LUBRICATION
Seal Assembly
(Figure 3)
Fill the bottle oiler (54) 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 3)
The pedestal was fully lubricated when shipped
from the factory. Check the oil level regularly
through the sight gauges (18)
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.
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.
