Mechanically Driven Diaphragm Pumps for Use with Gases

Whether in medical technology, environmental protection/analysis, in the laboratory or process engineering, many applications are today unthinkable without the use of mechanically driven diaphragm pumps for gases. Their particular properties such as oil-free, maintenance-free and uncontaminated operation make them suitable for numerous fields of application. Despite their wide distribution, they are treated only marginally, if at all, in the general literature and, up until now, there has been neither a general account nor a comprehensive summary account of these pumps.

The intention of this book is to fill this gap and provide an overview of the diaphragm pumps with mechanical drive. In addition, examples of applications and advice concerning selection of the right pump are included in the subject matter.

This book will serve to inform and stimulate both the engineer constructively working on design plans, and the engineer undergoing training.
