Application experts provide technical leadership for ANSI/HI Standards

Xylem’s Paul Ruzicka, chief mechanical engineer, and James Roberts, chief product engineer, were recently honored by the Hydraulic Institute for their technical leadership and contributions in the creation of new ANSI/HI Standards for pumps.

The Hydraulic Institute (HI), under the approval of the American National Standards Institute (ANSI), recruits technically qualified individuals from North American companies that are directly and materially affected by the standard to participate in the review process.

ANSI/HI standards are reliable, widely accepted references for anyone involved in the pump industry. Those involved can include users, consultants, engineers, contractors, construction firms, pump manufacturers and pump software developers and systems integrators. HI periodically introduces new standards based on industry needs.

Ruzicka, an active HI committee chair, has been an active member of the Institute for 21 years and was recognized for his work on two standards. The first was “Rotodynamic Pumps Guideline for NPSH Margin, ANSI/HI 9.6.1-2012,” which establishes margins over NPSH3 that will lead to acceptable pump performance and service life. The second was “Rotodynamic (Centrifugal and Vertical) Pumps - Guideline for Allowable Operating Region, ANSI/HI 9.6.3-2012.” This standard provides guidance for determining the Allowable Operating Region (AOR) and Preferred Operating Region (POR) for rotodynamic pumps as related to the Best Efficiency Point (BEP) of each pump.

“Seeing the efforts of all the members that work to drive the standards to completion and to publication is truly satisfying,” said Ruzicka. “I’m proud to be a member that is part of the core team and grateful for the opportunity made available to me by Xylem to be a HI member.”

James Roberts was also honored by the HI for his contributions to three standards committees. He has participated in more than a dozen HI committees in his 18 years of membership. Roberts was recognized for his contributions as a member of the committee that developed “Rotodynamic Pumps for Pump Intake Design, ANSI/HI 9.8-2012.” This new version represents a significant update with twice the content as the 1998 version.

Roberts also joined Ruzicka on the “Rotodynamic Pumps Guideline for NPSH Margin, ANSI/HI 9.6.1-2012” and “Rotodynamic (Centrifugal and Vertical) Pumps - Guideline for Allowable Operating Region, ANSI/HI 9.6.3-2012.”

 “Working with the other members of the HI committees is very rewarding. It’s been a great way to learn and grow from others experiences. Most of the members have many years of experience in the pump world,” Roberts noted.
