5. Make sure that everyone is clear, and then jog the driver long enough to determine that the direction
of rotation corresponds to the arrow on the bearing housing or close-coupled frame.
6. Lock out power to the driver.
Thrust bearing lubrication
WARNING:
Make sure to properly lubricate the bearings. Failure to do so can result in excess heat generation, sparks,
and premature failure.
Grease lubrication
This pump comes with a grease-lubricated duplex thrust bearing. The bearing is pre-lubricated at the
factory with a lithium-based grease. Regrease the bearing according to the schedule in the Maintenance
chapter.
Pure oil-mist lubrication
Pure oil-mist lubrication is an option only available on the API3171.
Flush the steady bearings
There are five 1/4-in. NPT pipe plugs on the standard support plate that you use to connect the flush
lines. Each plug connects with each of the five bearings. Pumps with less than five bearings still have five
plugs, but only the required number are connected to bearings.
1. Remove the plugs from the holes that are connected to flush lines.
2. Connect an external source of clean water to the taps.
The water source must be able to deliver 1 to 2 GPM to each bearing.
3. Turn on the water in order to begin the flush.
Sealed bearings
Sealed bearings have a lip seal above and below the bearing in order to keep grit out of the bearing. Sealed
bearings use a spring-loaded grease cup for lubrication. The bearings are pre-lubricated at the factory, but
the grease cups ship in a separate box in order to prevent shipping damage. Fill the grease cups with grease
and screw the cups into the taps that are connected to the bearings. Refill the cups with fresh grease as
needed. Frequently inspect the grease cups after startup in order to check usage and establish the best
relubrication interval.
