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.
