Hydraulic Institute seeks reviewers for updated pump standard.
Press Release Summary:
Jul 02, 2010 - Hydraulic Institute, under approval of ANSI, is seeking qualified individuals in North America to participate in review process for draft of updated standard ANSI/HI 11.6 - Submersible Pump Tests. This revision requires that submersible pumps be guaranteed and tested as complete units. Standard does not identify individual sources of losses within boundary of submersible pump unit. It includes details that state how acceptance testing shall be performed and defines pump acceptance criteria.

Hydraulic Institute Seeks Reviewers for Updated Pump Standard: ANSI/HI STANDARD 11.6 - Submersible Pump Tests
Press release date: Jun 23, 2010
This revision of Submersible Pump Tests represents a major departure from all previous pump test standards since it requires that the submersible pump be guaranteed and tested as a complete unit. If pump efficiency or required pump power has been guaranteed, then the pump unit's wire-to-water efficiency or electric input power is guaranteed and tested, in addition to the required flow and head test.
The standard does not identify the individual sources of losses within the boundary of the submersible pump unit. When a manufacturer offers an efficiency guarantee for a submersible pump, or an input power guarantee, that guarantee encompasses the entire pump unit. This standard includes the details that state how acceptance testing shall be performed and it defines pump acceptance criteria. The overall pump efficiency can be calculated by dividing the output hydraulic power delivered by the pump by the electrical input power delivered to the motor. This standard explains to the purchaser that any attempt to calculate an individual element of the pump unit's overall efficiency (such as motor, cooling system, seals, bearings or hydraulic efficiency to name a few) can yield questionable data and shall not be used to determine whether a submersible pump unit is acceptable.
Individuals and organizations 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 verify its open and balanced canvass requirements.
HI Pump Standards are reliable, widely accepted references for anyone involved in pumps, including users, consultants, contractors, construction firms, manufacturers of pumps, seals, motors, instrumentation, controls, and pump software developers and systems integrators. HI periodically introduces new Standards based on industry needs. The HI's complete library of ANSI Standards for the pump industry are user-friendly and available in both electronic and print formats at the HI eStore: eStore.Pumps.org, or by calling the Hydraulic Institute's purchasing line at: 973.267.9700 Ext 118.
