ANSI/HI 1.1-1.2 is the starting point for knowledge-seekers interested in acquiring basic information on rotodynamic / centrifugal pump configuration and assembly. Recognized as a comprehensive A-to-Z learning tool on the fundamentals of rotodynamic/centrifugal pumps, users will quickly and easily locate detailed information on a number of different pump types: Overhung impeller/close coupled pumps Overhung impeller/separately coupled pumps Bearing/separately coupled/single stage pumps Between bearing/separately coupled/multistage pumps Turbine pumps Special effects pumps Refreshed and updated to address the pump industry's increasingly demanding needs, the new offering is a must-have Standard reference for every rotodynamic / centrifugal pump library. Consider the scope of the enriched and substantially expanded (up by 35%!) content: users will find definitions of pump parts; nomenclature; detailed cross-sectional illustrations reflecting current industry practices; enhanced family trees featuring icons and pump designations that are unique to each pump type; explanation of the relevance of specific speed and suction-specific speed to the different pump types, and details on how these values affect basic performance ...and much more. Added special features of the new---and improved--- Standard: alphabetical and numerical listings of pump parts, expanded list of definitions of pump operation, and explanation of pump icons accompanied by illustrations. This is an exceptionally well-crafted Standard with a clear focus on providing users of rotodynamic /centrifugal pumps with the latest "cutting-edge" fundamentals.
