ANSI/HI 12.1-12.6-2011 Rotodynamic Centrifugal Slurry Pumps

This version of the standard has been superseded. PDF copies remain available for purchase.


This standard covers rotodynamic slurry pumps used for pumping and/or transporting mixtures of solids and liquids or so-called “slurries.” Slurries are often abrasive and, if not considered, may cause high wear and shortened life of pumps. Unlike clear water, slurries alter the performance of the pumps and cause wear to the wet-end parts. Below a certain velocity, some slurries also settle out in the piping, causing blockages. These differences are such that if they are not taken into account, the pumps will not work satisfactorily or not at all. For this reason, this standard includes information about slurries and their effects, which is necessary to select, apply, operate, and maintain slurry pumps of different designs and materials of construction.

Those engineers and consulting companies that work in mining and other industries that pump abrasives such as sand, rock, and slurry would benefit from purchasing this standard.
