A directed multiport jetting nozzle in an eductor having a focal point of the motive fluid inside the throat of a venturi-diffuser body of the present eductor provides an efficient pump and mixer providing substantial surface contact area between the motive flow and the bulk material for movement through the outlet of the eductor. The result of this design provides a homogeneous mixture of the motive fluid and the bulk material which may be hydrating or wetting, or the creation of a slurry.

1. An eductor comprising: a cylindrical body having a longitudinal bore therethrough and a perpendicular extension having a bore therethrough intersecting the cylindrical body permitting a flow of bulk materials into a low-pressure vestibular mixing chamber portion of the eductor;said low-pressure vestibular mixing chamber portion of the eductor formed between an outlet face of a multiport jetting nozzle inserted in a first end of the cylindrical body, the intersection of the perpendicular extension, and an inlet lip of a venturi-diffuser inserted in a second end of the cylindrical body; and,said multiport jetting nozzle providing a plurality of ports for directing a fluid flow from a first inlet of the cylindrical body toward the inlet lip of the venturi-diffuser having a venturi-diffuser throat narrowing to provide turbulent flow and enlarging at an outlet of the venturi-diffuser;wherein the fluid flow traversing the vestibular mixing chamber portion from the multiport jetting nozzle carries and mixes with the bulk material from the perpendicular extension; andthe plurality of ports are angled for converging the fluid flow at a point within the venturi-diffuser. 2. The eductor of claim 1 wherein the plurality of ports comprises three or more directed ports angled for converging the fluid flow at the point within the venturi-diffuser. 3. The eductor of claim 1 wherein the plurality of ports comprises at least five directed ports angled for converging the fluid flow at the point within the venturi-diffuser. 4. A method of fluid mixing comprising: supplying a fluidal bulk material to a perpendicular inlet of an eductor; and,supplying a fluid motive flow through an inlet of the eductor to a multiported jetting nozzle having a plurality of ports angled for directing the fluid motive flow across a vestibular section of the eductor and into a centralized portion of a venturi-diffuser for movement down the venturi-diffuser for homogeneously mixing the fluidal bulk material with the fluid motive flow;wherein the vestibular section of the eductor is formed between an outlet face of the multiported jetting nozzle, an intersection of the perpendicular inlet with a body of the eductor, and an inlet of the venturi-diffuser; andat least a portion of homogenously mixing the fluidal bulk material with the fluid motive flow is within the vestibular section of the eductor. 5. The method of claim 4 wherein the fluidal bulk material comprises a slurry. 6. A method of fluid mixing of a variety of fluidal bulk materials with varying physical characteristics comprising: supplying a first fluidal bulk material to a perpendicular inlet of an eductor;supplying a motive fluid flow through an inlet of the eductor to a multiported nozzle directing the motive fluid flow across a vestibular section of the eductor, the multiported nozzle having a plurality of ports angled for converging the motive fluid flow in a centralized portion of a venturi-diffuser for movement down the venturi-diffuser for homogeneously mixing the fluidal bulk material with the motive fluid flow until the fluidal bulk material has been completely mixed;adding a second fluidal bulk material to a secondary inlet on the perpendicular inlet of an eductor; and,varying a rate of passage of the second fluidal bulk material to the vestibular section of the eductor for mixing;wherein the vestibular section of the eductor is formed between an outlet face of the multiported jetting nozzle, an intersection of the perpendicular inlet with a body of the eductor, and an inlet of the venturi-diffuser; andat least a portion of homogenously mixing the fluidal bulk material with the motive fluid flow is within the vestibular section of the eductor. 7. The method of claim 6 further comprising the additional step of varying the motive fluid flow to the multiported nozzle to correspond to physical characteristics of the second fluidal bulk material. 8. The method of claim 6 wherein the first fluidal bulk material comprises a slurry. 9. The method of claim 6 wherein the second fluidal bulk material comprises a slurry.
