HI Seeks Reviewers for Draft of Updated ANSI/HI 2.1-2.2


The Hydraulic Institute (HI), under the approval of the American National Standards Institute (ANSI), is seeking qualified individuals in North America to participate in the review process for the draft of updated Standard ANSI/HI 2.1-2.2 Rotodynamic (Vertical) Pumps of Radial, Mixed and Axial Flow Types for Nomenclature and Definitions.

This Standard applies to rotodynamic (Vertical) pumps.

This standard is for types, nomenclature, and definitions of vertical turbine, mixed flow, axial flow vertical diffuser, submersible motor deepwell and short-set pumps, commonly defined as vertically suspended types VS0, VS1, VS2, VS3, VS6, VS7, and VS8, as well as vertical overhung impeller types VS4 and VS5 that are driven by vertical electric motors or horizontal engines with right-angle gears.

Individuals and organizations located in North America directly and materially affected by this standard are asked to contact HI. These parties include pump users and specifiers, producers, standards developers, government agencies, and general interest groups. HI is currently assembling a canvass list of all parties interested in reviewing the draft. This list will be submitted to ANSI in order to meet its open canvass requirements.
