Girdhar Paresh, Moniz Octo. Practical Centrifugal Pumps

IDC Technologies, 2005. — 250 p. — ISBN 0-7506-6273-5.Practical Centrifugal Pumps is a comprehensive guide to pump construction, application, operation, maintenance and management issues. Coverage includes pump classifications, types and criteria for selection, as well as practical information on the use of pumps, such as how to read pump curves and cross reference. Throughout the book the focus is on best practice and developing the skills and knowledge required to recognise and solve pump problems in a structured and confident mannerApplications
