5.6.4 Greased-for-life bearing lubrication
The bearing manufacturer fills greased-for-life bearings with grease and seals them at the factory. You do
not need to lubricate or seal these bearings. Refer to the Maintenance chapter for re-greasing and main-
tenance procedures for these bearings.
5.7 Pump priming
Potential for leaks or flooding. Make sure that you reinstall the drain plugs, check all joints for tightness,
and flange bolts for the proper torque. Failure to follow these instructions can result in property damage
and/or moderate personal injury.
Prior to filling the pump, install all plugs and blind flanges on casing and auxiliary piping. Make sure all
openings are sealed off prior to priming pump.
