7.2 Pump lubrication
• PACO Type LF pumps on horizontal bearing frames have
bearing that may be sealed for life (requiring no lubrication),
regreasable or oil lubricated.
.
• To lubricate regreasable bearings, remove grease drain plug
(if any) and filler plug. Add clean ball bearing lubricant until
grease appears at drain hole or along shaft. On units with
drain hole, all old grease can be purged out ahead of new. In
such cases, the drain should be left unplugged for several
minutes during pump operation to allow excess grease to be
forced out.
• Lubricate bearing frame bearings at intervals of one to three
months, depending on severity of environment. Pumps in a
clean, dry, moderate temperature (100 °F maximum)
environment should be regreased at three month intervals.
Too much grease can cause premature bearing failure-do not
overgrease.
• On those PACO Type LF Centrifugal End Suction pumps
ordered with oil lubricated bearings, Fig. 7. A regular oil
maintenance program must be enforced.
• After the first 200 hours of operation the oil should be
changed. To change the oil, remove the drain plug at the
bottom of the bearing cover and the filler plug (that also acts
as a vent plug) at the top of the housing. After draining oil,
replace the fittings and refill with an acceptable oil selected
from Table , “List of acceptable Lube oils,” on page 11. After
the first oil change, the oil should be changed again at 2000
hours and then at intervals of 8000 hours or once yearly,
thereafter.
