Oil-sealed rotary vane pumps
Rotary vane vacuum pumps are ideally suited for a wide range of low and medium vacuum applications such as general and chemical laboratory, analytics, freeze drying, process engineering and more. A rotary vane pump works via positive displacement, which is when volumes of air or gas are confined within a closed space and are compressed when the space is mechanically reduced.
