Transport, storage, assembly and Installation
The pump is to be positioned as near as possible to the liquid con‐
tainer, so that the suction side is kept as short and straight as pos‐
sible.
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 conditions 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.
The discharge line is to be kept as straight and short as possible,
in order to avoid performance reduction.
The diameter must correspond to the rated diameter of the pump
hose. Bei viskosen Flüssigkeiten wird ein größerer Durchmesser
empfohlen.
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.
The peristaltic pump is equipped with spacer plates (7), which are
used to adjust the precise pressure distance of the shoes (5)
(depending on the speed and operating pressure).
