The Ultimate Pump Solution for Severe Acid Service
เมื่อจัดการ sulfuric acid, hydrochloric acid, และ hydrofluoric acid, standard pump materials fail rapidly. These highly aggressive chemicals demand the exceptional corrosion resistance that only Hastelloy vertical turbine pumps can provide. Hunan Durafort Pumps has engineered its LC Series vertical turbine pumps with advanced nickel-based alloys to deliver unmatched performance and reliability in the world’s harshest chemical processing environments.
Whether you are operating a sulfuric acid production plant, a hydrochloric acid storage facility, a hydrofluoric acid alkylation unit, or managing acid waste recovery systems, Durafort’s Hastelloy vertical turbine pumps offer the durability, safety, and operational longevity your critical processes require.
Why Hastelloy for Sulfuric, Hydrochloric, and Hydrofluoric Acid?
Hastelloy C276: The Workhorse for Mixed and Chloride-Containing Acids
Hastelloy C276 is the material of choice for handling:
- Dilute sulfuric acid across a wide temperature range
- Mixed acids containing sulfuric acid with other corrosives
- Chloride-containing sulfuric acid waste streams
- Wet-process phosphoric acid with sulfuric acid contaminants
- Flue gas desulfurization (FGD) systems
- Chemical waste treatment facilities
Hastelloy C276’s high molybdenum and chromium content provides exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking—even in the presence of chlorides and oxidizing agents commonly found in acid processing streams.

Hastelloy B3: The Premier Choice for Pure Hydrochloric and Hydrofluoric Acid
Hastelloy B3 offers superior performance in:
- Pure concentrated hydrochloric acid (HCl) service
- Hydrofluoric acid (HF) storage and transfer
- Underground storage tank acid pumping applications
- Acid pickling lines in steel processing
- No-oxidizing impurity environments where other alloys fail
Hastelloy B3 is specifically formulated to withstand the reducing acid environments of pure HCl and HF, where even high-grade stainless steels and duplex alloys experience rapid corrosion. Its unique metallurgy provides excellent resistance to localized attack and uniform corrosion, particularly in applications where oxidizing impurities are absent.
