This standard was designed to provide design and application information for rotodynamic vertical pumps for various services, including principle features of this pump type and necessary precautions for proper use.

"This standard has been extensively reorganized with new figures, diagrams, and updated text," explained Gregg Romanyshyn, technical director for HI. "The document features a wealth of new information, including the application of couplings for solid shaft and hollow shaft motors, thrust bearing configurations, and variable-speed drives."

Romanyshyn noted several new sections that have been added to the standard, including vertical motors, parameters for driver selection, area classification, and motor performance characteristics.

Individuals and organizations 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 interested parties who wish to review the drafts and will submit the list to ANSI in order to meet its open canvass requirements.

To participate in the ANSI/HI canvass, contact Karen Anderson, technical affairs administrator, at kanderson@pumps.org or call 973-267-9700, ext. 23.
