Answer Posted / vidya
If the pump is filled with air instead of water, the air is too elastic, (too compressible) for the typically designed pump to work. An exception would be a self priming pump (which is more efficient at pumping air). However, Even a perfectly designed self priming pump can not draw water from more than 32 feet because of the limitation of atmospheric pressure.
