Turn the impeller shaft by hand and check for any
scraping or binding and correct it before putting
the pump into service.
LUBRICATION
Seal Assembly
(Figure E−1)
Fill the bottle oiler (60) and seal cavity with approxi-
mately 85 ounces (2,5 liter) SAE No. 30 non-deter-
gent oil. Check the oil level regularly and refill as re-
quired.
Bearings
(Figure E−1)
The pedestal was fully lubricated when shipped
from the factory. Check the oil level regularly
through the sight gauges (31)
and maintain it at the
midpoint of the gauges. When lubrication is re-
quired, remove the vented plug (19) and add SAE
No. 30 non-detergent oil through the opening.
Clean and reinstall the vented plug. Do not over-lu-
bricate. Over-lubrication can cause the bearings to
over-heat, resulting in premature bearing failure.
NOTE
The white reflector in the sight gauge must be posi-
tioned horizontally to provide proper drainage.
Under normal conditions, drain the bearing hous-
ing once each year and refill with approximately 14
ounces (0,4 liter) of clean oil. Change the oil more
frequently if the pump is operated continuously or
installed in an environment with rapid temperature
change.
Monitor the condition of the bearing lubri-
cant regularly for evidence of rust or mois-
ture condensation. This is especially im-
portant in areas where variable hot and
cold temperatures are common.
For cold weather operation, consult the factory or a
lubricant supplier for the recommended grade of
oil.
