A jet pump is a device that uses high-velocity jets to move fluids. It operates by converting the kinetic energy of a liquid into pressure energy.
Jet pumps are versatile tools used in various applications, from drawing water from wells to circulating liquids in heating and cooling systems. Unlike traditional pumps, they don’t require a mechanical shaft to connect to a motor; instead, they use a jet of fluid to generate suction.
This design makes them suitable for deep wells or other situations where a long drive shaft would be impractical or too expensive. Jet pumps are also known for their ability to handle a mixture of gases and liquids, which is useful in the oil and gas industry. With their simple design and minimal moving parts, jet pumps are a reliable and low-maintenance solution for fluid transport.

Functionality
These pumps are versatile devices used in various applications. They move liquids, mix fluids, or circulate the flow within a system. Their simple design makes them suitable for many tasks. Let’s explore how these powerful tools operate and the different types they come in.
How Jet Pumps Work
The use of a high-velocity jet of fluid to move another fluid. They consist of three main parts: nozzle, venturi, and diffuser. Here’s the process:
- Fluid enters the pump.
- The nozzle increases the speed of the fluid.
- Speeding fluid creates a vacuum in the venturi.
- The vacuum draws more fluid in.
- The diffuser slows down and increases the pressure of the fluid mix.
- Clean, pressurized fluid exits the pump.
Types Of Jet Pumps
There are two main types of jet pumps:
- Deep Well : These are used for water sources located far below the ground.
- Shallow Well : These are for water sources closer to the surface.
| Jet Pump Type | Typical Use |
|---|---|
| Deep Well | Water extraction from deep sources |
| Shallow Well | Water extraction from shallow sources |
The right type of pump depends on the water source depth and the application needs. Both types ensure efficient water movement for various purposes.

Tips For Maintenance
Keep your pump in top condition with these simple maintenance tips:
- Inspect regularly: Look for signs of wear or damage.
- Clean the ejector: Remove any debris that may block water flow.
- Monitor pressure: Check the pressure gauge for consistent readings.
- Change the oil: If applicable, replace the oil as per the manufacturer’s guidelines.
- Store safely: During non-use, keep the pump in a dry, frost-free environment.
Choosing The Right Jet Pump
Choosing the right Pump is crucial for efficient water movement.
Factors To Consider
Before selecting a pump, several key aspects need consideration:
- Water Source: Identify whether you’re drawing from a well, lake, or river.
- Pump Capacity: Choose one that meets your daily water usage.
- Depth: The depth of your water source impacts the pump type.
- Power Source: Consider available power options like electric or solar.
Sizing And Selection
Correct sizing ensures the jet pump operates efficiently and lasts longer.
Use the following steps and table to help select your pump:
- Determine your water needs in gallons per minute (GPM).
- Measure the depth to water in your source.
- Refer to the manufacturer’s chart for size recommendations.
| Depth to Water (feet) | Recommended Pump Size (HP) |
