Abstract
This invention provides a method for controlling slurry pump performance to better operate the pump and increase system operating stability. Such control is achieved by determining the instantaneous pressure produced by the pump (and the internal specific gravity that goes along with that) and using this pressure value along with the overall total pipeline resistance to determine the optimal instantaneous operating speed of the pump. When the pump is controlled in this manner, the adverse cavitation, wear, and other effects on the pump and pipeline associated with unstable system operation can be reduced or avoided.
