What pump should be chosen for transporting viscous materials after gluconic acid lactone crystallization?

This post was last edited by Zhenfeng Online on 2018-1-20 at 16:21. Gluconic acid lactone is discharged from the crystallization tank; the material is a viscous solid-liquid mixture with a predominance of solid crystals, and only a small amount of liquid water is present. The proportion of solids is over 85%. Flow occurs by gravity from the top of the crystallization tank to the pump inlet, but due to the high viscosity, such flow is difficult to achieve. The dynamic viscosity of the material is 7500 mPa·s, its density is 1.4 kg/l. The transportation distance is 35 meters, the pipe diameter is DN100, the elevation difference for transportation is 15 meters, and the flow rate is 10–30 t/h. I would appreciate some advice from those who know more – which pump is the most suitable? Thank you!
Is there no expert in this section to answer this question?
Can screw pumps experience dynamic and static wear as well as the accumulation of dirty material? Polluted materials?
The range of options is quite wide~~~ gears, screws, or diaphragms can all be used~~~~
