Typical Installation Positions

a) Vertical Installation
(deep well, pump sump, etc.)
CAUTION:
The construction of the well head must meet the relevant
regulations of the competent authorities! The unit must never
be installed with its suction strainer exactly at the level of the
well screen / filter!
Before installing the unit in narrow deep wells we recommend to
check narrow boreholes for dimensional accuracy over their
entire length, e.g. by inserting a pipe of the length and biggest
outside diameter of the pump unit. Sharp bends or bottlenecks
can make installation difficult or even impossible.
The unit is supported on the well head by supporting clamps
(low-weight units and low submergence) or a supporting flange.
The construction of the well head must meet the relevant
regulations of the competent authority.

Fig. 1 Vertical installation (in deep well, pump sump, etc.)
The suspension arrangement of the pump unit must be
designed and dimensioned so that all static and dynamic forces
can be absorbed and that the riser pipe cannot slip downwards.
The supporting clamps or flanges must be fastened at the well
head so that they cannot shift of lift off the well head.
The unit must never be installed with its suction strainer exactly
at the level of the well screen / filter! Excessive flow in the area
of the well screen / filter entails the risk of large amounts of
entrained sand clogging the well screen / filter and causing
excessive wear in the pump.
Pump units installed in a pump sump must generally be
equipped with a cooling or suction shroud (fig. 2).

CAUTION:

The instructions given in "a) Vertical installation" shall also apply
by analogy to horizontal installation, when the pump unit is fitted
on mounts (pedestals / supporting frame) supplied by us. If the
pump and motor are supplied ready mounted on a supporting
frame, on-site alignment of pump and motor will not be
e
necessary. If this is not the case, the relevant installation /
assembly drawing must be ordered, giving the following details:
-- installation height (floor clearance),
-- spacing of supports,
-- submergence X
T
The ground / foundation must be level and of sufficient
F
load-bearing capacity to accept the weight of the unit with
supports.

Air intake from an inlet arranged above the water level is not
permitted.
