APPENDIX A
GLAND SEALING WATER FLOWRATE
Alternative Stuffing Box gland packing configurations may be used depending on the particular pump application,
as shown in Fig 4, with each one having different gland sealing water flow rates.
Fig 4(a) shows the Full Flow Water Seal arrangement, with a metal Lantern Restrictor, being suitable for positive
intake head and small suction lifts. This seal arrangement has maximum gland sealing water consumption.
The Low Flow Water Seal arrangement shown in Fig 4(b) has a close-fitting Lantern Restrictor, and is suitable
for high suction lift applications. Gland sealing water flow rates for this sealing option are about thirty percent of
that shown in Fig 4(a).
The Ultra Low Flow Water Seal arrangement shown in Fig 4(c) has a ring of packing between the Lantern Ring
and the pump casing interior to limit gland sealing water flow rate to a very small value, typically about one
percent of that shown in Fig 4(a). This type of sealing arrangement is used where only very small quantities of
gland water addition to the pumped fluid can be tolerated, eg in alumina process pumping applications.
Recommended values of gland sealing water flow rates to be provided are shown in Table C.
These flow rates include a provision for wear, which progressively reduces the velocity of sealing water issuing
from Stuffing Box chamber into the pump casing, and the corresponding effectiveness of excluding solid particles
from the packed gland.
