Abstract:
1. Apparatus for controlling a pumping system, said pumping system comprising: a main pump; at least one auxiliary pump; a housing fitted to an exit of the main pump; a pressure transducer to detect a pressure; and a minimum flow detector to detect a fluid flow inside a pipe operatively connected to the main pump; said apparatus comprising: a frequency changer to regulate a performance of the main pump; and an electronic control circuit, operatively electrically connected to the pressure transducer and the flow detector, so that, based on the signals received from the pressure transducer and the flow detector, makes decisions to bring the at least one auxiliary pump into use or to take the at least one auxiliary pump out of use, or to keep the auxiliary pump in its present state, and sends a signal to the frequency changer for regulating the performance of the main pump, maintaining the pressure unchanged.
