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 16:17. Gluconic acid lactone is discharged from the crystallization tank; the material is a viscous solid-liquid mixture, with the solid phase being the dominant component and only a small amount of liquid water present. The proportion of the solid phase 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!
Look for positive-displacement pumps online; gear pumps are generally used to transport fluids with high viscosity where the head pressure isn’t very high
Can an open impeller pump be used?
It has high viscosity and contains solids. Consider heating during transportation to enable better control of viscosity. For a pipe diameter of DN100, there is no issue in transporting highly viscous media; it is recommended to use a cam rotor pump, as it can handle the transport of solid-liquid mixtures. I am a manufacturer in this field, and I can help you select the appropriate model and develop a suitable solution for you
