Eductors, Syphons, Scrubbers, Desuperheaters, Compressors, Steam Jet Heaters and Tank Mixers
Providing a practical alternative to more complicated and expensive methods, jet eductors offer simple, more cost-effective
ways to pump, mix or heat a wide range of liquids and gases used in the process industry. Jet pumps can operate
with a wide variety of motive liquids and gases. If you recognize any of the following, you can probably use
a jet pump.
Jet pumps have a myriad of uses. Jet pumps not only pump liquids, they can also heat, mix and blend either in-line
or in-tank. Jet pumps can evacuate gases, create a vacuum, boost suction pressures, mix granular solids with
liquids and move granular solids with compressed air. In fact, you will be surprised at what a jet pump can
do to solve your problem.
The purpose of this section and its associated pages is to identify the many uses for jet pumps, to identify pumps
for specific processing operations and perhaps recognize new ways to use jet pumps to reduce costs and optimize
your plant’s efficiency. We invite you to explore the possibilities of jet pump use in your operation. You
might be surprised at the many ways jet pumps can help improve your company’s profitability!
While jet eductors may differ in appearance, basic operation is the same. Jet pumps, also known as eductors, operate
on the principles of fluid dynamics. An operating fluid media, which is referred to as the MOTIVE, placed under
pressure enters the inlet and is forced through the nozzle where it is converted into a high-velocity stream.
This high-velocity stream decreases the pressure in the suction chamber, creating a partial vacuum that draws
the suction material into the chamber where it is entrained by the motive media. Once the SUCTION stream is
drawn in, shear between motive media and the transported material causes both media to be intermixed and pumped
out the DISCHARGE outlet, dispelled at a pressure greater than that of the SUCTION stream but lower than that
of the MOTIVE. This basic principle of fluid dynamics is what makes jet pumps work.
