The Hydraulic Institute (HI), Parsippany, N.J., under the approval of the American National Standards Institute (ANSI), announced Tuesday, June 9, that it is seeking qualified individuals in North America to participate in the review process for the draft of updated Standard ANSI/HI 9.6.3, Rotodynamic Pumps for Allowable Operating Region.

This Standard applies to:

• Rotodynamic (Centrifugal) pumps
• Rotodynamic (Vertical) pumps

The guideline applies to rotodynamic (centrifugal and vertical) pump types. It describes the effects of operating a rotodynamic pump at rates of flow that are greater or less than the rate of flow at the pump's best efficiency point (BEP).

Individuals and organizations located in North America directly and materially affected by this standard are asked to contact the institute. These parties include pump users and specifiers, producers, standards developers, government agencies and general interest groups, accord to the HI. The institute 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.
