A system for transporting a highly corrosive liquid solely by pressure differential without the need of mechanical pumps for transporting the corrosive liquid. The system includes a source of gas under pressure (78,82) and first and second corrosive liquid reservoirs (22,24) connected in parallel to the source via a valve (80) such that one or the other, but not both, may receive pressurized gas. A valve (20) connects one or the other, but not both concurrently, of the reservoirs to a point of use (10) of the corrosive liquid and is specifically designed for connecting the reservoir receiving the pressurized gas to the point of use. A valve (36) receives corrosive liquid from the point of use and directs the same to one or the other, but not both concurrently, of the reservoirs, and is specifically designed to provide the corrosive liquid to the reservoir not then receiving pressurized gas from the source. Air displaced from the reservoir receiving the corrosive liquid is directed to a scrubber (72) and then returned to the pressurized gas source for subsequent reuse.
