Gland packing in Centrifugal Pumps
Gland packing in Centrifugal Pumps
(OP)
Is there any reason the gland packing is exposed to the Atmosphere? Can we use a completely sealed gland system with water flow and it would fulfill its purpose of cooling and lubricating the gland seal?

2) Whatever you "completely seal" the "gland system" with (another gland?) will also need to be lubricated, which means external leakage to atmosphere. Unless you seal the "gland system" with a mechanical seal, in that case you may be able to use the mechanical seal alone unless the shaft needs the support provided by packing.

It often caused confusion.
So I would really want a better description of the question before answering it, since I don't know what the question is actually asking.

Do you mean a packed gland with a lantern ring and water from the pump discharge is injected into it to lubricate the
packing and at the same time forming a higher pressuring liquid ring around the shaft.
This arrangement is commonly used for slurry application and where the stuffing box is expected to see -VE pressure.
