ANSI/HI 12.1-12.6

This standard for Rotodynamic (Centrifugal) Slurry Pumps for Nomencalture, Definitions, Applications and Operation provides an update to the 2005 edition. It addresses a long-standing challenge in the wastewater pump industy for development and acceptance of a test standard written specifically for slurry pumps. The scope of this newly updated standard includes: Slurry pump typesTypes of slurriesSlurry limitationsSlurry solids effect on pumpsPumping of froth, pump wear, and applicationThe standard 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.

Significant updates in the 2011 edition include: pump icons and letter designation [e.g. (OH0), (VS5)] to help identify specific pump types, a principal symbols table, an expanded subscripts table, clarified datum elevations, and the Miller number versus Material Abrasivity curve.

The updated standard offers enhanced details and added content for seal flush plans. It also contains an improved dynamic sealing arrangement cross-section. In addition, the standard includes increased mathematical content and more comprehensive data tables.
