Product Description
Two Stage Watering Vacuum Pump uses water as a sealing liquid for generating a vacuum. It has two chambers/stages, each with a set of rotating vanes/blades that produce a vacuum by compressing and expanding the gas molecules and water vapor in the stages. The 1st chamber generates a partial vacuum, and the 2nd further compresses the gases for producing a higher vacuum level. The water is utilized for creating a seal between the chamber walls and the rotating blades that present gas from escaping. The Two Stage Watering Vacuum Pump is ideal for laboratory research, and chemical and pharmaceutical processing.
