Dry installation
There is a divided operating area when the machine is installed in this manner. The pumped liquid is
collected in the collector tank, and the machine is fitted in the machine room. The operating area
should be prepared according to the design or the manufacturer's planning guide. The machine is
assembled in the machine room at the place listed and connected with the discharge and pressure
side of the pipe system. The machine itself is not immersed in the pumped liquid.
The pressure and discharge side pipeline must be self-supporting, i.e. it may not be supported by
the machine. In addition, the machine must be connected to this without vibration or tension. Elas-
tic connectors (compensators) must be used. The machine does not need to be taken out of the
operating area for maintenance or repair work. It is possible, however, that the pipe system will
need to be dismantled.
The machine is not self-suctioning which means that the pump housing
must be filled completely with the pumped liquid. The min. liquid level in
the collector tank must be the same height as the top edge of the pump
housing.
With this installation type, the sliders on the intake and discharge side must be closed before the
machine can be disconnected from the piping system. The power supply cables must be laid out
safely, so that they are not damaged and do not present a danger to anyone.
Beware of burns
The housing parts can heat up to well above 40°C. There is a
danger of burns. After switching it off, let the machine cool down
to ambient temperature.
