preferred and/or beneficial. |

| If seal replacement
is necessary, wearing parts may be purchased separately, cutting
replacement cost in half. |
|
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.
