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.Sleeve/ball bearings are optional. 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 volume requirements for sleeve/Kingsbury type bearings
The sleeve/Kingsbury 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 (0.23 m 3 /hr) for the Kingsbury 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).
