MULTI-CHANNEL REGENERATIVE PUMP

摘要

A turbine impeller pump assembly includes a rotating shaft and inboard and outboard casing members coupled together with each having cavity channels, and an annular recess, and an axial opening to receive the rotating shaft. Inboard and outboard liner members are structurally arranged to be received by the annular recesses in the casing members and an impeller member is positioned between the liner members and keyed for rotation with the shaft. The inboard and outboard liner members each have at least two flow channels structurally arranged to cooperate with the cavity channels to provide equal and opposite pressures on the impeller to maintain the impeller in alignment with respect to the liner members.
