Trouble-free pumping in problem slurry sumps

2021. 7. 27.  For handling really abrasive slurries, pumps need more than just alloys with a high chrome content: the impeller and volute must be designed to reduce the impact of solids on the wear surfaces. With the help of 21st century computational fluid design tools, we have increased the abrasion resistance of Flygt slurry pumps in three ways:
