Warning!
Tipping (tilting) of the pump!
► The surface for setting up the pump should be clean, level and have
sufficient load-bearing capacity.
► Bolt the provided fastening points to the foundation for proper setup of
the pump according to the usual rules of mechanical engineering.
Warning!
Mechanical overload!
► Do not use the pump and its connection port as support of the piping.
(EN 809 5.2.1.2.3 and EN ISO 14847).
► Follow the general rules of mechanical engineering and plant
construction and the regulations of the manufacturers of connecting
elements (e.g. flanges). These regulations may include information on
tightening torques, max. permissible angular misalignment, tools/equipment
to use.
► Be sure to avoid any strain on the pump.
► After piping, check the alignment of the coupling (where applicable).
Caution!
Overload by foreign bodies!
► Before installing the pump in the system, remove all plastic films and
caps from the connectors.
Caution!
Dry running of the mechanical seal!
► The suction line must be hermetically sealed and laid such that no air
pockets can form.
► Avoid tight bends and valves directly in front of the pump. They impair
the incoming flow of the pump and the NPSH of the system.
► The suction head of the system must not be larger than the suction head
guaranteed by the pump.
► The piping nominal diameters of the system should be equal to or greater
than the DNE or DNA connections of the pump.
► For suction operation, install a foot valve.
► Route the suction line in ascending direction and the supply line at a
slight slope towards the pump.
► If the local conditions do not permit a continuous ascent of the suction
line: Provide a vent at its highest point.
► Install a shut-off valve in the supply line close to the pump.
► Open the suction side shut-off valve completely during operation.
► Do not use the suction side shut-off valve for controlling.
► Install a shut-off valve in the pressure line close to the pump. This can be
used to control the flow rate.
