Shaft Seals
The shaft seals on your mixer may be one of the several styles listed below, packing gland or a
purchased seal from another supplier. Information on purchased seals will be located at the end
of this manual with the purchased parts manuals.
Packing Gland Seals
1. Machines equipped with Packing Gland seals will need the packing push ring adjusted if any
leaking is sighted during operation. The seals have not had their final setting at the factory
because the machine needs to be affixed and running for the proper setting. If dust is leaking
from the shaft areas of the machine, the seals must be tightened.
2. Tighten seals slowly until product leaking subsides. CAUTION: Do not over-tighten the seals,
as this will cause undue wear and excessive friction on the main shaft. If excessive heat is
noticed on the shaft or bearing, loosen the push ring and call Scott Equipment for further
discussion.
3. Air purge seals are sometimes supplied with the equipment. These seals require 3-5 PSI of
clean, dry, filtered air.
Below is a typical arrangement of a Scott 3-ring air purge seal. Other configurations and number
of rings of packing may be used as the application requires.
