Jet Pump Principles
The basic concept of a jet pump involves injecting power fluid (pressurized water or oil) down the power fluid flow path at a design rate and pressure. Once the fluid reaches the jet pump, the flow path area is decreased through a sized nozzle, increasing the velocity of the fluid creating a venturi effect. The differential pressure created from the venturi effect draws reservoir fluid into the jet pump. The power fluid and reservoir fluids commingle and the pressure increases as the velocity drops through the flowpath of increased area. The pressure increase is sufficient to lift the commingled fluids to surface.
