5.2 Positional requirements

WARNING
Crushing of hands
Death or serious personal injury
‐
If the pump is to be installed in a position where it is
accessible, the coupling must be suitably isolated from
human touch. The pump can for instance be built into
a flow sleeve.
Depending on motor type, the pump can be installed either
vertically or horizontally. A complete list of motor types suitable for
horizontal installation is shown in section Motors suitable for
horizontal installation.
If the pump is installed horizontally, the outlet port must never fall
below the horizontal plane. See fig. Positional requirements.

with the pump and the installation, e.g. by installing a
guard.
During operation, the suction interconnector of the pump
must always be completely submerged in the liquid. Make
sure that the NPSH values are fulfilled.
