APPLICATION
Chemical plants — reagent dosing & injection
Small, repeatable flows that must hold against changing back-pressure — metering pumps, dampeners and relief design.
The typical duty
| Fluid | Sodium Hydroxide (Caustic Soda, ≤50%), 30% |
|---|---|
| Temperature | 25 °C |
| Flow | 0.5 m³/h |
| Head | 80 m |
| Viscosity | ≈ 3 cP |
| Conditions | dosing duty |
What the selector says at this duty
| Primary answer at this duty | Metering / Dosing Pump (diaphragm type) — Precise low-flow dosing (up to ~1 m³/h), chemical injection |
|---|---|
| Typical wetted materials | Polypropylene (PP), Cast Iron, Carbon Steel, Stainless Steel 304, Stainless Steel 316L, PTFE / FEP lined, Monel 400, Hastelloy C-276 |
The answer above is the tool's own output at the duty shown — run your actual numbers through it; your duty point may move the answer. The full report adds the alternatives worth quoting in parallel.
What to watch
- Accuracy claims belong to defined conditions
- The check valves are the wear items
