SUCTION VELOCITY OF SLURRY PUMP
- Thread starter arsmith

Hi,
velocity = flow / Area
flow [m3/sec]
Area = cross sectional pipe area = 0.25 * pi * Di^2
Di = internal diameter of the pipe.
The inlet flow of such pumps should be lower than 2 m/sec and the inlet pressure should be high enough to avoid cavitation.
Hope this helps,
MVD

I dont believe that you can define the inlet velocity so tightly. What of the slurry is iron ore? You will end up with settling.
Suggest you contact GIW. They have a research centre for testing slurries. They also make availble some of their reseach papers. They also have software known as Slysel which is inexpensive although a bit cludgy to use. They publish a book by Wilson, Addie and Clift that will give you the design parameters. Its titled Slurry Transport Using Centrifugal Pumps. One source is
Another good source is the BHRA in the UK or the Atomic Energy Authority AEA in the UK. I believe both have been privatised and their technical papers are available from their website.

Two good sources of velocity information for slurry and sludge pumping can be found in:
Addie,G.R., "Slurry Pump Selection Considerations", Pumps and Systems Magazine, Oct.1993.pp.32-39
P&SM Staff, "Sludge Handling-Guidelines for the Tough Stuff", Pumps & Systems Magazine, June 1994, pp.38-41
The first gives, in Fig. 3, nomograms for velocity at limit of stationary deposition attributed to:
Wilson,K.C., "Effects of Solids Concentration on Deposit Velocity", Journal of Pipelines, 1986, pp.251-257
The second recommends that "sludge velocities should be kept above 4-5 ft/sec to avoid sedimentation in the line and reduce grease buildup". This article provides a comprehensive Sludge Services Applications Chart for various %solids including pump type selection and relative severity of in-service abrasion and plugging.
