The Hydraulic Institute (HI), the largest association of pump producers in North America, has announced the release of their newest standard, Rotodynamic (Centrifugal) Slurry Pumps for Nomenclature, Definitions, Applications and Operation (ANSI/HI 12.1-12.6-2005).
Believed to be the first of its kind, the standard was created to educate users on the basic needs and design requirements of slurry pumps and pipeline systems, including information on slurry pump types, slurry limitations, slurry types, slurry solids’ effect on pumps, pumping of froth, pump wear, and applications. In addition, the material provides requirements for wet-end and bearing housing shaft seals, establishes allowable nozzle loads, and provides a data sheet that can be used by purchasers and vendors to exchange information.
The standard establishes different classes of wear service, and provides information on the different types of slurry pumps available and guidelines of where they may be applied. For each class of wear service, the document indicates recommended slurry pump design, as well as selection and application standards, including minimum bearing lives and shaft deflection, maximum permissible operating speeds, how to determine maximum branch loads, and testing requirements.
The widely-accepted ANSI/HI Pump Standards contain over 25 documents, and include definitions, industry terminology, design, application, installation, operation, and maintenance guidelines. The standards are designed to help eliminate misunderstandings between the pump manufacturer, purchaser, and/or user, and to assist the purchaser in selecting the proper product for a particular need. All HI standards are ANSI approved, meaning that the American National Standards Institute board certifies that HI has met the requirements for due process, consensus and other criteria for standards approval.
