Edwards has expanded its range of nEXT turbomolecular pumps with two larger models that provide faster pumping performance and excellent compression ratios for longer cycle times and lower ultimate...
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...
The vacuum adapter is a convenient joint for quick connection of vacuum pipelines. The material is generally made of stainless steel 304. It is generally precision machined by CNC machine tools, wi...
After working for a long time on a Liquid ring vacuum pump, there will be some dirt on the outside or inside of the pump. In this case, we have to clean it. External cleaning is relatively easy, bu...
The scroll vacuum pump evolved from the scroll compressor. Its structural principle was first invented by the French engineer Cruex in 1905, but due to technological limitations at the time, it was...
