The Hydraulic Institute has announced the release of the new Rotodynamic Pumps – Guideline for Dynamics of Pumping Machinery (ANSI/HI 9.6.8–2014).

The new 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.

This guideline:

  • Includes what analysis is appropriate to specify or utilise for proper evaluation of new pumping equipment, prior to design or field installation;
  • Explains what analysis is needed to make an accurate assessment of existing pumping equipment installed in the field;
  • Ensures that any upgrades, rerates, or field modifications are done in a manner that will validate contemplated equipment design and field modifications;
  • Recognises the economics associated with analysis to different level requirements;
  • Prepares readers for dynamic characteristics of pumping equipment that might be significantly influenced by the installation, including piping configuration, mounting arrangement, or drive system;
  • Explains how to utilise the decision matrix that includes the uncertainty values, risk number, and RUN value to arrive at the suggested level of analysis;

This standard is now available for purchase in the HI eStore.
