A single or multi-stage centrifugal pump or mixer duplex shear force rotor. The rotor is circular and consists of two non-parallel shrouds with inner, opposing faces. The driven shroud contains a center opening. The rotor has an open, unobstructed entrance section with no raised ribs and includes a protrusion designed to force-feed the discharge section in a smooth laminar flow pattern. The discharge section incorporates a series of raised ribs. The raised ribs begin at the peripheral edge of the drive and driven shrouds and extend in a direction towards the center of the drive and driven shroud and terminate approximately 50% of the distance from the periphery and the center of the rotor. Cast-in-place spacers space the drive and driven shrouds. Alternatively, the rotor can include no raised ribs. In addition, the raised ribs can have a cross-section that includes a tapered trailing edge to reduce wear. The rotor can also be used without inclusion of the raised ribs. Alternatively, neither the drive or driven shroud are perpendicular to the axis of rotation.
