3.21.3.7 Shaft seals
A. Gland packing PO
• For pumps with gland packing, regularly check the packing for leaks. A slight leakage is normal.
• Regularly check connections on the lantern ring (if applicable).
• If the gland packing leaks excessively or when the pump needs serve, the old packing rings must
be replaced. This can be done without disassembling bearing and bearing bracket.
1. Gland packing disassembly
1. Loosen the gland nuts (2070).
2. Push back the gland (2040) as far as possible.
3. Remove the old packing (3000) rings using a packing extractor.
4. Thoroughly clean intermediate casing and shaft.
2. Gland packing assembly
1. First bend and twist the packing ring as
shown in the figure.
2. Wrap it around the pump shaft and
press the ring firmly against the bottom.
• Use packing seals with the right dimensions
• Do not use a sharp object to push the ring
into place as this may cut the ring
(e.g. a screwdriver).
Use a halved section of piping of
the correct size instead.
3. Place the following rings in the same way.
Push them down one by one. Take care that
the cuts in subsequent rings are rotated at
90 intervals.
4. After all packing rings have been mounted,
push the gland (2040) against the last mounted
packing ring and tighten the nuts cross-wise by hand.
Do not overtighten the nuts!
To avoid running dry, shaft gland packing must always leak a little.
3. Running-in of the pump
1. Fill the pump and start it up.
2. Allow the new packing rings to run in for a few hours.
Note!
During this time the gland packing will leak more than usual!
3. While running-in the pump check that it is not overheating. Pay attention to the rotating
shaft!
4. After the running-in period slightly tighten the gland nuts cross-wise, until the gland
packing does not leak more than a few drops per minute.
