Abstract
The liquid pump includes an inner and an outer tube. The inner tube can have a distal end that is positioned within an interior volume of the outer tube. A conical filter is on the distal end of the inner tube. A gas pump provides compressed air which is output through a plurality of inner tube holes on an inner surface of the inner tube on a distal portion of the inner tube and a plurality of annular space holes which are adjacent to an annular space between the inner tube and the outer tube.
