Since the control signal for the pump is always the same, there is no need to change the software in order to adapt the machine to different conveyor heights or different concrete textures. The other components of the open hydraulic circuit are fed by a HPR 55-02 self-regulating pump which is also very silent due to its pulsation damping SPU unit.
