ABSTRACT:
Disclosed are method and fluid lift pump for raising liquids through a bundle of substantially vertical lift tubes adapted to raise liquids even while submerged less than 50% of total lift height, the tubes having about the same length extending side by side, each tube having an inside diameter of less than about one inch. The lift tubes communicate at the lower end with a housing defining a chamber capable of being filled with liquid to be raised, and the lower portion of the housing includes means for injecting a lifting fluid into the liquid in the chamber. The injecting means comprise an injecting orifice, having an inside diameter no larger than about the largest lift tube inside diameter, positioned below the lower ends of the lift tubes by a specified distance depending on the cross-sectional area of the bundle and the number of injecting orifices. Bubbles of lifting fluid rise through the liquid in the chamber, enter the lift tubes, and form rising slugs of liquid separated by slugs of lifting fluid.
