LUBRICATION – BEARING FRAME
The lubrication of the ball bearings will depend on speed,
load, ambient temperature, contamination, moisture, in-
termittent or continuous service and other factors. These
regreasing recommendations are general in nature and
are to be used with good judgment and consideration of
the pump service. The following is a suggested lubrication
interval chart:
Frame Size
2,200 RPM 1,800 RPM 1,200 RPM
8.5 AK Frame
5,000 hrs.
12.5 AK Frame
2,500 hrs.
To lubricate the ball bearings, remove the plastic covers
from the zerk fi ttings. Ensure that the zerk fi tting and the
end of the grease gun are clean. Use only a hand-oper-
ated grease gun with ball bearing grease as shown be-
low, or equal:
