Hydrochloric Acid Pumps
The alloy-killer — most stainless steels are not in the conversation at all.
The properties that drive the choice
| Hazard profile | none of note |
|---|---|
| Concentration band in our data | 0–37% |
| In one line | Attacks ALL standard stainless steels and nickel-free alloys at any concentration. Fluoroplastics are the default economic choice. |
Which pump families serve it
At a reference duty (20 °C, 10 m³/h, 30 m). Your duty point may move the answer — run it through the tool below; the full report adds the alternatives worth quoting in parallel.
| Primary answer | Fluoroplastic-Lined Centrifugal Pump (PTFE/PFA/FEP lined) | Strong acids (HCl, dilute H2SO4, mixed acids) where no metal survives economically |
|---|---|---|
| Typical wetted materials | PTFE / FEP lined | |
Where the boundaries sit
- Chloride attack rules out common alloys; lined and non-metallic constructions dominate
- Fuming and mist mean the containment choice is a workplace-safety item, not only a leakage one
- Concentration and temperature move together in this medium — both belong in the enquiry
