Pumping Hydrochloric Acid

Handling corrosive substances like hydrochloric acid demands precision and expertise. AxFlow stands at the forefront, offering a specialized range of pumps designed to safely and efficiently handle hydrochloric acid

Challenges in Pumping Hydrochloric Acid

Hydrochloric acid, a highly corrosive substance, presents unique challenges in handling due to its aggressive nature, particularly towards metals. Specialized materials and pump types are essential for safe and efficient handling.

How to Handle Hydrochloric Acid

  • Corrosion Resistance: Hydrochloric acid corrodes metals such as aluminium, cast iron, and stainless steel. Hastelloy offers high resistance, while titanium is partially resistant at lower concentrations.
  • Material Selection: Technopolymers like polypropylene, PVDF, and ETFE are highly resistant and suitable for temperatures up to 90°C, making them ideal choices for handling hydrochloric acid.

Solutions for Pumping Hydrochloric Acid

  • Air-Operated Double Diaphragm (AODD) Pumps: AODD pumps are designed with chemically resistant materials, ensuring safe transfer of hydrochloric acid without exposing the operator to the corrosive substance.
  • Plastic Centrifugal Pumps: Plastic centrifugal pumps, constructed from materials like polypropylene and ETFE, provide excellent corrosion resistance, making them suitable for hydrochloric acid applications.
  • Gear Pumps: Certain gear pumps with chemically resistant components can handle hydrochloric acid, ensuring precise and reliable fluid transfer.
  • Magnetically Coupled Models: Magnetically coupled pumps prevent leaks and contamination, enhancing safety and reliability when handling hydrochloric acid.

Hydrochloric Acid Applications

  • Chemical Manufacturing: Used in the production of various chemicals, including fertilizers, dyes, and pharmaceuticals.
  • Pickling Processes: Hydrochloric acid is employed for cleaning and etching metals in pickling operations.
  • pH Adjustment: Widely used for adjusting the pH levels in water treatment processes.
  • Laboratory Procedures: Hydrochloric acid finds applications in laboratory experiments and analyses, especially in the field of chemistry.

AxFlow offers a diverse range of pumps specifically designed to handle hydrochloric acid, ensuring efficient and safe operations in various industrial applications.
