Permanent, horizontal installation in a pump room
The pump is bolted to the suction and discharge pipes by means
of flange connections. See fig. 8.

7.2 Submerged installation on auto coupling
Pumps for permanent, vertical installation in a tank can be
installed on a stationary auto coupling and operated completely
or partially submerged in the pumped liquid.
Proceed as follows:
1. Drill mounting holes for the guide rail bracket on the inGside of
the tank and fasten the guide rail bracket provisionally with
two screws.
2. Place the auto-coupling base unit on the bottom of the tank.
Use a plumb line to establish the correct positioning. Fasten
the auto coupling with expansion bolts. If the bottom of the
tank is uneven, the auto-coupling base unit must be supported
so that it is level when being fastened.
3. Assemble the discharge pipe in accordance with the generally
accepted procedures and without exposing the pipe to
distortion or tension.
4. Place the guide rails on the auto-coupling base unit and adjust
the length of the rails accurately to the guide rail bracket at the
top of the tank.
5. Unscrew the provisionally fastened guide rail bracket. Insert
the expansion dowels into the guide rails. Fasten the guide rail
bracket on the inside of the tank. Tighten the bolts in the
expansion dowels.
6. Clean out debris from the tank before lowering the pump into
the tank.
7. Fit the guide claw to the pump.
8. Slide the guide claw of the pump between the guide rails and
lower the pump into the tank by means of a chain secured to
the lifting bracket of the pump. When the pump reaches the
auto-coupling base unit, the pump will automatically connect
tightly.
9. Hang up the end of the chain on a suitable hook at the top of
the tank and in such a way that the chain cannot come into
contact with the pump housing.
10.Adjust the length of the motor cable by coiling it up on a relief
fitting to ensure that the cable is not damaged during
operation. Fasten the relief fitting to a suitable hook at the top
of the tank. Make sure that the cables are not sharply bent or
pinched.
11.Connect the motor cable and the control cable, if any.
7.3 Dry installation
Pumps in dry installation are installed permanently in a pump
room.
The pump motor is enclosed and watertight and will not be
damaged if the installation site is flooded with water.
Proceed as follows:
1. Mark and drill mounting holes in the concrete floor/concrete
foundation.
2. Fit the bracket or base stand to the pump.
3. Fasten the pump with expansion bolts.
4. Check that the pump is vertical/horizontal.
In order to facilitate service on the pump, we recommend using
isolating valves on either side of the pump.
5. Fit the suction and discharge pipes and isolating valves, if
used, and ensure that the pump is not stressed by the
pipework.
6. Adjust the length of the motor cable by coiling it up on a relief
fitting to ensure that the cable is not damaged during
operation. Fasten the relief fitting to a suitable hook. Make
sure that the cables are not sharply bent or pinched.
7. Connect the motor cable and the control cable, if any.

DN 300 4 x M24 3.0 kN
The strengths given above do not include safety
factor. The required safety factor depends on the
materials and method used for anchoring.
Make sure that the pipework is installed without
the use of undue force. No loads from the
pipework weight must be carried by the pump.
We recommend the use of loose flanges to ease
the installation and to avoid pipe tension at
flanges and bolts.
Do not use elastic elements or bellows in the
pipework; these elements should never be used
as a means to align the pipework.
In some installations, a plinth is required beneath
the auto coupling to ensure correct installation of
the pump. This should be considered during the
design of the installation.
The guide rails must not have any axial play as
this would cause noise during pump operation.
The free end of the cable must not be submerged
as water may penetrate through the cable into the
motor.
We recommend using a reducer between the
suction pipe and the pump in horizontal
installations. The reducer must be of the
eccentric type and must be installed so that the
straight edge is pointing upwards. In this way,
the accumulation of air in the suction pipe is
avoided and the risk of disturbance of operation
is eliminated. See fig. 9.
