The Compressor Pumps work on the principle of difference of two inter-connected water columns; the heavier one, balancing over the lighter one on operation. The compressed air is pumped down into the well and gets mixed with water in the delivery pipe as very fine air bubbles by the Air-distributor installed at the end of the air pipe line. This air-water mixture having a low density than the surrounding water column rises in the discharge pipe. On continuation of this process, water is pumped out through the discharge pipe. The hole on the air distributor should be 10mm or less in diameter for efficient air water mixture. The outlet from the delivery pipe must not be connected to the long conveyance pipes since this will cause hammering when the water is ejected out due to large air pockets formed during the horizontal travel of the air water mixture in the pipe. The Compressor Pumps are selected as a last alternative when other types of pumps are not suitable due to very high depth. These pumps deliver water intermittently and continuous flow of water like other pumps is not expected since water is mixed with air.
