Zirconia Ceramic Sleeve in Acidic Slurry Pumps for Flue Gas Desulfurization (FGD)
✅Key Advantages
1. Acidic Media Stability – The ADCERAX® Zirconia Ceramic Sleeve demonstrates weight loss below 0.01% after 72-hour immersion in pH < 2 sulfuric slurry. Its stable crystal lattice resists acid corrosion and prevents ionic leaching that weakens metal sleeves.
2. Dual Resistance to Abrasion and Scaling – Laboratory slurry testing shows wear rate under 10⁻⁶ mm³/N·m, maintaining inner surface polish and reducing gypsum scaling over 2,000 h of cyclic operation.
3. Thermal Durability in Continuous Operation – The sleeve retains >90% of its flexural strength at 1000 °C, avoiding microcracks from hot–cold slurry transitions common in FGD recirculation loops.
✅ ️Problem Solved
A European power plant replaced stainless-steel sleeves in FGD pumps that corroded within 45 days due to acidic slurry. After switching to ADCERAX® Zirconia Ceramic Sleeve, the pump maintained stable discharge pressure for over 12 months without measurable dimensional loss. Maintenance downtime dropped by 60%, and acid consumption for corrosion compensation decreased by 15%, proving strong cost reduction under emission control compliance.

Pre-Installation Checklist
1. Inspect for Visible Surface Defects
Examine all Zirconia Ceramic Sleeves for cracks, chips, or surface irregularities before use. Even minor defects can propagate under thermal or mechanical stress. Reject any components with visual non-conformities.
2. Ensure Clean and Dry Fitment Environment
Prevent dust, oil, and moisture contamination in mating areas to avoid stress points or misalignment during installation. Use lint-free wipes and compressed air when cleaning interfaces.
3. Verify Alignment and Sleeve Orientation
Match sleeve bore and length orientation with flow direction or mechanical axis. Misaligned placement can induce torsional stress or restrict flow, leading to early failure.
-
Assembly and Integration
1. Avoid Excessive Mechanical Force
Use press-fitting tools with controlled pressure and guided motion. Do not strike or hammer Zirconia Ceramic Sleeve directly, as this can cause microfractures invisible to the naked eye.
2. Use Support Rings or Dampers Where Applicable
In dynamic or rotating assemblies, consider soft-mounting options. Vibration isolation helps extend fatigue life, especially under cyclic loading or pulsed flows.
3. Torque Fasteners Evenly Around Ceramic Interfaces
Uneven torque distribution can cause asymmetric stress. Follow recommended torque sequences, especially in flanged or sealed sleeve assemblies.
-
Operational Best Practices
1. Avoid Sudden Thermal Transients
Rapid heating or cooling can create thermal shock. Ramp temperature changes below 10 °C/min where process control permits to preserve material integrity.
2. Monitor Fluid Cleanliness and pH Stability
Highly abrasive or unstable chemical fluids accelerate wear. Install inline filters or neutralization controls when using Zirconia Ceramic Sleeve in unbuffered or slurry-rich environments.
3. Document Service Cycles and Replace Predictively
Logging operational hours and peak condition cycles aids preventive maintenance. Set replacement thresholds based on wear trends, not just visible degradation.
-
Handling and Storage
1. Store in Original Packaging Until Use
The foam-layered packaging is designed to prevent impact and surface damage. Keep sleeves in protective crates until final assembly.
2. Avoid Stacking Without Isolation Padding
Direct contact between sleeves can result in surface abrasion or chipping. Use foam layers or cardboard sheets between stacked units.
3. Label and Rotate Inventory by Lot Number
Implement first-in, first-out (FIFO) handling for traceability. Record lot numbers on system logs to track performance trends.
