Abstract:

A system for moving fluid from a lower elevation to a higher elevation and then returning fluid to its original level, or alternatively to a level above its beginning lower elevation comprising a variable volume chamber with a weighted lower component upon which the effect of gravity is greater than the weight of fluid and other negative effects of the fluid in the fluid supply line, thus creating a vacuum and drawing material into the chamber which has an upper section and lower section connected by means of a flexible membrane, and such chamber is capable of retaining fluid.
