Please Explain Me the working of the Lift Pump with Diagram? But I don't want to know about the airlift pump which uses compressed air. I want the other one.

A lift pump is actually an airlift pump which uses compressed air to lift water from underground. Air from the compressor is blown at the lower end of the pipe that transports the water. The air bubbles rises quickly above water due to buoyancy. Due to fluid pressure the water also moves along with the air bubbles and thus reaches the upper end of the transport-pipe.
