9.2 General technical data

The following data refer to standard values. For deviating data,
please consult the manufacturer.
9.2.1 Dry running protection
The aggregate is not protected against dry running. Dry running
protection has to be provided at the installation site.
9.2.2 Service life
The service life of the aggregate is approx. 20,000 h.

Any data referring to the service life of the aggregate are
subject to conditions of use in accordance with the manu-
facturer's specifications.
9.2.3 System pressure
The max. permissible static system pressure of the aggregate is
2.5 bar.

9.2.8 Sealing
The aggregate is hermetically sealed by the separating can. The
separating can and the volute casing are sealed by means of an
O-ring. Another O-ring is used to seal the gap between the
motor and the separating can.
9.2.9 Ambient conditions

The aggregate should be installed at a dry place either
indoors or outdoors under a roof. The ambient air must be
free of vapours containing acid or solvents.

Do not use in Ex zones.

Operation under other ambient conditions has to be agreed
with the manufacturer.
