Chemical-Resistant Diaphragm Vacuum Pump

耐化学隔膜真空泵

Corrosive vapors from acids and solvents need a pump with no vulnerable wetted materials. This chemical-resistant model uses PTFE and fluoropolymer throughout, with 2 or 4 heads and gas ballast, reaching 2–8 mbar at 20–120 L/min. Noise is 55–65 dB(A). It suits concentrators and aggressive filtration.

Ultimate vacuum: 2–8 mbar
Free-air flow rate: 20–120 L/min
Number of heads: 2 or 4
Wetted material: PTFE and fluoropolymer
Gas ballast: Yes
