Keeping Your Solids in Suspension | Dynamix Agitators

Sep 11, 2014 ... Settling Rate. When sizing a mixer for applications that require solids suspension, we need to calculate the settling rate of the particles. ... Particle size; Solid concentration. The solid ... The higher the pumping the higher the mixing intensity, which is usually categorized as mild, medium, and vigorous. As the...

Flygt Slurry Pump Handbook - Xylem

Agitator. Standard hydraulic design makes slurry move at high velocity flygt hydraulic design reduces slurry velocity. Hydraulic design. Efficiency. Pumping slurry can ..... the particles is high. A standalone or a side-mounted mixer is an excellent option to resuspend the solids, when the sump is large or lacks sloping walls.

Trouble-free pumping in problem slurry sumps - Xylem

But there's a problem when you pump slurries: the angle of the vanes has the unintended effect of making solids slam into the volute wall head on. This leads to unacceptable levels of wear. However, with its long swept-back vanes, Flygt slurry impellers make the particles' flowlines follow the geometry of the volute, thus...

centrifugal slurry pump concentration limit testing and evaluation

In the pit pump operation, a vacuum at the suction inlet is used to draw solids into the pump. The higher the vacuum, the higher the solids concentration ingested. ..... highest solids concentrations, with larger particles moving in a partly sliding manner ...... The characteristics of the mixer, impeller, and cylinder used are.

ScatPump Submersible Slurry Pumps - PumpEng Australia

The ScatPump®'s agitator will keep particles suspended in the slurry while large, 30mm holes in the strainer have allowed virtually all of the solids to pass through. The pumping components of the ScatPump®, notably the agitator, impeller and wear plate are constructed of high-chrome iron, meaning the ScatPump® is...

It's in the rheology - Flow Control magazine

High concentration slurries, generally above 40-wt%, do not exhibit free settling behavior and fall into the “hindered” category. In order to design the most appropriate agitator, the slurry rheology needs to be fully understood. This includes particle and liquid densities, solids concentration (percent by weight solids), particle...

Pumping Slurry - Empowering Pumps

Mar 20, 2012 ... These applications usually require very large pumps that are subjected to high levels of abrasive wear of different types. • Gouging abrasion occurs ... In most slurry, the water tends to be used simply as a mode of transport for the solid particles that usually impart the damage to the pump. This is when the...

Slurry Pump Basics - Dragflow North America

STRAINER: the strainer prevents the entry of large particles that could get stuck inside the impeller zone causing damage to the pump. AGITATOR: Allows the pump to pick up sediments, putting solids on suspension. The way it works, due to the design of the vanes, forces a continuous high pressure flow of liquid towards...

Process Engineering | Avoid trouble with slurries | Chemical ...

Nov 1, 2006 ... Although colloids and very fine particles can be suspended with appropriate agitation, only a portion of the large particles will be suspended. Agitators should be ... Positive displacement pumps can handle very high solids concentrations (maybe as high as 95%), but add considerable cost to the project.
