Eductors
Water Jet Eductors
Water Jet Eductors utilize a high pressure fluid to handle a low
pressure fluid and discharge the mixture against an
intermediate pressure using the venturi principle.
Ejectors of this type are used throughout industry
for pumping and mixing operations.

Steam Jet Syphons
Steam jet syphons are similar to the Water jet eductor however, they use
steam as the motive force to pump, mix liquids and
handle solids. In operation, steam under pressure
discharges at high velocity through a nozzle and
entrains the suction liquid or slurry. Both the
Water Jet eductor and the Steam jet syphon can be
used for the handling of corrosive or abrasive
liquids and solids. Their design simplicity, absence
of moving parts, and because they can be made from
any machineable material, make them ideal for a
multitude of applications.
Solids Handling Eductors
Solids Handling Eductors employ motive air or liquid
under pressure through a nozzle in the eductor that
produces a high velocity jet to entrain and
transport dry solids or slurries. The two types of
solids handling eductors are as follows:
-
Pneumatic conveying eductors
for handling dry
solids – These employ motive air from a
compressed air source or a blower to entrain and
transport solids
-
Eductors using liquid in handling
dry solids –
These use liquid under pressure which issues
through a nozzle in the eductor and produces a
high velocity jet to transport granular solids
or slurries
