Abstract: There is a great deal of misinformation in the industry on pumping high density, viscous slurries. These misconceptions become "accepted truths" as time goes on and at best hinder, and at worst stop, the implementation of appropriate technology.
2016-6-17 · hydraulic efficiency. When pumping slurries the medium moves faster than the solids. The result is very high wear rate. The Flygt impeller has a more back swept design than conventional impellers, which ensures a more homogenous flow between the vanes. This minimizes the separation of solids from the carrier liquid, leads to high hydraulic ...
2008-7-5 · Important factors for submersible pump hydraulic parts: • Efficiency • Wear • Agitator Efficiency Pumping slurry can cause a severe reduction in the hydraulic efficiency of a pump. The Flygt impeller is designed to minimize this drop. Higher pumping efficiencies also correlate with lower wear rates. Wear Experience shows that the design ...
2006-11-1 · Nozzles should have the capability of either back flow or solids-free liquid injection after power failures. Pumping should be stopped until the suspension is restored unless the pump is designed for such a duty. Positive displacement pumps can handle very high solids concentrations (maybe as high as 95%), but add considerable cost to the project.
