Abstract
The dual injection airlift pump has a hollow tubular body through which the liquid being pumped passes upward from the lower intake end to the upper outlet end. Air or other gas is injected into the liquid in the pump body, the less dense gas adding buoyancy to the liquid and entraining the liquid to rise toward the outlet end. The dual injection airlift pump includes two air injection stages, with the first or lower stage having a perforated interior sleeve allowing the gas to pass therethrough to be injected radially into the liquid. The second, upper stage has an impervious sleeve defining a gap between the sleeve and the interior surface of the pump wall, the lower end being sealed and the upper end open. Air is injected between the sleeve and pump wall, the air exiting at the upper or downstream end in an axially peripheral flow pattern.
