8. Ultra-High-Resistance to Strong Acids and Alkalis Model: A multi-purpose unit capable of pumping mixed liquids from the Hydrochloric Acid, Nitric Acid, Acid/Alkali-Resistant, Acrylic Acid, and Urea models; in addition to the Solvent Model, it can handle all six liquid types listed above; withstands temperatures up to 70°C

9. PTFE Strong Acid and Alkali Resistant Model (Reinforced): Versatile for pumping mixed organic and inorganic strong acids and alkalis; features a newly upgraded three-layer PTFE valve disc assembly for enhanced protection! Temperature resistance: ≤70°C

II. Safety Precautions

- Strictly prohibited from pumping liquids containing particles

- Except for the Ultra-High-Resistance to Strong Acids and Alkalis model, due to differences in pump head materials, other models must not be used for multiple purposes or to pump liquids of different media
