Hydraulic Institute Seeks Reviewers for Draft of Updated Ansi/HI 2.1-2.2 Rotodynamic Vertical Pumps of Radial, Mixed and Axial Flow Types for Nomenclature and Definitions

Parsippany, NJ – 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:

1. 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.

To participate in the ANSI/HI canvass, contact Karen Anderson, Administrator, Technical Affairs, at kanderson@Pumps.org or call (973) 267-9700 x123.

HI Pump Standards are reliable, widely accepted references for anyone involved with pumps, including users, consultants, contractors, construction firms, manufacturers of pumps, seals, motors, instrumentation, controls, and pump software developers and systems integrators.
