Abstract:
A single stage turbine impeller pump assembly, including in combination:a rotatable shaft;inboard and outboard casing members coupled together, each having cavity channels therein and each having a surface having an annular recess therein and an axial opening there through which permits said shaft to rotate therein;inboard and outboard liner members structurally arranged to be received by the respective annular recesses in said casing members, with each of said liner members being fixed to a respective one of said casing members;an impeller member positioned between said liner members and fixed for rotation with said shaft; andwherein said inboard and said outboard liner members each have at least two flow channels which are uniformly distributed therein and include an inlet and a discharge positioned at 180.degree. or less from each other and which are structurally arranged to cooperate with said cavity channels in said inboard and said outboard casing members to provide equal and opposite pressures on said impeller member to maintain said impeller in alignment with respect to said liner members.
