Hydraulic Institute Seeks Reviewers for ANSI Canvass Ballots

20.08.2020
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 the following updated standards: ANSI/HI 9.1-9.5 Pumps – General Guidelines, ANSI/HI 9.6.2 Rotodynamic Pumps – Assessment of Applied Nozzle Loads, and ANSI/HI 9.6.8 Rotodynamic Pumps – Guideline for Dynamics of Pumping Machinery.

The purpose of ANSI/HI 9.1-9.5 document:
This standard provides general guidelines for rotodynamic and positive displacement pump type classifications, materials of construction, airborne sound measurement, and procedures for decontamination of returned product.

The purpose of ANSI/HI 9.6.2 document:
This standard includes recommendations for assessment of applied nozzle loads for the following pump types. When specified by the user, pumps supplied shall conform to these requirements.

  1. Horizontal end suction single stage (ANSI/ASME B73.1 Specification for Horizontal End Suction Centrifugal Pumps for Chemical Process and B73.3 Specification for Sealless Horizontal End Suction Metallic Centrifugal Pumps for Chemical Process).
  2. Vertical in-line single stage (ANSI/ASME B73.2 Specification for Vertical In-Line Centrifugal Pumps for Chemical Process).
  3. Axially split one and two stage (BB1).
  4. Vertically suspended pump single casing discharge through column with diffuser and volute (VS1 and VS2).

The purpose of ANSI/HI 9.6.8 document:
Applies to rotodynamic pumps. This guideline describes and recommends the means to appropriately evaluate pumping machinery construction attributes and relevant site characteristics in order to determine the effects of dynamic performance on equipment life and reliability. It describes and recommends various levels of detailed evaluation and validation that are commensurate with the degree of equipment uncertainty and application risk.

Individuals and organizations who fit the user and producer category located in North America and are directly and materially affected by these standards are asked to contact HI to be included in the ANSI canvass list to review the drafts. This list will be submitted to ANSI in order to meet its open canvass requirements.
