Sodium Hypochlorite Pumps
The disinfection workhorse — oxidising, off-gassing, and quietly destroying the wrong elastomers.
The properties that drive the choice
| Hazard profile | toxic, oxidising |
|---|---|
| Concentration band in our data | 0–15% |
| In one line | Environmentally hazardous, decomposes releasing chlorine gas — zero-leak drive recommended. Classic pitting agent for stainless steels and nickel alloys; titanium and fluoroplastics are the industry standard. |
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 Magnetic Drive Pump (sealless + lined) | Strong acids that are ALSO toxic/volatile — corrosion resistance plus zero leakage |
|---|---|---|
| Typical wetted materials | PTFE / FEP lined | |
Where the boundaries sit
- Off-gassing accumulates gas in the pump head — air-binding is the classic failure; the installation needs a venting plan
- Decomposition accelerates with heat, light and metal contact; storage and piping are part of the answer
- Oxidising attack on elastomers is the common materials failure — the wetted soft parts decide the service life
