Phosphoric Acid Pumps
Moderate acid, frequent solids — wet-process phosphoric arrives with gypsum and fluorides attached.
The properties that drive the choice
| Hazard profile | none of note |
|---|---|
| Concentration band in our data | 0–85% |
| In one line | Pure H3PO4 is moderate; wet-process (fertilizer grade) acid contains chlorides/fluorides that sharply increase aggressiveness — state the source. |
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 | End-Suction Centrifugal Pump (ANSI B73.1) | Clean or lightly contaminated fluids, moderate duty, flows ~2–400 m³/h |
|---|---|---|
| Typical wetted materials | Polypropylene (PP), Stainless Steel 316L, PVDF, Duplex 2205, PTFE / FEP lined, Hastelloy C-276 | |
Where the boundaries sit
- Pure phosphoric is easy; wet-process acid carries solids and fluorides — say which one you have
- Fluoride impurities attack materials that pure phosphoric does not
- Solids plus acid is an abrasion-corrosion problem; the pump type follows the solids
