This kind of pump can be found in all areas of industry where vacuum is required, from atmospheric pressure up to 1×10-3 mbar (appropriately matched). Some examples are the food, electrical, mechanical, chemical industries and many others.
The main feature of these pumps is their use for the pumping of material which contaminates wastewater and their treatment of attendant liquids from the pump which makes them highly ecological. The same applies to vapour pumps where the purest recuperation is required. They are ideal for extremely short pumping cycles in large chambers.
