Embodiments of the invention provide a cutting blade assembly operably coupleable to a fluid pump. The cutting blade assembly comprises a cutting plate and a cutting hub. The cutting plate may have a front axial surface, an opening, and a plurality of cutting features. Each of the plurality of cutting features may define a pair of cutting edges. The cutting hub may be disposed at least partially within the opening of the cutting plate and may have a cutting arm and fin adjacent to the front axial surface. The cutting arm may define an arcuate front surface having a leading edge. When the cutting plate and the cutting hub are rotated relative to each other, the leading edge of the cutting arm may pass adjacent to the plurality of cutting features so that the relative rotation of the cutting plate and the cutting hub defines a cutting action between the cutting arm and each cutting feature.

A cutting blade assembly including a cutting plate, a plurality of cutting slots formed in the cutting plate, and a cutting hub. The cutting plate includes an axial face and a central opening. The plurality of cutting slots are circumferentially spaced about the central opening. Each of the plurality of cutting slots intersects the axial face and defines a respective axial cutting edge at an intersection of each of plurality of cutting slots and the axial face. Each of the plurality of cutting slots defines a base surface that is nonparallel to the axial face. The cutting hub is positioned in the central opening and has a cutting arm adjacent to the axial face.
