MAINTENANCE & REPAIR PAGE E - 12
Final Pump Assembly
Be sure the pump and power source are securely
mounted to the base and that they are properly
aligned. If used, removed the eye bolt used to lift
component parts.
Install the suction and discharge lines and open all
valves. Make certain that all piping connections are
tight, properly supported and secure. Open all the
valves in the suction and discharge lines.
Be sure the pump and power source have been
properly lubricated, see LUBRICATION.
Remove the fill cover assembly (93) and fill the
pump casing with clean liquid. Reinstall the fill cov­
er and tighten it.
Refer to OPERATION, Section C, before putting
the pump back into service.
LUBRICATION
Bearings
The pedestal was fully lubricated when shipped
from the factory. Check the oil level regularly and
maintain it at the middle of the glass in the oil cup
reservoir. When lubrication is required, unscrew
the glass from the base of the reservoir. Fill the
glass through the beveled tube with SAE No. 30
non‐detergent oil. When the glass is full, quickly
turn it over, inserting the beveled tube into the res­
ervoir base. Repeat as necessary until the oil level
is in the middle of the glass, then screw the glass
back into the base. Maintain the oil at this level.
When lubricating a dry (overhauled) pedestal, add
approximately 128 ounces (3,8 Liters) through the
reservoir piping. Do not overfill. Over‐lubrication
can cause the bearings to over‐heat, resulting in
premature bearing failure.
Under normal conditions, change the oil each
5000 hours of operation, or at twelve month inter­
vals, which ever occurs first. 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.
Seal Assembly
Check the seal lubricant before starting the pump
and periodically during operation. Fill the bottle oil­
er (32) with SAE No. 30 non‐detergent oil. Check
the oil level regularly. The oil level must be main­
tained above the oil level indicated (31).
Periodically clean and reinstall the seal cavity air
vent (14).
Power Source
Consult the literature supplied with the power
source, or contact your local power source repre­
sentative.
