for operation.
•
Hang the end of the discharge chain from a hook at
the shaft opening.
•
Hang the motor connection cable of the pump in the
shaft at an appropriate length, with strain relief. Make
sure that the cables can not be bent or damaged.
Dry Installation
For the installation of the pump outside of the collecting
duct, a feed line to the pump housing inlet must be con-
nected. For dry installation, only the models with a motor
cooling jacket are suitable.
The installation of the pump can be either vertical or
horizontal.
•
Attach the pump stand or support feet to the pump.
•
Mark the position of the pump on the ground, drill
and anchor pump with heavy-duty dowels.
•
Use the fittings to mount the suction and pressure
pipes free of tension according to the usual mount-
ing principles
5.3. Use of chains
Chains are used to lower a pump in the operating space
or to pull it out. They are not intended to secure a floating
pump. Intended use is as follows:
•
Attach one end of the chain to the eyelet or the han-
dle of the pump
•
Attach the other end to the lifting device.
•
Ensure tension on the chain, and then lift the pump in
a slow and controlled manner.
•
Swing the pump then over the operating space and
lower it gently. When using a suspension unit, ob-
serve chapter. 5. Commissioning.
•
Lower the pump to the operating point from and
make sure that the pump has a secure footing or the
coupling system is engaged correctly.
•
Remove the chain from the lifting device and secure
it to the safety chain, which is located at the top
of the operating room. This ensures that the chain
can not fall into the operating area and constitutes a
danger to anyone.
Please note the following diagrams during installation.

5.4. Initial operation
This chapter contains all the important instructions for op-
erating personnel for the safe commissioning and opera-
tion of the machine. The following information must be
strictly adhered to and checked:
•
Type of installation
•
Operating mode
•
Minimum/max water coverage. Immersion depth
After a long downtime, these specifications are also
to be checked and any defects are to be rectified! The
operation and maintenance manual must always be
kept with the machine, or be kept in a designated place
where it is always accessible for all of the operating
personnel.
