PURPOSE:To continuously send a liquid under the pressure of gas, by providing a piping for supplying the gas to two liquid storage containers, and a piping for supplying the gas under pressure to only one of tanks in accordance with a detection signal from a level gauge. CONSTITUTION:A first piping 3 for supplying a liquid to a first and a second liqquid storage containers 1, 2, and a second piping 5 for supplying gas under prescribed pressure are provided. A shutoff valve is operated depending on detection signals from level gauges 11, 12 to apply the pressure of the gas to only one of tanks to push out the liquid through a third piping 9. Since pressurization is performed by a gas supply means, a centrifugal pump 41 without pressurizing action may be used. A filter means is not needed. This results in simplifying a whole equipment. |
