Summary
Maintenance Benefits
- Customer had to drain the basin and increase flow rate to other basins which required manual changes to the process
- Outfitting personnel for basin entry and removal of fibrous material is eliminated
- Disposal issues of fibrous material eliminated
Mechanical Benefits
- Increased up-time of your plant
- Reduces load on agitator system such as gears, bearings, motor, shaft, and impeller blades
- Reduced vibration and increased life of agitator
Process Benefits
- Increased process up-time and elimination of manual process changes
- Elimination of fibrous material on impeller maintains top to bottom flow pattern which improves solids suspension and blending uniformity in basin
- Reliable and consistent discharge within plant operating permit limits
