Multiple jet eductor

In a two part multiple jet pump of which a first part consists essentially of a manifold ring which is provided with a pressurized water inlet and a first plurality of radially spaced, forwardly, and convergingly, directed jet nozzles, a second part consists essentially of a tube having a bell end, said second part being provided, proximally to and at a fixed axial distance from the bell end, with a second plurality of radially disposed bosses equal in number to said first plurality, each boss containing a forwardly, and convergingly, directed porthole adapted to snugly receive a corresponding one of said jet nozzles wherein high pressure water passes through said jet nozzles and into said tube whereat said high pressure water entrains a pumped fluid and develops a low pressure, the improvement consisting of assembling the jet pump by forced simple coaxial translation motion of said first part over said bell end of said second part, all of said jet nozzles simultaneously engaging and entering corresponding ones of said portholes with transitory snake-like flexure in an intermediate position and finally penetrating to a "home position" whereat said jet nozzles revert to their original, free of stress or distortion, molded, straight configuration, and securing said first part to said second part proximally in said "home position" by suitable means.
