Mounting with threaded rotor
B-14
1.
The rotor has either a right-hand or a left-hand thread
(R/L) on one end.
A sealing ring or an O-ring is used for sealing.
DN 06 … 50 with copper ring
DN 65 … 100 with O-ring (fig. B-14)
2.
Screw rotary joint into the roller.
Mounting with K flange [2] and inner ring [3]
NOTE
Mounting with K flange and screwed flange requires a minimum distance of [MA] ≥ 1 mm.
Otherwise leakage will occur at the sealing element, and the rotary joint, the inner pipe and
the roller will be damaged:
B-15
B-16
1.
Clean sealing surfaces [DF], apply assembly paste and
place the sealing element [7] into roller [W].
2.
The flat packing as standard sealing can also be
replaced by a different element, e.g. an O-ring. Refer
to the section "Specifications and Spare Parts" for ad-
ditional information.
3.
Insert bolts into K flange [2] and put the flange onto
rotor [80]. Place inner ring [3] into rotor groove.
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 [7], 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.
Insert and tighten screws [8]. Maximum permissible
tightening torque as per section "Specifications and
Spare Parts".
