This is an automatically translated description

The basics of equilibrium and fluid motion in pipelines and supercharger elements are presented in terms of calculating the head losses on them and the features of their flow. The theoretical issues of calculating the main operating parameters of centrifugal pumps, their separate and combined operation when supplying liquid to a pipeline are considered, and rational methods of pump selection and methods of regulating their operating parameters are presented. Pumps and compressors of various types and designs used in water supply and sewage systems are described, their operating principles and technical characteristics are shown. Information is provided on new technical designs of some volumetric pumps.

The textbook is intended for students of higher education institutions studying in the field of “Water Resources”. It can be useful for students of other technical specialities, as well as specialists working in the field of water supply and sewerage, as well as heat and gas supply.
