TABLE 6a: Recommended Lubrication Periods.
•
To lubricate motor while running or at rest, remove
grease drain plug (if any) and filler plug on grease
fitting. Grease with clean lubricant until grease ap-
pears at drain hole or along motor shaft.

TABLE 7a: Recommended Bearing Grease For Motors
•
Table 7a lists the recommended types of grease for
motor lubrication. These types have all been thor-
oughly tested and should be used whenever possible.

GENERAL COMMENTS
WARNING: Operation of the unit without proper lu-
brication can result in overheating of the bearings,
bearing failures, pump seizures and actual breakup
of the equipment, exposing operating personnel to
personal injury.
•
PACO Type KP Double Suction Centrifugal Split
Case Pumps have bearings that may be "sealed-for-
life" (requiring no lubrication), regreaseable or oil-lubed.
•
Regreaseable bearings are packed with grease at
our factory prior to shipping. This initial filling of grease
is good for one year or 2000 hours of normal opera-
tion, whichever occurs first. After this time, a regular
grease maintenance schedule must be implemented.
(See Table 8a for recommended pump bearing
greases).

TABLE 8a: Recommended Bearing Grease For
Pumps.
•
Do not over-grease! Too much grease can cause
over-heating and premature bearing failure. The
bearing manufacturers recommend that the bottom
1/3 of the bearing be filled with grease. That is all!
On those PACO Type KP Centrifugal Split Case
•
Pumps ordered with oil lubricated bearings, (See Fig.
9a) a regular oil maintenance program must
be enforced. Pumps with oil lubricated bearings are
fitted with a transparent reservoir (85) (constant level
oiler) that maintains the oil level about the centerline
of the lower bearing. When necessary, the oil supply
in the reservoir of the constant level oiler must be
renewed. To refill, remove the reservoir and fill with
oil. After filling with oil replace into operating posi-
tion.

FIGURE 9a: Oil Lubricated Bearing Construction
• After the first 200 hours of operation the oil should be
changed. To change the oil, remove the drain plug
(16K) at the bottom of the bearing cover and the filler
plug (16B) (which 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 Figure
10a. 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.
