DEFINITION

Classification: 417/176

(under subclass 151) Apparatus having a plurality of motive fluid nozzles, the motive fluid from each acting to entrain pumped fluid, the combined motive and pumped fluid from each entrainment traveling in a separate downstream conduit or combining tube, the entrainments being in parallel with one another; i.e., each motive fluid stream is separate from the others and acts to entrain separate flows of pump fluid.

(1) Note. The pumped fluid may originate in a common pipe or conduit and the outputs from the downstream conduits may combine into a single flow.

SEE OR SEARCH THIS CLASS, SUBCLASS:

163, for the successive introduction of motive fluid to a single pumped fluid stream.

174, for a single motive fluid stream which successively entrains pumped fluid.
