• Ensure that lifting equipment can be fitted with-
out any trouble, since this is required for assembly
and removal of the pump. It must be possible to
reach the pump safely in its operating and storage
locations using the lifting equipment. The ma-
chine must be positioned on a firm bearing
surface. For transporting the pump, the load-car-
rying equipment must be secured to the lifting
eyelets provided. When using chains, they must
be connected with a shackle to the lifting eyelets
or the carrying handle. Lifting equipment must be
technically approved.
• Electric power cables must be laid out in such
a way that safe operation and trouble-free
assembly/dismantling are possible at all times.
The pump must never be carried or dragged by
the power supply cable. Check whether the cable
present is long enough for its cross-section and
its installation type.
• When using switching devices, the corresponding
protection class must be observed. In general,
switching devices are to be installed outside
potentially explosive areas in such a way that they
are protected from flooding.
• When used in an explosive atmosphere, it must
be ensured that the pump and all accessories are
approved for this purpose.
• Structural components and foundations must
be of sufficient stability in order to allow the
product to be anchored securely and functionally.
The operator or the supplier is responsible for the
provision of the foundations and their suitability
in terms of dimensions, stability and strength.
• If the motor housing is to be taken out of the
fluid during operation, the operating mode for
non-immersed operation should be followed.
To keep dry motors sufficiently cooled when
they are not immersed, they must be flooded
completely before being switched back on!
• Never let the pump run dry. The water level must
never fall below the minimum. Therefore, we
recommend installing a level control system or
a dry-running protection system where there are
great variations in the level.
• Use guide and deflector plates for the fluid intake.
If the water jet reaches the surface of the water,
air will be introduced into the fluid, which can
accumulate in the pipe system. This can result in
inadmissible operating conditions and to deacti-
vation of the entire system.
• Check that the available planning documentation
(installation plans, layout of the operating area,
intake ratios) is complete and correct.
• Please observe all regulations, rules and legal
requirements for working with and underneath
heavy suspended loads. Wear appropriate protec-
tive clothing/equipment.
• Please also observe the applicable national acci-
dent prevention regulations and trade association
safety provisions.

5.3.1. Unloading horizontally delivered pumps
To prevent the material from being affected by
excessive tensile and flexural forces, the pumps
are delivered horizontally on special transport
frames.

1 Bearing surface
2 Hydraulics
3 Attachment point on the motor
For unloading and transporting these pumps, the
following must be adhered to:
1. Preparatory measures
• Place the pump, including the transport frame,
on a firm, level bearing surface.
• Secure the 1st suspension cable to the hydrau-
lics and the 1st lifting device.
• Secure a 2nd suspension cable to the attach-
ment points on the motor and the 2nd lifting
device.
Only use suspension cables as the lashing de-
vices. Chains can damage parts of the housing
and do not prevent slipping!
2. Raising the pump
• Raise the pump slowly with both lifting devices.
• Ensure that the pump remains horizontal.
• Remove the transport frame.
3. Aligning the pump vertically
• Using both lifting devices, slowly bring the
pump into the vertical position.
• Ensure that parts of the housing do not touch
the ground. Because the contact surface is
small, very high point loads are created which
can damage the housing.
4. Setting down the pump
• When the pump is vertical, lower it slowly onto
the ground.
• The pump can now be prepared for the particu-
lar installation type.
Keep the transport frame in good condition for
later use.
5.3.2. Stationary wet well installation
A suspension unit must be installed for wet well
installation. This must be ordered separately.
The pipe system on the pressure side is connect-
ed to this.
The connected pipe system must be self-sup-
porting, i.e. it may not be supported by the
suspension unit.
The operating area must be laid out so that the
suspension unit can be installed and operated
without difficulty.
If the motor is to be replaced during operation, it
is imperative the following temperature values are
observed:
• The max. ambient temperature
• The max. fluid temperature
