CHALLENGES
The OEM liners used across four
centrifugal pumps had historically high
wear rates. With the supply chain
challenges during COVID, the site was
having a difficult time stocking enough
parts to keep the operation running.
PROCESS
2 trial liners were installed and monitored throughout their complete life cycle to determine actual wear performance. Statistical analysis compared old vs. new liner performance, with a 10-year cost simulation to validate the business case.
- Process Simulation
- Statistical Analysis
- Software Implementation
KEY METRICS
Based on the execution of the
identified recommendations, the following benefits were realized:
3.5X
Increase in impeller life.
$70K
Reduction in labor and material cost per year.
ACTIONS
- 10-year cost simulation completed to review financial impact.
- Updated work instructions to reflect material changes.
- Communication with relevant stakeholders on findings and updates.
- Updated CMMS to reflect spare part stock requirements.
- Expanded material changes to other pump applications.
OUTCOMES
Improved Impeller Life
Characteristic life increased from 1.75 to 6.2 months.
Decreased Material Consumption
The combination of a local supply chain and improved wear life reduced risk of facility downtime due to inadequate impeller stock.
