...machines for dry vacuum pumping. A. D. Chew,a M. Galtry, R. G. Livesey, and I. Stones. BOC Edwards, Crawley, West Sussex RH10 9LW, United Kingdom. Received 17 December 2004; accepted 23 May 2005; published 22 July 2005. The goal of a single dry pump capable of reaching high vacuum and itself exhausting...

...presents unique pumping challenges. This article discusses the factors leading to increased hydrogen use in these two processes, details the pumping challenges hydrogen presents for each, and highlights the vacuum pumping capabilities that are needed to resolve these challenges....

Vacuum is used to control the environment in many heat treatment processes and the vacuum pumping systems used may be simple or complex. This article offers practical recommendations to handle operational issues that can arise with these systems to optimize performance, reliability and safety...

Vacuum degassing (VD) and vacuum oxygen decarburisation (VOD) are the main processes in secondary steel making. The large volumes of dissolved contaminant gases arising and the generation of metallic fines and oxide dust require robust, high-capacity pumping equipment. Today's advanced vacuum dry...

Selecting the right vacuum pumping system for your heat treat application is a complex and challenging task with the realization that no single type of vacuum pump is likely to provide all the characteristics necessary to meet all your process requirements. Vacuum pump selection not only demands...

...was investigated. With reference to the results of that study, guiding principles will be presented for the design of a vacuum pumping system for use in low-pressure, high-gas-flow processing. Experimental setup used to evaluate pumps. A diagram of the experimental setup is shown in Figure 1...
