MAINTENANCE & REPAIR PAGE E − 10
Fill the pump casing with clean liquid. Reinstall the
fill plug (55) 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 or by a flow of fresh liquid from an ex-
ternal source. Flushing liquid may be taken from
the pump discharge and supplied through auxilia-
ry piping installed in the seal plate. Remove the
pipe plug (6) to install the auxiliary piping.
When handling abrasive or tacky liquids, supply
fresh lubricating liquid from an external source. Be
sure the liquid supplied to the seal is compatible
with the liquid being pumped, and that its flow is
controlled to prevent dilution.
Bearings
The pedestal was fully lubricated when shipped
from the factory. Check the oil level regularly
through the sight gauge (24) 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 (12). 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.
