Bearing lubrication
Precautions
WARNING:
Make sure to properly lubricate the bearings. Failure to do so can result in excess heat generation,
sparks, and premature failure.
NOTICE:
Avoid equipment damage. Refer to driver/coupling/gear manufactures IOM for instructions and
recommendations for lubrication.
Pumps are shipped without oil
You must lubricate oil-lubricated bearings at the job site.
Ring oil lubrication
Ring oil-lubricated bearings are standard. Bearing housings are supplied with constant-level
oilers and sight glasses. Make sure that oil rings are properly seated in the grooves in the shaft.
Pure or purge oil-mist lubrication
Pure or purge oil mist are optional features. Follow the oil-mist generator manufacturer's
instructions. The inlet and outlet connections are located on the top and bottom of the bearing
housing, respectively.
Oil volumes
Oil volume requirements for ball/ball
This table shows the required amount of oil for oil-lubricated bearings.
All frames in this table use a Watchdog Oiler, which has a capacity of 4 oz. (118 ml).

Oil volume requirements for sleeve/hydrodynamic type bearings
NOTICE:
Do not expose an idle pump to freezing conditions. Drain all liquid that is inside the pump and
the cooling coils. Failure to do so can cause liquid to freeze and damage the pump.
Avoid equipment damage. Assure there is adequate pressurized oil flow as the pump coasts
down.
The sleeve/hydrodynamic type bearing is a pressurized lubrication system where oil is flowed
into the bearing. This system does not have an oil sump. The system requires a flow rate of 0.5
gpm (0.12 m
3 /hr) for the sleeve bearing and 1.0 gpm (0.23m 3 /hr) for Kingsbury #5 and 2.0 gpm
(0.45 m 3 /hr) for Kingsbury #6 for the hydrodynamic thrust bearing at 15 psi (100 kPA).
Lubricating-oil requirements
Oil quality requirements
Use a high-quality turbine oil with rust and oxidation inhibitors with rated viscosity shown below
at 100°F (38°C).
