base to leak and the pump may be damaged. To prevent this, the use of guide pipes
is mandatory.
4.3. Position
Together, the coupling base, guide pipe bracket and guide pipes form the suspension
unit. This is installed in the operating area and connected to the discharge-side pipe
system.
The connected pipe system must be self-supporting. This means it must not be
supported by the coupling base.
Thecouplingangeismountedonthedischargeangeofthepump.Ithasguideclaws
to guide it along the guide pipe so that the pump can be connected to the coupling
base.
Thecouplingangeisautomaticallyconnectedtothecouplingbasebytheweightof
the pump.
Asealingringisinsertedinthecouplingangetoensurethatthereisnoleakagebe-
tweenthecouplingangeandthecouplingbase.Thesealingringispushedagainstthe
coupling base during operation, thus sealing the connection.
To ensure unimpaired operation, the suspension unit must be installed vertically
