Cornell’s Chopper Pump is ideally suited for chopping Solids. The standard casing, made of ASTM A536 grade 65-45-12 ductile iron, stands up to robust applications. Everything about the pump is built to tackle hard jobs, from the replaceable cutter bar made of T1 tool steel heat treated to a minimum of 60 Rockwell C hardness, to the heat treated cast steel impeller. The Cornell Chopper pump series is a heavy-duty performer.
