ABSTRACT:
A regenerative turbine pump apparatus which includes a housing having an inlet and an outlet and a generally circular impeller having a circumference and a geometric axis. The impeller is mounted for rotation within the housing about the geometric axis and has first and second generally circular faces. At least the first generally circular face has a plurality of vanes extending from the circumference generally toward the geometric axis. Each of the vanes has generally planar mutually parallel side walls disposed in oblique relationship to a tangent to the impeller proximate to the intersection of the vane and the circumference. Adjacent vanes about the circumference each being separated by a slot extending from the circumference and extending to a substantially rectilinear line, the substantially rectilinear lines collectively define a plurality of steps around the impeller.
