  • Patent number: 11365738
    Abstract: A reversible grinder pump with cutter plate and cutter blade, wherein the cutter plate is attached to an inlet of the reversible grinder pump and is located adjacent to the cutter blade, wherein the cutter plate includes pairs of angled openings, wherein each of the pair of angled openings extends through the cutter plate and has a shape which is a mirror image of the other angled opening of the pair of angled openings, when viewed from above a surface of the cutter plate. The cutter blade of the reversible grinder pump contains a pair of triangular cross section, prism-shaped cutting edges, which are congruent to each other and reflective, extending in opposite directions from each other.

  • Patent number: 9352327
    Abstract: A grinder pump basin system is provided which includes a basin; a cover plate; a bracket secured to the cover plate; and a grinder pump with cutter plate with openings and a cutter blade secured to the bracket above a bottom surface of the basin. The openings in the cutter plate have an unique shape which assists in the cutting of material which flows through an inlet of a grinder pump. The shape of the cutter blade cooperates with the openings in the cutter plate such that solids are forced between these respective components and thereby are efficiently cut into small pieces for passing through the openings and for discharge from the grinder pump basin system.
