The blade within the fluid intake portion has a flat and/or concave pressure face, and a root that is helically shaped to 00 the longitudinal axis according to a logarithmic, exponential, power or other sequencing such that the tangent to the blade approaches perpendicular alignment to the axis at a first end of fluid intake portion and approaches parallel alignment to the axis at a second end of O fluid intake portion. The fluid outlet is longitudinally offset from the fluid intake. Alternatively, a second substantially helically shaped C portion has an opposite chirality to the first substantially helically shaped portion.
