Acidic Catalyst Dosing in Fine Chemicals
✅Key Advantages
1. Acid-Inert Flow Path — Zirconia maintains surface integrity in strong acids like HCl/H₂SO₄. Mirror polish Ra 0.02–0.05 µm limits adsorption and preserves ±0.25% dosing.
2. Stable Micro-Dosing — Stiff plunger (Elastic Modulus 220 GPa) and high strength (Flexural 1100 MPa) hold clearances under load. Repeatability remains within ±0.25% from μL to mL strokes.
3. Extended Service Interval — High hardness (88–90 HRA) and toughness (12 MPa·m¹/²) resist wear and crack growth. Typical lifetime extends 3–5× versus stainless plungers in acid duty.
✅ ️Problem Solved
A fine-chem line dosing acid catalysts saw weekly seal failures and variable yields. After switching to ADCERAX® Zirconia Ceramic Metering Pump, dosing held at ±0.25%, and service intervals moved from weekly to quarterly (≈3–5× longer). The stable micro-dosing reduced off-spec batches and cut maintenance interventions per quarter by more than half. Production ran continuously through campaign windows without corrosion-related stoppage.

Additive Injection in Lubricant Processing
✅Key Advantages
1. Abrasion-Resistant Plunger — Zirconia hardness 88–90 HRA limits groove wear from solid-bearing additives. Accuracy drift is contained to ±0.25% over long runs.
2. Load & Viscosity Stability — Elastic Modulus 220 GPa prevents plunger deflection in viscous oils. Metering repeatability stays within ±0.25% across common ISO VG blends.
3. Reliability in Continuous Duty — Flexural 1100 MPa plus low thermal conductivity 2.2 W/m·K reduce mechanical and thermal drift. Replacement cycles extend 3–5× compared with steel components.
✅ ️Problem Solved
A blending line injecting detergent and AW packages faced additive scatter that forced rework. With ADCERAX® Zirconia Ceramic Metering Pump, dosing variation tightened to ±0.25% under continuous duty, and plunger wear became negligible across campaigns. Rework batches dropped markedly and changeouts were aligned with quarterly shutdowns (3–5× longer intervals). Shipment schedules stabilized as viscosity targets were consistently met.

Disinfectant Injection in Water Treatment
✅Key Advantages
1. Chlorine-Compatible Dosing — Zirconia’s chemical inertness protects surfaces with hypochlorite and chloramine. Dosing precision remains ±0.25% across typical plant temperatures.
2. Anti-Fouling Smooth Surfaces — Ra 0.02–0.05 µm finish resists residue that disrupts stroke volume. Cleaning cycles shorten while repeatability stays at ±0.25%.
3. Electrical Safety in Automated Skids — Dielectric strength 24 kV/mm and resistivity 10¹⁴ Ω·cm support reliable integration near sensors and drives. Signal stability and control response are maintained.

A municipal plant struggled with disinfectant under/over-dosing and daily cleanouts. After installing ADCERAX® Zirconia Ceramic Metering Pump, stroke consistency held at ±0.25%, and fouling was minimized by the Ra 0.02–0.05 µm wetted path. Operators moved from daily to weekly flush routines, reducing labor and chemical swings. Compliance margins improved as residual control became steady across operating shifts.
User Guide for Zirconia Ceramic Metering Pump
The Zirconia Ceramic Metering Pump is widely used in demanding industries, and proper operation ensures both accuracy and long service life. This section provides practical guidelines from installation to storage, helping users reduce maintenance costs, improve dosing stability, and ensure safe daily operation.
-
Installation Guidelines
1. Always mount the pump securely to avoid axial displacement and radial misalignment. Unstable installation may reduce accuracy and cause seal wear. Follow alignment checks before startup.
2. Ensure that the inlet and outlet connections are properly fitted with leak-free joints. Small leaks in chemical or food applications can compromise product safety. Periodic connection checks are recommended.
3. Verify that the pump is positioned in a clean, vibration-free area. Environmental stability extends component life and reduces unexpected downtime in production lines.
-
Operating Conditions
1. Maintain liquid temperature within the recommended working range to preserve dosing accuracy. High temperatures beyond limits can affect zirconia stability. Monitor inline temperature sensors during operation.
2. Avoid pumping liquids containing large particles or high viscosity without pretreatment. Excessive load may cause premature wear on the plunger. Pre-filtration systems should be installed if needed.
3. Keep stroke adjustments consistent with process requirements to maintain ±0.25% dosing precision. Over-adjustment can reduce repeatability and impact batch consistency.
-
Cleaning and Maintenance
1. Rinse the pump body and components with compatible cleaning agents after each use. Residues of acids, bases, or additives may crystalize and obstruct performance. Regular flushing helps maintain reliability.
2. Inspect plunger surfaces and sealing parts for visible wear at scheduled intervals. Replace worn parts promptly to avoid leakage and dosing errors. Keeping spare kits reduces downtime.
3. Apply maintenance logs for service cycle tracking. A structured record helps identify patterns and extend overall lifetime of the pump.
-
Storage and Handling
1. When not in use, store the pump in a dry, cool environment. Moisture exposure can degrade sealing components and reduce electrical insulation strength. Protective covers are recommended.
2. Always handle the pump with shock-resistant precautions. Strong impact may damage zirconia components despite their high mechanical strength. Use padded supports during relocation.
3. Before long-term storage, ensure the pump is fully cleaned and dried. Residual chemicals may corrode fittings or cause contamination in the next application cycle. Proper preparation ensures readiness.
