Based on the very successful German editions, this English version has been thoroughly updated and revised to reflect the developments of the last years and the latest innovations in the field.
Throughout, the author makes excellent use of real-life examples and highly praised didactics to disseminate his expert knowledge needed by vacuum technology users and engineers in their daily work at industrial plants, as consultants or in design offices. He covers in detail the most modern liquid ring pumps, with chapters dedicated to maintenance, explosion prevention and general procedures for safety at work with this technology. The whole is backed by a large repository of frequently needed technical data, unit conversions, formulae and current industrial, technical and legal norms without drawing on unnecessary complex or theoretical mathematics.
The result is the ideal hands-on introduction to vacuum technology, ranging from fundamentals to in-depth expert knowledge on liquid-ring vacuum pumps.
Helmut Bannwarth studied mechanical engineering at the Technical University of Ulm, Germany, completing his engineer's degree in 1963 with technical stream machines as subject. He began his professional career at Escher Wyss AG in Zurich, Switzerland, as a project and calculations engineer for Kaplan, Francis and Pelton type turbines and pumping turbines for hydroelectric power stations. After additional qualification as a welding engineer, he returned to Germany in 1968 to take on a position at the joint companies Lederle GmbH, Freiburg, and Hermetic-Pumpen GmbH, Gundelfingen. Since 1980 he has been General Sales Manager at the Lederle/Hermetic group, and is now also Authorized Representative for the company. He has previously authored two very successful German editions of this book as well as contributing to the book Foundations of Vacuum Science and Technology edited by J. M. Lafferty, and has published numerous scientific papers on pumps and vacuum systems.
