Use of chains as lifting equipment prohibited
The following information must be observed
when attaching the lifting equipment:
• The lifting equipment must be fastened to the
transport shackle by a shackle. Carrying straps,
wire ropes and plastic ropes or chains may be
used as lifting equipment.
• The transport shackle must be dismantled after
positioning is complete.
• When attached to the housing parts, the lifting
equipment must be fastened in a loop. Chains
may not be used here!
5.3.2. Maintenance work
After a storage period of more than 6 months, the
following maintenance work must be carried out
before installation:
• Rotate impeller
• Check oil in the sealing chamber
Rotate impeller
1. Place the hydraulics horizontally on a firm surface.
Make sure that the hydraulics cannot fall over
and/or slip!
2. Carefully and slowly reach into the hydraulics
housing through the suction port and rotate the
impeller.
BEWARE of sharp edges!
Sharp edges can form on the impeller and the
opening on the suction port. There is a risk of
injury! Wear the necessary protective cloth-
ing, such as protective gloves.
5.3.3. Check oil in the sealing chamber ("Fig. 4: Screw
plugs")
The sealing chamber has a separate opening for
draining and filling the sealing chamber.
1. Place the hydraulics horizontally on a firm surface.
Make sure that the hydraulics cannot fall over
and/or slip!
2. Unscrew screw plug (D+).
3. Place a suitable tank under the screw plug (D-) to
collect the oil.
4. Unscrew screw plug (D-) and allow the oil to drain
out. If the oil is clear, does not contain any water
and the quantity matches the specification, it can
be reused. If the oil is contaminated, it must be
disposed of in accordance with the requirements
in the "Disposal" chapter.
5. Clean the screw plug (D-), renew the seal ring and
screw it back in.
6. Pour the oil in through the opening (D+) (quan-
tity: 1600 ml). Note the recommended operating
fluids.
7. Clean the screw plug (D+), renew the seal ring and
screw it back in.

5.3.4. Stationary dry well installation
In this installation type, the operating space is
divided: collector tank and machine room. The
fluid is collected in the collector tank and the
hydraulics is installed in the machine room. The
operating space must be blocked out as per the
manufacturer's configuration or consulting guide.
The hydraulics is connected to the suction- and
pressure-side pipe system at the specified point
in the machine room. The hydraulics is not im-
mersed in the fluid.
The suction- and pressure-side pipe system must
be self-supporting, i.e. it may not be supported
by the hydraulics. In addition, the hydraulics con-
nection to the pipe system must be free of stress
and vibrations. We therefore recommend using
elastic connection pieces (compensators).
The following operating parameters must be
complied with:
• The maximum fluid temperature is 70 °C.
• Motor cooling – To ensure sufficient motor
cooling by the motor fan, the minimum distance
to the rear wall must be complied with. See the
operating and maintenance manual for the motor.
• Max. ambient temperature – see the operating
and maintenance manual for the motor.
The hydraulics is not self-priming so that hy-
draulics housing must be completely filled with
the fluid. Ensure that there is an appropriate
inlet pressure. Air pockets are to be avoided at
all costs. Appropriate ventilation systems must
be provided.

Work steps
1. Installing the hydraulics: about 3–5 h
• Check that the pipe system is secured firmly.
• Fasten lifting equipment to the corresponding
attachment points and position the hydraulics
in the planned location.
• Fasten hydraulics to the foundation (6x attach-
ment points: 4x hydraulics, 2x support). We
recommend using anchor bolt for this fixation.
Note: The hydraulics is constructed in a "back
pull out" design. In other words, the motor,
bearing housing and impeller can be removed
as a unit without dismantling the hydraulics
housing from the piping. A minimum distance of
500 mm must be ensured here between the mo-
tor fan and the rear wall.
• Loosen the lifting gear and remove the trans-
port shackle from the pressure port.
Keep the transport shackle for later transport.
