ABSTRACT:
An automatic pneumatic pumping system of the type using two or more pumping tanks which are filled in alternate sequence with liquid from a common source and are alternately purged by air pressure so as to effect a continuous and uninterrupted flow of the liquid into a common discharge line, wherein exhaust pumping air is used to create additional head within the liquid supply tanks and the creation of vacuum is used for system and auxiliary use. A preferred application of the system to marine vessels, for example a barge, is described (FIGS. 2-5), along with two special valves, a cargo valve of "top hat" design (FIG. 6) and a cargo inlet feed valve of a two-port wafer type (FIGS. 7A-C).
