MAINTENANCE & REPAIR PAGE E - 9
Pump Reassembly
Install the seal ring (28) onto the shoulder inside
the pump casing (1). Install the casing gasket (5)
over the studs (23) in the pump casing. Remove
the hardware temporarily securing the seal plate
the the pedestal and slide the pump housing over
the vane plate. Be careful not to damage the seal
ring. Secure the pump casing to the seal plate and
pedestal with the nuts (22).
Final Pump Assembly
If either the suction or discharge flanges (4 and 34)
were removed, reinstall the gaskets (6 and 35) and
secure them to the pump casing with the previous­
ly removed hardware.
Install the suction and discharge lines and open all
valves. Make certain that all piping connections are
tight, properly supported and secure.
Fill the pump casing with clean liquid. Reinstall the
fill plug (36) 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. Under normal conditions, remove
the vented plug (8) and add one shot of No. 0 lithi­
um base grease from a grease gun after each 250
hours of operation or once each month, whichever
comes first. Do not over lubricate. Over lubrication
can cause the bearings to over heat, resulting in
premature bearing failure.
There are no provisions in the bearing cavity to
drain or flush the lubricant. The pump and pedestal
must be disassembled to completely clean and
maintain this cavity.
Under normal conditions, change the grease after
each 5000 hours of operation, or at 12 month inter­
vals, whichever comes first. Change the grease
more frequently if the pump is operated continu­
ously or installed in an environment where variable
hot and cold temperatures are common.
When lubricating a dry (overhauled) pedestal, fill
the cavity with approximately 1/3 lb. (0,15 kg.) of
grease.
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.
