Installation, Operating and Maintenance Instruction
Maximum flows
The allowed operating range must comply with the
given of the order confirmation to secure trouble-free
operation. The maximum flow rates may not be
exceeded even temporarily. Otherwise damage may
be caused due to cavitation or reversal of the axial
thrust.
Installation position
Horizontal installation is not generally permissible.
With horizontal installation the reduced maximum
flows must be complied with, also the pump must in
be constructed without an installed non-return valve.
Protection against running dry
The pumps must not run dry under any circumstances
(not even for a short time for the purpose of checking

the direction of rotation), since overheating can
damage
recommend monitoring the required minimum water
level in order to protect the pump.
Pump Backflow
It is not permissible to drain the pressure line after the
pump has been switched off as the backflow speed
can be many times the operating speed and would
destroy the unit. A backflow through the pump can be
prevented by suitable non-reflux fittings as close to the
pump as possible insofar as a non-return valve are not
installed in the pump.
