Performance Characteristics of Centrifugal Slurry Pumps ...

The ,performance, of two centrifugal slurry pumps has been reported for three solid materials having different particle size distribution (PSD) in terms of head, capacity, and power characteristics. The results have shown that the values of head and efficiency ratios are not only dependent on solid concentration but are also affected by PSD of the solids and properties of the slurry.

Sand-screen performance is often evaluated on the basis of two criteria: screen plugging and sand retention. Limitations of the Existing Approach. While the acceptance criteria for sand production and produced-particle size are well-defined and these factors are relatively straightforward to measure, screen plugging is defined differently by different investigators.
