ASSEMbLY AND INSTALLATION
5.1
Ambient conditions
Assembly is to be carried out in the following order. If the pump has to be
installed outdoors, then it is to be equipped with protection against sun-
light and weather influences. When positioning the pump, ensure that
sufficient room for access is provided for all types of maintenance work.

Correct installation of the pump
5.2.1 Suction side
The pump is to be positioned as near as possible to the liquid container,
so that the suction side is kept as short and straight as possible. The
suction line must be absolutely airtight and made of a suitable material,
so that it is not squeezed together under vacuum. The diameter must
correspond to the rated diameter of the pump hose. A larger diameter is
recommended in the event of viscose liquids. The pump is self-priming
and does not require an admission valve. The pump is reversible and
the suction connection can therefore comprise of one of two options.
Normally the option is selected which is best suited to the physical con-
ditions of the installation. It is recommended to use a flexible transition
between two fixed pipes and the hydraulic connection of the pump, in
order to avoid the transmission of vibrations.
