mounting feet, and secure the casing to the base
with the previously removed hardware.
Final Pump Assembly
Be sure the pump and power source are securely
mounted to the base.
Install the suction and discharge lines and open all
valves. Make certain that all piping connections are
tight, properly supported and secure.
Be sure the pump, pedestal and power source
have been properly lubricated, see LUBRICA­
TION.
Fill the pump casing with clean liquid. Reinstall the
fill plug (58) and tighten it.
Refer to OPERATION, Section C, before putting
the pump back into service.
LUBRICATION
Seal Assembly
The seal assembly is lubricated by the medium be­
ing pumped and no additional lubrication is re­
quired.
Bearings
The pedestal was fully lubricated when shipped
from the factory. Check the oil level regularly
through the sight gauge (31) 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 (17). Do not over‐lubricate. Over‐lu­
brication can cause the bearings to over‐heat, re­
sulting in premature bearing failure.
Under normal conditions, drain the pedestal 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.
Power Source
Consult the literature supplied with the power
source, or contact your local power source repre­
sentative.
