High Vacuum (HV) and Ultra-High Vacuum (UHV) levels can only be effectively and efficiently obtained by using a main pump that has the functional capabilities. Choosing which pump to use depends on a number of factors, such as noise/vibration, cost (initial and on-going), tolerance to contamination, footprint, maintenance schedules, and resilience to shock.
2020 marks the centenary of the development of the Holweck pump by the French physicist Fernand Holweck. As well as a stand-alone pump the Holweck design is used as a compound pumping stage in the widely employed TURBOVAC, nEXT and STP pumps. In this respect the Holweck design has been utilised to make significant advancements and improvements to the development of turbomolecular pumps over the last half century.
For business and organisations in the vacuum technology space, COVID-19 has changed the way in which they operate indefinitely – with many experiencing the effects in different ways. It has, without a doubt, been a harsh and challenging year, but signs of recovery are on the horizon as government-imposed lockdowns ease and many of these businesses and organisations resume (in some way) operations. .
In this blog, we explain the functional principle, operational requirements and application uses of Diaphragm Vacuum Pumps.
In December 19, 2019 we mentioned that dry screw pumps in food industry application are more often replacing wet pumps. We found a useful link about dry vacuum pumps in food packaging. Please follow https://blog.leybold.com/disrupting-food-packaging. In this blog, Jim Hupp, an experienced technician working in the Midwest USA explains the advantage of dry pumps compared to other pump types in this industry.
Given the situation with COVID-19, many questions are being asked about how vacuum technology (specifically mass spectrometers) can help with health diagnostics and research.
With this in mind, in this short blog we’ll explore how mass spectrometers can be used in the medical field to tackle pandemics like COVID-19.
Oil diffusion pumps have been the workhorse in high-vacuum pumping for many decades and remain the standard for industrial applications like brazing/soldering, E-Beam welding and large-area coating. Their investment costs are relatively low, and they can provide pumping speeds of up to 50.000 l/s. In this blog, we will explain the working principles of oil diffusion pumps, including how to apply and control them in vacuum systems, the typical dos and don'ts, and provide several application examples.
According to the Union of Concerned Scientists (UCSUSA) about 2,200 active satellites orbit our planet and an additional 100 are launched every year. Most of these satellites are used for telecommunication and, with GPS projects like the European GALILEO and the SPACE-X Starlink (which intends to bring internet connection to every spot on earth) on the horizon, their number will continue to grow.
The Annual Symposium of the American Vacuum Society is the world’s main yearly vacuum conference held in Columbus, Ohio from the 20th to 25th October 2019.
There were 27 parallel sessions in a wide range of topics and over 2500 registrants.
