<p>A cutter assembly and high volume submersible shredder pump. These are for reducing the size of solids within a liquid which is to be pumped by chopping, grinding, shredding or cutting. An improvement over prior designs employs cutting lobes having a grooved surface which mate with corresponding grooves of a circular plate cutter. As a result, many more cutting surfaces are provided which more effectively and quickly shred the solid materials within the liquid to be expelled.</p> |
