(Figure 3)
The intermediate was fully lubricated when
shipped from the factory. Check the oil level regu­
larly through the sight gauge (58) and maintain it at
the middle of the gauge. When lubrication is re­
quired, add SAE No. 30 non‐detergent oil through
the air vent (18). Do not over‐lubricate. Over‐lubri­
cation can cause the bearings to over‐heat, result­
ing in premature bearing failure.
Under normal conditions, drain the intermediate
once each year and refill with clean oil. Change the
oil more frequently if the pump is operated continu­
ously or installed in an environment with rapid tem­
perature 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.
