Drip leakage is essential to prevent
overheating of the gland area which will
cause seal failure.
The packing rings are located within the gland
housing and are tightened onto the shaft
sleeve by adjusting the gland follower. On
flushed packed glands a lantern ring replaces
the middle ring of packing. The shaft sleeve
is retained to the shaft by three socket set
screws and is sealed by an 'O' ring.
Removing the Packed Gland
1. Release and pull back the gland follower.
2. Remove the rotorcase with gland
housing, packing and gland follower still
assembled.
3. Loosen the shaft sleeve socket set
screws and extract the sleeve from the
shaft.
4. Inspect and replace the packing and
shaft sleeve if necessary.
Fitting the Packed Gland
1. Lubricate the 'O' ring, locate in shaft sleeve
and slide onto the shaft.
2. Tighten up the socket set screws, ensuring
tha the drilled dimples are aligned with
the grub screws. Permabond A130 or
equivalent should be used to secure grub
screws in their positions.
3. Fit gland spacer, gasket and gland housing
to the rotorcase.
4. Insert the packing rings and lantern ring (if
flushed packed gland). Make sure they
are in the correct order and positioned
with the scarf joints 120° apart.
5. Loosely locate the gland follower and
nuts.
6. Refit the rotorcase with packed assembly
over the shaft sleeves.
7. Adjust the packed gland see next page.
