High Vacuum Pumps: For Extremely Low Pressure Applications
High vacuum pumps are used in situations where very low absolute final pressure is required. They are capable of evacuating closed vessels and are suitable for long-term operation under vacuum, without atmospheric pressure. Special smoke cleaners are available to ensure their exhaust stays clean. The operating principle of high vacuum rotary vane pumps is similar to lubricated rotary vane vacuum pumps, but with an important difference: the stator of high vacuum pumps is immersed in lubricating oil to prevent air leaks. As a result, significantly higher pressures can be achieved than with other types of vane pumps. In addition, a ballast device is used to prevent condensation of water vapors. High vacuum pumps can consist of a single rotor-stator assembly (single-stage) or two rotor-stator assemblies connected in series. In the case of a double stage, the outlet of the first group is connected to the intake of the second group. The advanced technology of the high vacuum pumps makes them indispensable for various industrial and scientific applications, where precision and reliability are essential. Integrating dual stage technology, these pumps can effectively and efficiently reach extremely low pressure levels, critical for processes such as semiconductor manufacturing and other technologies where atmospheric contaminants can affect product quality and integrity. Carefully designed to operate continuously, even under severe operating conditions, our DVP pumps provide a robust solution for your most demanding vacuum needs.
