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
Vertical and horizontal installation is allowed. The
maximum operating flow must be kept. The pump
design is with or without integrated non-return valve
(at vertical or horizontal installation).
Protection against running dry
The pumps must not run dry under any circumstances
(not even for a short time for the purpose of checking

Check the pump/pump unit immediately upon
delivery/receipt of despatch for damage or missing
parts.

The pump/pump unit must be transported carefully
and by competent personnel. Avoid serious
impacts.

Keep the pump/pump unit in the same position in
which it was supplied from the factory. Take note
of the instructions on the packaging.

The intake and discharge side of the pump must
be closed with plugs during transport and storage.
Dispose of all packing materials in accordance
with local regulations.

Lifting aids (stacker, crane, crane mounting
device, lifting blocks, sling ropes, etc.) must have
the proper dimensions so that they can bear the

the direction of rotation), since overheating can
damage pump
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.
Other pipe connections are executed optionally on
customer request and are seen in the order
confirmation.
