4.3 Permanent, vertical, submerged
installation on auto coupling
Pumps for permanent, vertical installation in a pit can
be installed on a stationary auto-coupling unit and
operated completely or partially submerged in the
pumped liquid.
Make sure that the pipes are installed
without the use of undue force. No loads
from the weight of the pipes must be
carried by the pump. Use loose flanges to
ease the installation and to avoid pipe
tension at the flanges.
Do not use elastic elements or bellows to
connect the pipes.
In some installations, a plinth is required
beneath the auto coupling to ensure
correct installation of the pump. Consider
this during the design of the installation.
The guide rails must not have any axial
play as this may cause noise during
operation.
Proceed as follows:
1. Drill mounting holes for the guide-rail bracket on
the inside of the pit and fasten it provisionally with
two screws.
2. Place the auto-coupling base unit on the bottom
of the pit. If the bottom is uneven, the auto-
coupling base unit must be supported. Use a
plumb line to establish the correct positioning.
Fasten the auto coupling with expansion bolts.
3. Connect the outlet pipe in accordance with the
generally accepted procedures. Avoid 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 to the guide-
rail bracket at the top of the pit.
5. Unscrew the provisionally fastened guide-rail
bracket. Insert the expansion dowels into the
holes. Fasten the guide-rail bracket on the inside
of the pit. Tighten the bolts in the expansion
dowels.
6. Clean out debris before lowering the pump into
the pit.
7. Fit the guide shoe to the pump.
8. Slide the guide shoe along the guide-rails and
lower the pump into the pit by a chain secured to
the lifting bracket (fig. Lowering the pump along
the guide rails). When the pump reaches the auto-
coupling base unit, pull the lifting chain towards
the guide rail several times to shake off any
foreign substances (fig. Connecting the pump to
auto coupling). When the chain is unstrained, the
pump connects automatically to the auto-coupling
unit (fig.Submerged installation on auto coupling).
9. Hang up the end of the chain on a suitable hook
at the top of the pit. Make sure that the chain is
straight but not strained.
10. Adjust the length of the power 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 pit. Make sure
that the cables are not sharply bent or pinched.
11. Connect the power- and the control cables, if any.
The free end of the cable must not be
submerged as water may penetrate into
the motor.
