Subject matter of the invention is a cutting ring for solids-loaded fluid of a pump, comprising a cutting ring base body forming an opening for cooperation with a cutting head, which cutting ring can be stationarily connected to the pump in an axial extension of an impeller of the pump, wherein



a plurality of cutting teeth comprising respectively at least outer cutting edges oriented away from the impeller in the direction of a suction side of the pump are provided at the cutting ring base body around the opening, wherein the cutting teeth extend axially away from the cutting ring base body outwardly at least in the direction of the suction side, and
at least in the outwardly extending cutting teeth a respective radially outwardly extending material recess is formed, and/or
a radially outwardly extending axial depression is formed in the cutting ring base body in a valley between two at least outwardly extending cutting teeth.
