ABSTRACT:
A grinder pump cutter assembly having a pair of cutting blades mounted on the cutter disk which extend at a hook angle to substantially the center of the disk. The blade is multi-surfaced, with the surfaces thereof being angled toward the periphery of the disk to break up centralized matter and disperse it into cutting engagement between the disk and cutter ring. Both the disk and cutter ring are also characterized by bores passing through juxtaposed circumferences thereof. The bores each have a hook angle associated therewith to define the sharpness of the cutting edges and to further provide a turbulence of self-purging action within the bores.
