Cutter Pumps
Product Information
The cutter pump was created in order to address the urgent need of reducing clogging due to ragging. With the increased use of ‘flushable’ materials and extraneous cleaning products, the issue of clogging—leading to downtime, pump destruction, and pipe damage, has increased markedly. Useful in municipal, agricultural, and other markets, the cutters unique stationary and rotating blade design allows material to pass through the impeller that would tend to clog a non-cutter pump. The cutter costs a minimal amount of product efficiency and is specially designed to break up clogs and prevent ragging. The cutter is adjustable and made from special hardened metal to last in difficult service. The cutter impeller can be retrofitted on existing pumps, and won’t change the external pump dimensions.
- Minimal Energy Consumption
- Designed to break up clogs/ Prevent Ragging
- Hardened cutter material
- Adjustable
Features and Benefits |
Applications |
| Cutters are hardened for long life | Minimal increase to cost of operation |
| Cutters are shaped to minimize flow restrictions | Labor savings by reducing clean out events |
| Cutters in new pumps are covered by our Industry leading, Two Year Warranty | Pump Station efficiency improvement by reducing down time and periods of low flow |
Chopper Pumps
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.
