Alkali Pump Selection Guide
Choosing the correct alkali transfer pump depends on the chemical properties, operating temperature, concentration, flow requirements, and solid content of the medium.
| Pump Type | Recommended Media | Main Advantage |
|---|---|---|
| CYF Fluoroplastic Pump | Strong alkali, concentrated NaOH | Maximum corrosion resistance |
| CYH Stainless Steel Pump | Industrial alkaline solutions | High efficiency and durability |
| CYQ Magnetic Pump | Hazardous alkali chemicals | Zero leakage operation |
| UHB Slurry Pump | Alkali slurry with particles | Wear and corrosion resistance |
Alkali Pump Materials Selection
Different alkaline media have different chemical properties. Factors such as alkali concentration, temperature, impurities, and operating pressure must be considered before selecting pump wetted materials.
For example, concentrated sodium hydroxide (NaOH) at elevated temperatures requires higher chemical resistance than low-concentration alkaline solutions. In applications involving abrasive particles, both corrosion resistance and wear resistance should be evaluated.
Changyu Pump provides alkali pumps manufactured with fluoroplastic lining, UHMWPE, and stainless steel materials to meet different alkaline chemical transfer requirements.
| Material | Recommended Application | Advantages |
|---|---|---|
| PTFE | Strong alkali chemicals, concentrated sodium hydroxide solutions | Excellent resistance to strong alkaline corrosion and chemical stability |
| FEP / PFA | High-temperature alkali applications | High temperature resistance and reliable chemical compatibility |
| UHMWPE | Alkali slurry containing solid particles | Excellent wear resistance and corrosion resistance |
| 316 / 316L Stainless Steel | Low to medium concentration alkaline solutions | High mechanical strength and good corrosion resistance |
| 304 Stainless Steel | General industrial alkaline fluids | Cost-effective solution for mild alkaline conditions |

PTFE / FEP / PFA for Strong Alkali Transfer
Fluoroplastic materials are commonly selected for highly corrosive alkali applications due to their excellent chemical stability.
They are suitable for:
- High concentration sodium hydroxide (NaOH)
- Caustic soda solutions
- Potassium hydroxide solutions
- Strong alkaline chemical circulation
Compared with conventional metal pumps, fluoroplastic lined alkali pumps provide better protection against chemical corrosion, reducing leakage risks and maintenance frequency.

When alkaline liquids contain solid particles, corrosion resistance alone is not sufficient.
UHMWPE (Ultra High Molecular Weight Polyethylene) provides:
- Excellent abrasion resistance
- Low friction coefficient
- Good chemical resistance
- Longer service life under particle-containing conditions
It is commonly used for:
- Alkali slurry transfer
- Metallurgical wastewater
