 When
the Mechanical Seal is replaced, the shaft is sealed at two
points. In addition to the
locking seal an O-Ring
Seal (A) just inboard from the seal is engaged.
This minimizes product loss during seal change and acts as
a backup for the main locking seal. The Mechanical seal
area is completely enclosed for protection from rain, dust,
freezing temperatures and other undesirable conditions. A
drain hole (B) is provided for seal leak detection.
Should complete seal failure occur,
product loss is restricted by the shaft end bearing and by
two additional close clearance rings. |
