1.
Clean sealing surfaces [DF], apply assembly paste and
place the sealing element [6] into roller [W].
2.
As a standard sealing element, the flat packing can
also be replaced by a different element, e.g. an O-ring.
Refer to the section "Specifications and Spare Parts"
for additional information.
3.
Screw flange [4] on rotor [90]. Make sure that dimen-
sion [MA] is maintained after mounting of rotor [90] to
roller [W]. MA ≥ 1 mm. Otherwise leakage will occur at
the sealing element and the rotary joint, the inner pipe
or roller [W] will be damaged. Mount stud bolts [9].
4.
Lift the rotary joint and insert it into the centering
element of the roller [W]. Design with inner pipe: the
inner pipe must be centered with the rotary joint and
the roller [W]. If it is hard to turn the inner pipe, make
sure it sits in the correct position. Wobbling and axial
tension will cause malfunctions of the rotary joint.
5.
If you use a flat packing, the rotary joint must be
aligned (refer to "Aligning the rotary joint when seal-
ing is done by means of flat packing").
6.
Observe the minimum distance [MA] - otherwise
leakage will occur at the sealing element and the rota-
ry joint and the inner pipe will be damaged:
MA ≥ 1 mm
7.
Mount nuts [10]. Maximum permissible tightening
torque as per section "Specifications and Spare Parts".
