Water Jet Eductors Bulletin 2M
Fig. 264 and Fig. 266 Water Jet Eductors
S&K Fig. 264 and Fig. 266 Water Jet Eductors are designed for
liquid pumping and mixing operations and for the handling of
some solids where requirements do not necessitate capacities
greater than those obtained with sizes up to and including 6”.
They are considered the standard eductors within this size
range. Typical applications begin on page 12.
In operation, pressure liquid enters the eductor through the
pressure nozzle and produces a high velocity jet. This jet action
creates a vacuum in the line which causes the suction liquid to
flow up into the body of the eductor where it is entrained by the

pressure liquid. Both liquids are thoroughly mixed in the throat
of the eductor and are discharged against back pressure. The
streamlined body with no pockets permits the pressure liquid to
move straight through the eductor and reduces the possibility of
solids in the suction material collecting and clogging. In
addition, pressure drop in the suction chamber is held to a
minimum.

These eductors are similar to Fig. 264
Eductors except that they have flanged
connections and removable throat
bushings along with removable nozzles.
They are supplied in cast iron, bronze-
mounted in 4” and 6” sizes. Other
materials can be supplied on special order.

Eductors of this type have streamlined bodies with
threaded pipe connections. They are made in sizes
ranging from 1/2” to 3” and are stocked in these sizes
in ductile iron and bronze and Fig. 316 stainless steel.
They are stocked in sizes from 1/2”, 2”, and 3” in PVC.
Other materials are available on order.
