water circulation vacuum pump
These cavities expand to intake gas and contract to compress it, with the compressed gas and water discharged into the tank for separation and water recycling. Capable of handling wet, dirty, or corrosive gases, it delivers a stable vacuum of 2–4 kPa (or 270–670 Pa with an ejector). Applied in chemical, pharmaceutical, food, and environmental industries for degassing, drying, and vacuum conveying.
