Supplier's note

  1. Three Technical Breakthroughs:

    • Silicone Diaphragms: Withstands aggressive acids (pH 0-14), outperforming traditional rubber seals.
    • Stainless Steel Bodies: 30% higher corrosion resistance than plastic, ideal for harsh chemical environments.
    • Manual Precision Control: Enables ±1% flow accuracy in the Pro model, surpassing industry benchmarks.

  2. Optimal Version Selection:

    • Base Model: Suitable for general chemical labs or food processing with mild acids (e.g., pH 2-10).
    • Advanced Model: For industrial plants handling strong acids (e.g., sulfuric acid) or requiring up to 150°C operation.
    • Pro Model: Engineers in pharmaceutical or petrochemical sectors needing extreme chemical resistance (e.g., handling hydrofluoric acid) or ultra-precise dosing.

With silicone seals, you can ensure zero leakage in aggressive media. The Pro version’s triple-layer coating provides 50% longer lifespan than competitors in high-temperature applications. Pair its corrosion-resistant body with manual precision to achieve unmatched reliability.
