Warman Pumps used to produce a slurry pumping handbook with all the information necessary.
I am afraid they are rather rare, but it would be worth trying them.
They are now part of the Weir Group, so you may find they are more reluctant to spend money on general technical support literature...
How do I determine the size of syphon breaker pipe required on an axial flow pump to ensure it functions correctly
