A water jet pump operates by using the kinetic energy of a high-pressure water stream to create a vacuum. The pump consists of a nozzle, a venturi tube, and a suction chamber.
When pressurized water is forced through the nozzle, it creates a high-velocity stream of water. This stream passes through the venturi tube, which is a constricted section of the pump that causes the water to speed up and decrease in pressure. As the water flows through the venturi tube, it creates a low-pressure area in the suction chamber connected to the tube.
This low-pressure area in the suction chamber acts as a vacuum, drawing in air or other gases from the surrounding environment. The suction chamber can be connected to a container or system that needs to be evacuated, allowing the pump to remove air or gases from the container.
Overall, the water jet pump uses the energy of the pressurized water stream to create a vacuum by generating a low-pressure area in the suction chamber through the venturi effect.

Operation of a Water Jet Pump in Creating a Vacuum
A water jet pump is a device that uses the kinetic energy of a high-velocity water jet to create a vacuum. It consists of three main components:
- Converging nozzle: This is where the water is forced through to create a high-velocity jet.
- Mixing chamber: This is where the water jet mixes with the fluid being evacuated.
- Diverging diffuser: This is where the air and water mixture decelerates and separates.
How it Works:
1. Water is pumped into the converging nozzle: The water is driven through the nozzle at high pressure, creating a high-velocity jet.
2. The jet creates a Venturi effect: The high-velocity jet creates a region of low pressure around it, according to the Venturi effect. This low-pressure region draws in the air from the fluid being evacuated.
3. Mixing and acceleration: The air is entrained into the water jet and accelerated by its momentum. The mixture of air and water becomes less dense and travels faster.
4. Deceleration and separation in the diffuser: The mixture enters the diverging diffuser, which gradually slows down the flow. As the fluid decelerates, the air and water separate due to their density difference.
5. Evacuation of air: The air, now at a lower pressure, is drawn out of the evacuated fluid. The vacuum is created by the removal of air from the fluid.
Advantages of Water Jet Pumps:
- Can create high vacuum levels (over 99% vacuum)
- No moving parts, resulting in low maintenance
- Silent operation
- Can handle large volumes of fluid
- Suitable for applications where contamination is a concern, as the only fluid used is water
Applications:
Water jet pumps are used in various applications, including:
- Vacuum degassing of liquids
- Tank drainage
- Acid extraction
- Vacuum filtration
- Air sampling
