uid from an external source. Flushing liquid may
be taken from the pump discharge and supplied
through 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. Consult the factory if
flushing is required.
Bearings
Bearing housings are fully lubricated when
shipped from the factory. Check the constant level
oiler regularly and keep it full of oil. When lubrica-
tion is required, flip the transparent oiler cup open
and fill it with SAE No. 30 non-detergent oil.
Under normal conditions, drain the bearing hous-
ing once each year and refill with clean oil. Change
the oil more frequently if the pump is operated con-
tinuously 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.
