Abstract

A method for controlling a pump unit for pumping liquid or suspension includes controlling a pump unit based on a determination of a combination of an inducer and a centrifugal pump at least on parameters of a total volumetric flow rate and pressure difference over the pump unit, and controlling the pump unit based on a rheology of a fluid to be pumped so that necessary fluidization parameters of the fluid are predetermined to enable operation of the pump unit, and the rotation speed of the inducer rotor or an output power of the inducer rotor is controlled to a desired volumetric flow rate.
