(under subclass 65) Apparatus comprising a vertical column into which the liquid to be pumped enters, with means to inject a gaseous motive fluid below the level of the liquid accumulated therein which effects a mixed mass of reduced specific gravity to elevate said liquid with said gas.
SEE OR SEARCH THIS CLASS, SUBCLASS:
85+, for means for pumping a fluid which employs a means to aerate the fluid to reduce its specific gravity in combination with another kind of pump means (e.g., jet, etc.).
151+, for jet pumps which employ a motive fluid moving at a greater velocity than the fluid to be pumped thereby creating a vacuum or reduced pressure area to motivate the pumped fluid and wherein the motive fluid may subsequently become entrained with the pumped fluid.
