ABSTRACT:
A centrifugal pump for shear sensitive fluids includes a pump housing defining an interior volume. An impeller comprising at least two vanes is rotatably mounted in the housing. The impeller vanes, which preferably are airfoil-shaped, are spaced from the interior housing of the pump whereby to leave a gap between the vanes and the pump housing so as to permit a portion of the fluid in the spacing to flow smoothly over the top contour of the impeller vanes.
