Problem
A vertical turbine pump remains in operation while vibration increases and delivered capacity declines, creating a maintenance decision before a complete outage occurs.
Assessment
RMS reviews motor condition, alignment, operating current, discharge pressure, vibration observations, shaft behavior, and available operating history before deciding whether removal and internal inspection are justified.
Service Scope
- Document pre-removal operating condition
- Inspect shafting, bowls, bearings, wear surfaces, and column components
- Replace or repair verified worn components
- Reassemble, reinstall, align the driver, and verify rotation
- Record post-service operating observations for future comparison
Technical Details
- Vertical turbine pump vibration and capacity symptoms
- Shafting, bowl, bearing, wear-surface, and column-component inspection
- Driver alignment and rotation verification
- Post-service operating observations for future comparison
Return-to-Service Standard
The service objective is stable operation with corrected mechanical condition and a documented baseline for future maintenance decisions.
