An unspared process pump.
A single centrifugal pump feeds a process unit. A bearing starts to wear. Rolling-bearing faults often show in vibration weeks before they fail.
- Week 0: Predict learns the normal vibration of the pump.
- Week 5: Vibration at the drive-end bearing starts to rise; Predict flags the change.
- Week 6: An engineer reviews the trend and plans a bearing change.
- Week 8: Bearing replaced in a planned stop, with parts and crew ready.
Worked example with stated assumptions, not a customer result. Real outcomes depend on the machine, the fault and the site.
- Bearing seizes, damaging the seal and shaft
- Leak risk and an unplanned unit slowdown
- Emergency call-out, parts rushed in
- Example: 24–48 hours to repair
- Bearing changed before it damages the seal
- Work planned into a normal shift
- Parts ordered at standard lead time
- Example: about 8 hours, planned
