ABSTRACT:
The present invention relates to automatically operative pumping equipment. A by-pass passage is installed branching off from the delivery pipe and meeting the vacuum pipe of a pump driven by an electric motor, the by-pass passage being equipped with pressure regulating means operable in response to the water pipe pressure at the pump delivery side, and by-pass passage regulating means controlled in response to a signal from a flow rate sensor on the pump delivery side, whereby the pressure on the pump delivery side is regulated by the by-pass regulating means and pressure regulating means thereby to automatically control pump operation in response to command signals from a pressure switch.
