What is the working principle of deep well jet water pump?

A deep well jet water pump operates on the principle of creating a vacuum to lift water from deep underground. It consists of a jet assembly that uses a high-velocity jet of water to create a low-pressure area, allowing groundwater to be drawn into the pump. As water enters the jet assembly, it mixes with the high-velocity jet and is propelled upward through a discharge pipe. This system effectively utilizes the energy from the water flow to lift and deliver water to the surface.
