  • Patent number: 8157534
    Abstract: The present invention refers to a control equipment for a pressure set, said pressure set being made up of a main pump and at least one auxiliary pump, characterized in that it comprises a housing fitted to the exit of the main pump, therewithin it is provided with: a pressure transducer; a minimum flow detector associated to the circulation pipe that is related to the main pump; a frequency changer to regulate the flow speed that is flowing through the hydraulic pipe that is connected to the main pump; and an electronic control circuit electrically connected to the pressure transducer, the flow detector, so that based on the signals received from them it sends a signal to the frequency changer so as to regulate the working parameters of the main pump and at least one auxiliary pump, keeping the pressure value unchanged throughout the workings of the pressure set.
