Fluorine lined pump solutions are essential for safely handling strong acids, alkalis, solvents, and other aggressive fluids. Designed with a corrosion-resistant fluoroplastic lining inside a metal body, these pumps are widely used in chemical processing, electroplating, wastewater treatment, pharmaceutical, and semiconductor industries.
Choosing the right fluorine lined pump depends on your specific operating conditions, including chemical type, temperature, flow rate, installation layout, and whether the system requires continuous or intermittent operation. This guide covers five reliable options from Changyu Pump, each suited to different industrial scenarios.
What Is a Fluorine Lined Pump?
A fluorine lined pump combines the mechanical strength of a metal casing with the chemical resistance of a fluoroplastic lining — typically PTFE, PFA, or FEP. The lining protects the pump’s internal components from corrosive media, allowing it to handle acids, alkalis, and solvents across the full pH range (0–14).
Common lining materials include:
| Материал подкладки | Диапазон температур | Лучшее для |
|---|---|---|
| PTFE | Up to 260°C | Strong acids, solvents, ultra-pure media |
| PFA | Up to 260°C | High-purity acid, semiconductor use |
| FEP (F46) | Up to 200°C | Pickling fluid, corrosive acid transfer |
| PVDF | Up to 140°C | Chlor-alkali, electroplating, wastewater |

Frequently Asked Questions (FAQ)
Q1: What is the difference between a fluorine lined pump and a full fluoroplastic pump?
A fluorine lined pump has a metal casing with a fluoroplastic lining inside, combining structural strength with corrosion resistance. A full fluoroplastic pump is made entirely of fluoroplastic, offering higher purity but lower mechanical durability. Fluorine lined pumps are better suited for heavy industrial use.
Q2: Can fluorine lined pumps handle hydrofluoric acid?
Да. PTFE и PFA lined pumps are resistant to hydrofluoric acid. For toxic media like hydrofluoric acid, a sealless magnetic drive pump such as the CYQ Series is recommended to eliminate any leakage risk.
Q3: Can fluorine lined pumps handle solid particles?
Нет. Fluorine lined centrifugal и насосы с магнитным приводом are not suitable for media containing hard solid particles, as particles can damage the lining over time. A slurry pump or UHMWPE-lined pump would be a better choice for particle-laden media.
Q4: How long does a fluorine lined pump typically last?
Service life depends on the chemical concentration, temperature, and operating frequency. Under normal conditions with compatible media and proper installation, a well-maintained fluorine lined pump can last several years. Avoid dry running and always confirm chemical compatibility before operation.
Q5: Is a fluorine lined pump suitable for high-temperature applications?
It depends on the lining material. FEP supports up to 200°C, while PTFE and PFA support up to 260°C. For applications above 120°C, PFA lining is recommended. Always verify the temperature rating before selecting.
Q6: Do fluorine lined pumps require special maintenance?
Routine checks on the mechanical seal, shaft alignment, and lining condition are recommended. Magnetic drive models require less maintenance since there is no mechanical seal to replace. Avoid dry running in all cases, as it can damage the lining and bearings quickly.
Q7: Can I use a fluorine lined pump for both acids and alkalis?
Yes. PTFE, PFA, and FEP linings cover the full pH range (0–14), making fluorine lined pumps suitable for both acid and alkali media. Always verify the specific chemical compatibility, especially at high concentrations or elevated temperatures.
Q8: What certifications or standards should I look for when sourcing a fluorine lined pump?
Look for pumps that meet ISO, GB (Chinese National Standard), or CE certification. Confirm that the motor protection rating (IP55 as standard) and flange dimensions match your application and regional requirements.
