Hydraulic Institute seeks qualified individuals to aid in ANSI review process

The Hydraulic Institute (HI), under the approval of the American National Standards Institute (ANSI), is seeking qualified individuals to participate in the review process of a newly completed standard for Rotodynamic Pumps for Pump Piping.

The standard, which provides piping requirements for rotodynamic pumps, was developed to educate users about the effects and interactions of inlet (suction) and outlet (discharge) piping on pump performance.  It covers the effects of piping on the apparent net positive suction head available (NPSHA) to the pump, the developed pressure of the pump, hydraulic and piping loads on the pump, noise, and vibration.

"This standard represents the culmination of efforts and input from manufacturers, users, and individuals involved in fluid dynamic tests," explained Gregg Romanyshyn, Technical Director for HI. "Data was provided by array of sources to substantiate inlet piping requirements."  Romanyshyn noted several significant highlights to the standard, including:

• Inlet velocity requirements
• Effects of piping-generated swirl
• Required straight pipe lengths
• Piping head loss methods
• Proper restraint for expansion joints and couplings

Individuals and organizations 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 interested parties who wish to review the drafts and will submit the list to ANSI in order to meet its open canvass requirements.

To participate in the ANSI/HI canvass, contact Joseph Latta, Technical Affairs, at jlatta@pumps.org or call (973) 267-9700 x15.

HI periodically introduces new standards based on industry needs. ANSI/HI Standards currently comprise over 1300 pages and 25 documents.

The 88-year old Hydraulic Institute, the largest association of pump producers in North America, serves member companies and pump users by providing product standards and forums for the exchange of industry information. To learn about membership in the Hydraulic Institute, prospective members are invited to call HI Executive Director Bob Asdal at (973) 267-9700. Information on the Hydraulic Institute, its services, standards, publications and meetings, can be found on the HI web site at www.pumps.org and www.pumplearning.org. Requests may also be faxed to (973) 267-9055 or mailed to: Hydraulic Institute 9 Sylvan Way, Parsippany, NJ 07054.
