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 1.4 Rotodynamic (Centrifugal) Pumps for Manuals Describing Installation, Operation, and Maintenance. The standard applies to:

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

The purpose of the document is to:

1. Identify a standard format to be used when writing IOM’s along with the topics that will be covered in each section when deemed appropriate for the pump being addressed; and

2. Review and update as needed the existing ANSI/HI 1.4 document to conform to the newly identified format, as well as to address the needs of only horizontal centrifugal pumps.

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 at or 973 267-9700, ext. 123.
