A cutting blade assembly operably coupleable to a fluid pump , the cutting blade assembly comprising: a cutting plate having an axial face and an opening defining a radial face that is skewed relative to the axial face ; a first series of cutting slots formed in the cutting plate and circumferentially spaced about the opening , each of the first series of cutting slots intersecting the axial face and the radial face , and defines a respective first axial cutting edge at the intersection of each of the first series of cutting slots and the axial face , wherein each of the first series of cutting slots establishes fluid communication with the opening in the cutting plate ; a second series of cutting slots formed in the cutting plate and circumferentially spaced between adjacent ones of the first series of cutting slots , each of the second series of cutting slots intersecting the axial face to define a respective second axial cutting edge at the intersection of each of the second series of cutting slots and the axial face ; and a cutting hub positioned in the opening and having a cutting arm adjacent to the axial face , wherein the cutting arm defines an arcuate front surface and a leading edge; wherein when the cutting plate and the cutting hub undergo relative rotation, the leading edge of the cutting arm passes adjacent to the first axial cutting edges of the first series of cutting slots and the second axial cutting edges of the second series of cutting slots so that the relative rotation of the cutting plate and the cutting hub defines a scissor-type cutting action between the leading edge and both the first axial cutting edges and the second axial cutting edges . a cutting plate having an axial face and an opening defining a radial face that is skewed relative to the axial face ; a first series of cutting slots formed in the cutting plate and circumferentially spaced about the opening , each of the first series of cutting slots intersecting the axial face and the radial face , and defines a respective first axial cutting edge at the intersection of each of the first series of cutting slots and the axial face , wherein each of the first series of cutting slots establishes fluid communication with the opening in the cutting plate ; a second series of cutting slots formed in the cutting plate and circumferentially spaced between adjacent ones of the first series of cutting slots , each of the second series of cutting slots intersecting the axial face to define a respective second axial cutting edge at the intersection of each of the second series of cutting slots and the axial face ; and a cutting hub positioned in the opening and having a cutting arm adjacent to the axial face , wherein the cutting arm defines an arcuate front surface and a leading edge; wherein when the cutting plate and the cutting hub undergo relative rotation, the leading edge of the cutting arm passes adjacent to the first axial cutting edges of the first series of cutting slots and the second axial cutting edges of the second series of cutting slots so that the relative rotation of the cutting plate and the cutting hub defines a scissor-type cutting action between the leading edge and both the first axial cutting edges and the second axial cutting edges . <EOS>
