Pumping installation comprising a pneumatic pump for pumping a fluid and a supply system for supplying the pneumatic pump with compressed gas, the supply system comprising a source of compressed gas and a fluidic connection that fluidly connects the source to the pneumatic pump , the pumping installation also comprising a control system for controlling the supply of compressed gas to the pneumatic pump , said control system comprising: - a valve mounted on the fluidic connection and switchable between a blocking state, in which the valve prevents the flow of compressed gas between the source and the pneumatic pump , and a passing state, in which the valve allows the flow of compressed gas between the source and the pneumatic pump , the valve comprising a body internally defining a passage for the compressed gas, a valve mounted to move relative to the body between a closed position, in which it closes the passage , and an open position, in which it releases the passage , and a member for restoring the valve to its closed position, and - an automatic control system for automatic control of the valve , said automatic control system comprises a sensor for monitoring a parameter, and an actuator acting on the valve to automatically switch the valve from its passing state to its blocking state as a function of a signal produced by the sensor and representative of the parameter being monitored, the actuator being designed to retain the valve in its open position, the actuator having an active state in which it exerts on the open valve a force retaining the valve in its open position and an inactive state in which the actuator does not exert a retaining force on the open valve , characterized in that the actuator is designed to be in its active state when it is not supplied with electric current, and in its inactive state when is supplied with electric current. - a valve mounted on the fluidic connection and switchable between a blocking state, in which the valve prevents the flow of compressed gas between the source and the pneumatic pump , and a passing state, in which the valve allows the flow of compressed gas between the source and the pneumatic pump , the valve comprising a body internally defining a passage for the compressed gas, a valve mounted to move relative to the body between a closed position, in which it closes the passage , and an open position, in which it releases the passage , and a member for restoring the valve to its closed position, and - an automatic control system for automatic control of the valve , said automatic control system comprises a sensor for monitoring a parameter, and an actuator acting on the valve to automatically switch the valve from its passing state to its blocking state as a function of a signal produced by the sensor and representative of the parameter being monitored, the actuator being designed to retain the valve in its open position, the actuator having an active state in which it exerts on the open valve a force retaining the valve in its open position and an inactive state in which the actuator does not exert a retaining force on the open valve , characterized in that the actuator is designed to be in its active state when it is not supplied with electric current, and in its inactive state when is supplied with electric current. <EOS>
