When laying the connection pipes, you should make sure that the pump is not exposed to
any form of weight, vibration or tension. Moreover, the connection lines must not contain any
kinks or an adverse slope.
Please observe the illustrations, too, which are contained as an attachment at the end of the
present operating instructions. The numeric and other details included in brackets below
refer to these illustrations.
5.2. Installation of the pressure line
The pressure line conveys the liquids to be discharged from the pump to the point of
withdrawal. To avoid dynamic flow losses, one should use a pressure line having at least the
same diameter as the pressure port (1) of the pump.
The pressure line to be used for this type of application is an appropriate flexible hose - for
instance, a specially designed drainage hose.
To facilitate installation, a two-piece, multi-dimensional connection bow (10) is provided with
the following connectivity options: male 47,8 mm (1½ "), 41.91 mm (1¼"), and 33.25 mm (1
"), Hose connection of 40 mm and 32 mm. When adapting to the pressure line, the unneeded
narrower parts of the multi-dimensional connection piece are to be cut off at the
corresponding intended intersection points (a, b). For the removal of unneeded parts, it is
recommended to use a common household saw. When connecting to the 47.8 mm (1 ½ ")
external thread, only the bend without reducer is used. Carry out this adjustment if
necessary, before attaching the multi-dimensional connector to the pressure connection of
the pump.
5.3. Stationary installation
If the unit is used in a stationary installation, rigid pipes have proven to be the ideal choice for
the pressure lines. In this type of installation, we recommend that you incorporate a check
valve (non-return valve) in the pressure line immediately following the pump outlet so that no
liquid will flow back after the pump cuts out. To facilitate maintenance work, we also
recommend the installation of a stop cock valve downstream of the pump and check valve.
This arrangement is beneficial in that closing the stop cock will prevent the pressure line from
running dry after the disassembly of the pump. The dimension of the pump you can see in
Fig. 2.
