6.2.5 Gland packing

6.2.5.1 Pump fitted with a packed gland
A well run in and correctly adjusted packing gland
requires little maintenance. If, after some time, the
leakage becomes too great, the gland should be
tightened again in order to return these to a normal
level.

If re-tightening is not possible, new packing must be
installed

6.2.5.2 Gland packing inspection and removal
a) Remove the shield guards.
b) Slide back the gland.
c) Remove the packing rings with an extractor

designed for this purpose (including the lantern
ring if it exists; note its position and its direction
of rotation).

d) Inspect the state of the sleeve surface; the

presence of many marked grooves will indicate
that it must be replaced.

e) Carefully clean the different pieces of the

packing gland.

6.2.5.3 Gland packing fitting
If the packing is supplied as cord the packing must
be cut so that the external diameter is lightly
tightened and there is an initial gap between the
sleeve and the packing ring.

For that purpose, wind the packing helically around
the shaft sleeve or a chuck of the same diameter.
(Take precautions to avoid damaging sleeve).

Example of straight cut

Example of bevel cut

Ensure a tightening on the stuffing

box housing and not on the sleeve.
