ANSI/HI Pump Standards, 2002 Release on CD-ROM
The Hydraulic Institute (HI) has just released a new CD-ROM of its latest pump industry standards, ANSI/HI Pump Standards, 2002 Release. Two new standards have been added: the American National Standards for Submersible Pump Tests (ANSI/HI 11.6-2001) and the American National Standards for Allowable Nozzle Loads on Centrifugal and Vertical Pumps (ANSI/HI 9.6.2-2001).
PARSIPPANY, NJ, August 30, 2002 – The Hydraulic Institute (HI) has just released a new CD-ROM of its latest pump industry standards, ANSI/HI Pump Standards, 2002 Release. Two new standards have been added: the American National Standards for Submersible Pump Tests (ANSI/HI 11.6-2001) and the American National Standards for Allowable Nozzle Loads on Centrifugal and Vertical Pumps (ANSI/HI 9.6.2-2001). This new CD replaces HI’s 2000 Edition Pump Standards. It also includes an updated Master Index of all ANSI/HI Pump Standards.
A more user-friendly version of encryption technology is featured with this CD. The new encryption program automatically performs an authorization process for the user – a process that used to require several steps to complete. While HI standards are encrypted for installation and for use on the computer on which they are downloaded, multi-user licenses are also available.
Partnering on Submersible Pump Tests Standard
Development of the Submersible Pump Tests Standard was a collaborative effort between the Submersible Wastewater Pumps Association (SWPA) and HI. SWPA and HI worked for more than three years to develop this test standard, which HI then reviewed and finalized through the HI/ANSI approval process. The standard applies to the testing of centrifugal submersible pumps that are driven by induction motors. It is limited to closed-coupled impeller pump/motor units, designed to operate submerged in liquid. Submersible pumps operating in either a wet-pit or dry-pit environment are included.
Especially beneficial to pump purchasers, users and manufacturers during the specification and testing process, the Submersible Pump Test Standard provides recommendations for proper test selection. Procedures for performance testing, hydrostatic testing, net positive suction head required (NPSHR) testing, submersible motor integrity testing, and vibration testing are all described in the document. Uniform methods of data recording and reporting are also presented.
The standard provides guidelines for situations in which the test facility is unable to test a rated speed due to limitations such as power, electrical frequency, or flow capacity. In addition, piping arrangements for wet pit performance testing and dry pit performance testing are illustrated.
Nozzle Loads Key to Proper Pump Installation, Operation
The Allowable Nozzle Loads Standard assists pump users and systems designers in determining appropriate flange and nozzle loads. It is proving of particular value to those using pumps in chemical process applications such as those that conform to ANSI/ASME B73 standards. The standard recommends allowable nozzle loads for the following types of pumps: horizontal end suction single stage, vertical-in-line single stage, axial split case single and two stage, end suction slurry pumps, and vertical turbine short set pumps.
Comprehensive in scope, the Allowable Nozzle Loads Standard provides details on nomenclature and definitions, criteria for loading allowances, and driver and coupling alignment. It also offers useful information on internal pump distortion, nozzle stress and pressure-temperature relationships. Nozzle load adjustment factors, alternate pump mounting techniques and specific nozzle loads for various ANSI/ASME B73 pumps are provided.
This latest CD-ROM, ANSI/HI Pump Standards, 2002 Release, designated by HI product code CD2002, is available for $1050.00 in PDF format from HI’s E-store at www.pumps.org. The complete set of HI standards is available in hard copy or in CD-ROM format with a comprehensive index of valuable hypertext links for easy reference. Purchasers of the 2000 Edition CD ROM will automatically receive the 2002 Release as part of their subscription service.
The 85-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.
