Abstract
A cutting assembly and a grinder pump including the cutting assembly are disclosed. The cutting assembly includes a cutting plate that has a plurality of cutting ports with cutting edges that are distributed over a range of radial locations of the plate. The cutting edges of the cutting ports define a series of cutting regions of the cutting blades of a rotary cutter that operate in a shearing action with the cutter plate. The cutting action by the blades of the rotary cutter is distributed over nearly the entire lengths of the cutting edges of the cutting blades, thereby distributing the wear on the cutting blades evenly, and extending cutting assembly life.
