ABSTRACT:
An arrangement for regulating fluid conditioning stations including a plurality of pumping devices, at least one fluid storage reservoir, at least one pressure transducer and regulating mechanism, the conditioning station providing a fluid at a certain pressure and flow for consumption. The pumping devices start and stop such that the pressure in the fluid storage reservoir or reservoirs is maintained between two limit values of pressure (the start pressure and the stop pressure). Only one pumping device is started when the pressure in the storage reservoir(s) reaches or exceeds the value of the start pressure or when the flow provided by the pumping devices in operation is less than the consumption flow. Only one pumping device is stopped when the pressure in the storage reservoir(s) reaches the value of the stop pressure or when the flow provided by the pumping devices in operation is greater than the consumption flow.
