This series of Roots-type vacuum pumps cannot be used alone. It needs to be used in series with the pre-stage vacuum pump to increase the pumping rate of the pre-stage vacuum pump when the pressure...
Many vacuum process installations are equipped with a Roots pump on top of the pre-stage pump, both to increase the pumping speed and to improve the vacuum. However, the following problems are ofte...
Rotary vane vacuum pumps are used as oil sealed pumps most of the time. During the use, some oil and gas will be expelled together with the pumped gas, resulting in oil spray. Therefore, rotary van...
Achieving and maintaining high vacuum or ultra-high vacuum (UHV) requires surfaces that are exceptionally clean and inert. Acid cleaning (or pickling) is a fundamental, specialized process applied ...
