Advantages of chemical positive displacement pumps
1. Strong media adaptability, meeting the special needs of the chemical industry.
The pump's wetted parts (the parts that come into contact with the media) can be made of PEEK, which is resistant to corrosion from strong acids (such as sulfuric acid and nitric acid), strong bases (such as sodium hydroxide), organic solvents (such as methanol and acetone), and highly oxidizing media, preventing damage to the equipment or contamination caused by reactions between the media and the pump.
2. Strong flow controllability, adaptable to precise measurement needs
3. Few wearing parts, easy maintenance
