A general overview of pumps and water lifters for irrigation, along with guidance for selecting, installing, and maintaining them without expert engineering services, is presented in this handbook. The handbook briefly surveys the sources of power that can be used to drive pumps and describes the various types of pumps, including pumps powered by humans and animals, propeller or axial flow pumps, and mixed flow and turbine pumps. Extensive criteria for selecting pumps and power units, such as the amount of water to be pumped, horsepower and efficiency, pump location, and specific speeds, are presented. Also considered are the use of pump components, semi-open and enclosed impellers, and electrical connections. Sections describing and providing guidelines on pump installation, intake structures, typical pump design, costs, and on evaluating existing pumping plants are included. The handbook features 7 technical appendices and a total of 32 tables and figures.
