ANSI/HI Standards for Nomenclature and Definitions have historically been subdivided into ANSI/HI 1.1-1.2 Rotodynamic
Centrifugal Pumps for Nomenclature and Definitions and ANSI/HI 2.1-2.2 Rotodynamic Vertical Pumps for
Radial, Mixed and Axial Flow Types for Nomenclature and Definitions. The demarcation between the two categories
is determined by the arrangement of the hydraulic configuration (impeller, casing, bowl, or diffuser). However,
in each case they have shared physical features and hydraulic functions that are better addressed together rather
than separately. Every effort has been made to include and expand all the information contained in these previous
standard into a single resource. The result is this single source of nomenclature and definitions information for the
pump community.
