Acid & Alkali Resistant Media Transport Solution
When conveying sulfuric acid, hydrochloric acid, and chlorides in chemical and pharmaceutical industries, conventional metal gear pumps are prone to corrosion, causing seal failure or reduced metering accuracy. This solution centers on the HBA series non-metallic gear metering pump, using ceramic shafts, low-friction side plates, and corrosion-resistant sliding bearings to maintain 1% metering accuracy with pulsation-free output even in poorly lubricated corrosive media. For scenarios requiring back-pressure stability, it can be paired with a UPVC back pressure valve to further protect dosing accuracy from pipeline pressure fluctuations.

Features & Options

  • • Core equipment: HBA series strong acid/alkali resistant gear pump
  • • Optional: UPVC back pressure valve for dosing stability
  • • Applicable media: sulfuric acid, hydrochloric acid, chlorides
  • • Metering accuracy: ≤1%, pulsation-free output
