All connection lines have to be perfectly tight since leaking lines may affect the
performance of the pump and cause considerable damage. Therefore, please
cause damage. 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 suction line
The intake of the suction line has to be equipped with a check valve (or
non-return valve) and an intake filter (Fig. 2).
Please use a suction line (2) having the same diameter as the
suction port (1) of the pump. If the suction height (HA) exceeds
4 m, however, it is recommendable to use a 25% larger diame-
ter - including appropriate reducer elements for the connectors.
The intake of the suction line has to be equipped with a check
valve (3) - or non-return valve - and an intake filter (4) (Fig.2).
The filter will keep away larger dirt particles contained in the
water which might clog or even damage the piping. The check
valve will prevent the pressure to escape after the pump has
cut out. Moreover, it simplifies the venting of the suction line by
enabling water to be filled in. The check valve with the intake fil-
ter - i.e. the entirety of the intake section of the suction port - must be immersed
by at least 0.3 m below the surface of the liquid to be pumped (HI). This will pre-
vent air from being taken in. In addition, please ensure a sufficient distance of the
suction line from both the ground and the sides of water courses, rivers, ponds
etc in order to prevent stones, plants etc from being sucked in.
use Teflon tape to seal the
contact surfaces between the

threaded sections of the lines
and the connection with the
pump (Fig.1). This use of seal-
ing material such as Teflon
tape is the only way to ensure
an airtight assembly.
