A rotary pump with hydrodynamically suspended impeller

A is suitable for the continuous for extracting blood's pump device (1,33,200). The specific form, the pump (1,200) is a centrifugal pump, an impeller (100,204) are sealed in pump cavity (2,201), and liquid (105) is rotating according pushes the pump cavity (106,203) is electromagnetic devices along with the impeller, impeller is hydrodynamics the suspension. Hydrodynamics suspension connected with the impeller of can (100,204) by a motor, deformation for example (102,223) and back flange (103,224) with inclined surface blades at the bottom and top edge (221,222) front end (8).
