Zusammenfassung:	A grinder pump with a self aligning cutter assembly, the grinder pump having an inlet port, a drive shaft and a cutter assembly, the cutter assembly comprising a rotary cutter and a stationary, annular cutter. The rotary cutter is supported for rotation by the drive shaft, and the annular cutter is supported in the inlet port. The rotary cutter has a pair of primary knife members with knife edges, and the annular cutter is supported in the inlet port, the annular cutter having a central bore in which a plurality of internal cutting edges are formed. The rotary cutter is supported in the central bore so its primary knife members are rotated in operational cutting engagement with the internal cutting edges by the drive shaft. The annular cutter is provided a limited range of radial movement and is positioned within the range of movement by the rotary cutter.
