EDUCTORS FOR TANK
BLENDING OF OILS.
For the tank blending of oils,
the arrangement shown has
proved highly satisfactory.
In this particular installation
five 8” Fig. 258 Eductors are
used in a 100’ tank. Initially,
the eductors are used to fill
the tank during which time
they provide continuous
agitation. After the tank is
filled, the oil is drawn off and
recirculated by means of the
same pumps. Oil from the
top of the tank issues
through the eductor nozzle
and entrains oil from the
bottom of the tank. The two
are mixed in the throat of the
eductor and are discharged
with sufficient force to
maintain constant agitation
and further blending in the
tank.

Fig. 30. FIG. 258 EDUCTOR IN BATCH MIXING APPLICATION.
This illustrates the batch mixing of two or more liquids with an S&K Fig. 258 Eductor.
The pressure liquid, taken from the top of the tank is passed through a pump to the
eductor. The jet action of this fluid entrains the liquid at the bottom of the tank and
proper mixing results.

EDUCTOR USED IN
MIXING DRY POWDER.
Mixing dry powder and a
liquid prior to discharge
into a tank is
accomplished through the
use of a Fig. 235 Eductor
as shown here.
Pressure liquid enters the
eductor, entrains the
powder, mixes the two in
the venturi of the eductor
and discharges the
mixture into a receptacle.
The streamline eductor
design provides maximum
efficiency in this operation.

TYPICAL
PROPORTIONING
SYSTEM.
This shows a typical
proportioning system
using a Fig. 242 Eductor.
Rate of flow is measured
by a Rotameter and is
controlled by a valve in the
line. A valve in the
pressure line and orifice of
the eductor nozzle control
the flow of the pressure
liquid. Fluids are
thoroughly mixed in the
desired proportions and
are then discharged.
