How to adjust and replace the stuffing box gland

6.1.1 To adjust the stuffing box gland
If leaks occur on the stuffing box gland (material falling out) it must be adjusted. This is done using the nuts
on the thrust piece. Tighten all the nuts (up to a nominal size of Ø250 there are two, over a nominal size of
Ø300 there are five) evenly in sequence by half a turn at a time. The tightening torque should not exceed
approx. 20 Nm. The gland has been tightened correctly if the slide can be moved easily and no material is
drawn out with it.
6.1.2 To replace the stuffing box gland
If adjusting the gland does not produce the required result after it has been in use for some time, it should
be replaced. To do this, proceed as follows (see illustration in Section 8):
If necessary, remove the safety cover (S)
Undo the connection screws between the slide plate (5) and the spindle nut (7)
If necessary, remove the angle piece (switch lug) on the slide plate
Undo the M16 nuts on the rods (6)
Remove the drive
Undo the nuts on the thrust piece (4) and remove the thrust piece
Pull out the gland using a sharp object (marking scribe) and replace it with a new gland.
Please note: Offset the butt joints of the various gland cords
Assemble the unit again following the above instructions in reverse.
Replace the self-locking M16 nuts with new ones.
