Eductors are an effective way to move liquids, gases and solids. Eductors are also known as ejectors, injectors, jet pumps and venturi pumps.

Eductors are widely used in the petrochemical, process, mining and power industries for pumping, mixing and heating. They are popular because they have no moving parts, require very little maintenance and are safe in hazardous locations where electrical pumps may not be the best solution.

Jacoby Tarbox eductors are one of the most efficient eductors on the market. The eductor bodies are more robust than competitor’s products and are fully ANSI rated, the flow paths have been computer designed for optimum efficiency and the eductor profiles are machined smooth for superior performance.

How does an eductor work?

Eductors use the venturi principle to entrain a low pressure fluid with a high pressure fluid and discharge the mixture against an intermediate pressure.

An eductor converts the pressure energy of a fluid (the motive) into velocity. The motive expands through the eductor nozzle to create a vacuum and this entrains the second fluid (the suction). The two fluids mix and repressurise within the eductor to an intermediate pressure as the velocity is converted back into pressure, before discharging through the outlet nozzle.

  • Tank Liquid Agitators

    Tank Liquid Agitators (TLA’s) are a type of eductor designed for mixing liquids within a tank. These units replace mechanical agitators, but have no moving parts.

    Inlet fluid accelerates through the body of the TLA, entraining the tank contents and mixing the two fluids. The TLA multiples the inlet flow, typically by a factor of four to five and discharges the mix with a long plume.

    Tank Liquid Agitators can be used for other purposes such as:

    • Seawater diffusion - discharging water into the sea within regulated limits of temperature and salinity. This has application in desalination plants.
    • Dissolving powdered solids in a liquid within the tank.
    • Heating tank contents with injected steam.

    Standard options include:

    • Sizes from 3/8” to 3” – larger sizes are available
    • Material selection from carbon steel, 316 SS, bronze, PVC, polypropylene and PVDF
    • Connections from male and female NPT thread, socket weld ends, butt weld ends and ANSI flanged
