A turbine pump that permits an impeller to stay compliant with a raceway by the use of a preloaded floating raceway that operates by utilizing fluid floating on both side of the raceway within the pump. Exemplary embodiments of the pump include a mounting frame that is adapted to engage the pump to a drive source; an end frame that is adapted to attach to the mounting frame and includes an inlet section and an outlet section that facilitate fluid flow entering and exiting the pump; a motor shaft enclosed within the mounting frame; a floating raceway that is situated within the end frame and positioned around the distal end of the motor shaft, and includes an inlet passage, an outlet passage and a bypass hole fixed relative to the position of the inlet passage and the outlet passage; a spring located at the top of the floating raceway and at least partially contained within a corresponding cavity located in the end frame that is preloaded to help maintain a desired clearance between the floating raceway and the impeller; and an impeller secured to an distal end of the motor shaft.
