1. A method of monitoring operation of a positive displacement concrete pump having an inlet for receiving concrete and an outlet at which concrete is delivered under pressure, the method comprising:

  • sensing a parameter which bears a known relationship to an actual volume of concrete delivered under pressure from a material cylinder of the pump;

    determining velocity information as a function of the parameter sensed, the velocity information being related to a velocity of concrete delivered under pressure from the material cylinder of the pump; and

    predicting wear on pump components as a function of the determined velocity information.
