4.6.2 Installation example with filter pipe above
4.8 Other installations
Biral must be contacted for installation versions
in the pressure casing
with diaphragm container
with compressed-air vessel.
Warning
A flow casing must always be fitted
in installations in which the water intake
is above or at the same level as
the motor. This prevents solid matter
(sand and sludge) being drawn in directly
to overload the pump.
4.7 Installation in collection shaft
Warning
A flow casing with filter screen must be
fitted without fail in the case of
horizontal installation of the submersible
pump. The flow casing ensures
the necessary motor cooling.
The screen protects the submersible
pump from damage due to foreign
bodies and reduces the formation
of suction funnels. This permits pumping
out at lower levels. This provides
a greater effective volume.
