Description: ABSTRACT For many pumping systems appears the problem of the automatic adjustment of the operating point correlated with the requirements of the water supply. In the conditions of our days equipments the adjustment of the operating point can be done so that the pump efficiency to be maximum and the energy consumption to be minimum. The results presented in the paper were obtained from a test facility at the Hydraulic Machinery Laboratory that contains a pump with variable rotational speed, a real time computerized data acquisition system for all the measured parameters and professional software for adjusting the rotational speed of the pump depending on the requirements imposed by the consumers. The pump efficiency is monitored in real time using the thermodynamic method, with the P22 measuring equipment. The efficiency is determined using the temperatures measured upstream and downstream the pump, as well as the measured upstream/downstream static pressure increase. The professional software commands the adjustment of the rotational speed so that the operating point is optimum with respect to the energetic consumption and the pressure value to the consumers to be maintained in the initial recommended limits.
