Water Jet Eductors Bulletin 2M
Fig. 235 Annular Multi-Nozzle Water Jet
Eductor
Fig. 235 Annular Multi-Nozzle Water Jet Eductors are
designed to handle solids and semi-solids. They operate
at highest efficiency in large sizes and at low discharge
heads. Because these eductors have high air handling
capacities, they are particularly well suited for priming
large pumps such as dredging pumps which frequently
encounter air pockets.
Nozzles on the periphery of the throat introduce the
pressure water. The pressure water creates a vacuum
which draws in and entrains the material being handled
and all flow discharges through the discharge connection.
All suction flow is in a straight line through the eductor.
For performance information, see Bulletin 2M
Supplement.

WATER JET EDUCTOR.
These eductors are made to order from any workable
material. Sizes from 1 1/2” to 6” are cast with flanged
suction, discharge and pressure connections, except
2” size which has sil-brazed pressure connection.
Sizes above 6” (to 28” and up) are generally
fabricated.
