LUBRICATION
Seal Assembly
The seal assembly is lubricated by the medium be-
ing pumped. No additional lubrication is required.
Bearings
The pedestal was fully lubricated when shipped
from the factory. Check the oil level regularly
through the sight gauge (32) and maintain it at the
middle of the gauge. When lubrication is required,
add SAE No. 30 non-detergent oil through the hole
for the air vent (18). Do not over-lubricate. Over-lu-
brication can cause the bearings to over-heat, re-
sulting in premature bearing failure.
NOTE
The white reflector in the sight gauge must be posi-
tioned horizontally to provide proper drainage.
Under normal conditions, change the oil each
5000 hours or once each year, 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.
Power Source
Consult the literature supplied with the power
source, or contact your local power source repre-
sentative.
