Abstract: A pneumatic pumping system for conveying particulate materials in system piping. The pumping system includes a linear accelerator apparatus having an inductor assembly with an inductor nozzle cooperating with a venturii casing in which the venturii casing has a shroud portion encompassing a discharge orifice of the inductor nozzle to form an annular passage through which pressurized conveying gas is directed, the conveying gas mixing with a material flow through the nozzle, the material flow through the nozzle being facilitated by a gas stream directed along an inside wall of the inductor nozzle, the linear accelerator apparatus being combined with other apparatus including a material pumping unit or a pressurized pod system, or, incorporated in-line in the system piping as a flow booster.
