CHOPPERCORNELL PUMP COMPANYEFFICIENT BY DESIGNEFFICIENT BY DESIGNEFFICIENT BY DESIGNCHOPPER PUMPSThE CORNELL ChOPPER PUMPChOPPER BENEFITS TYPICAL APPLICATIONSThe Cornell’s Chopper pump is ideally suited for chopping solids. The standard casing for this pump is ASTM A536 grade 65-45-12 ductile iron. The replaceable cutter bar is T1 tool steel heat treated to a minimum 60 Rockwell C hardness. Standard construction includes a heat treated cast steel impeller. Back-to-back angular contact ball thrust bearings and single ball radial bearings make for smooth operation. Each pump is fitted with a John Crane type 2, tungsten carbide single mechanical seal. The Cornell chopper pump is a heavy-duty performer.Eliminates the vast majority of clogging problems:• Chops solids up to 2 inches• No seal flush system necessary• Heavy duty construction• A variety of Mounting Configurations• Efficiency to 65%• TDH to 250 feet• Operating speeds to 1800 RPM• Lift Stations• Septage Receiving• Sludge Transfer and Recirculation• Digestor Scum Blankets• Clarifier ScumCHOPPER PUMPSThE CORNELL ADVANTAGEOne of the greatest advantages of the Cornell chopper pumps is that no water flush system is necessary, eliminating the oily mess created by such systems. Our pumps are ruggedly built and require minimal maintenance. A variety of mounting configurations are available to fit your application needs.Cornell ChOPPER Pump Sizes:6” x 4” or 8” x 6”Cornell ChOPPER Pump Capacities:0 GPM to 2,000 GPMCornell ChOPPER Pump heads:70 Feet to 250 FeetStandard construction of Cornell Chopper pumps includes a ductile iron case, replaceable cutter bars of T1 tool steel (heat treated to a minimum 60 Rockwell C hardness), a heat treated cast alloy steel impeller (min. 60 Rockwell hardness) and stainless steel shaft sleeve, plus a John Crane type 2 tungsten carbide mechanical seal.Cornell Chopper Pumps are exceptionally efficient at higher flow rates with discharge heads of up to 140’ @ 1800 RPM.4NC6NCREfficient by Design10/31/061280604020CAPACITY U.S. GALLONS PER MINUTECUBIC METERS PER MINUTETOTAL DYNAMIC HEADFEETMETERS320 64080 16040MODEL2. 6NC1 .4NC500 20002500501002001000100FAMILY MAP - CHOPPER PUMPSNEW PAGECornell Pump Company Portland, OregonFAM-CHOPP150250300Cornell Pump Company16261 SE 130th AveClackamas, OR 97015P: (503) 653-0330F: (503) 653-0338Cycloseal®, and Redi-Prime® are Registered Trademarks of Cornell Pump Company.

Why take a submersible motor that was designed to run submerged 100% of the time and modify it to run in air 99% (or most of the time) and submerged 1% of the time (in case of a flood)? This seems backwards. The correct approach is to take a TEFC motor that is designed to run in air 100% of the time and adapt it to run submerged 1% of the time (in case of a flood).Immersible Motor Basic design:The basic design of the immersible pump/motor incorporates a premium efficient, inverter duty, P-Base or C-Face TEBC motor (totally enclosed, blower cooled). The motor, as the name implies, is totally enclosed and cooled by a blower on top of the motor. If the motor becomes submerged, the blower motor fan shuts down without affecting the main motor. While the motor is temporarily submerged, the media cools the motor just like a true submersible. A special conduit box is used to prevent water leakage into the motor. The motor is designed to prevent infiltration of water along the shaft and into the motor by utilizing a triple redundant sealing system, including a patented Hydroseal design. The motor-end bell housing incorporates the ‘inverted cup’ principle, which traps an air bubble under the motor as water rises, thus keeping water away from the shaft seal. The shaft is fitted with a hydroseal, which expells water and further reduces the chance of water reaching the shaft seals.The Immersible motor can withstand up to 30 feet of submergence depth for a two-week period. This exceeds the requirements of Immersible motors that is described in the industry standard “Index of Protection” IP67. Competive designs only allow immersion of the motor for a period of time not exceeding 30 minutes at a submergence level of 3 feet. Hardly enough time to deal with any kind of flooding emergencyThe ImmersIble moTor ConCepT:CORNELL PUMP COMPANY // 16261 SE 130th AVE CLACKAMAS, OR2013 © ALL RIGHTS RESERVEDIMMERSIBLECornell pUmp CompAnYFOOD PROCESSCORNELL PUMP COMPANYEFFICIENT BY DESIGNWATER TRANSFERCORNELL PUMP COMPANYHYDRAULIC FRACTURINGEFFICIENT BY DESIGNREDI-PRIME®CORNELL PUMP COMPANYAND VENTURI PRIMEEFFICIENT BY DESIGNMUNICIPALITIESCORNELL PUMP COMPANYEFFICIENT BY DESIGNMININGEFFICIENT BY DESIGNCORNELL PUMP COMPANYEFFICIENT BY DESIGNCUTTER PUMPSEFFICIENT BY DESIGNCORNELL PUMP COMPANYCHOPPERCORNELL PUMP COMPANYEFFICIENT BY DESIGNEFFICIENT BY DESIGNEFFICIENT BY DESIGNEND GUN BOOSTER PUMPSEFFICIENT BY DESIGNFOR CENTER PIVOT IRRIGATIONCORNELL PUMP COMPANYHYDRAULIC SUBSCORNELL PUMP COMPANY• Models Available - 4NNT, 6NNT, 8NNT, etc.• Discharge Sizes Available - 4 to 8 inch• Standard Construction - Cast Iron, Class 30• Optional Construction - 316SS, CD4MCU, Ductile Iron• Permco hydraulic drive• Various adaptor plates available for hydraulic motor ? t• Heavy duty shaft / bearing frame assembly• Heavy duty “wet end” construction• Manufactured in the United States• Premium Hydraulic Effi ciencies, 76 to 80% BEP• 3 inch or larger solid handling capability• Total Dynamic Head: 50 to 360 feet• Capacity: 200 to 7000 GPM• General Agriculture, Industrial and Municipal Applications• Rental Applications• Mining Applications• Flood Control Applications• Construction / Dewatering ApplicationsSTANDARD SPECIFICATIONSFEATURES BENEFITSPERFORMANCE CHARACTERISTICSTYPICAL MARKETSEFFICIENT BY DESIGNMANURECORNELL PUMP COMPANYEFFICIENT BY DESIGNMP SERIESCORNELL PUMP COMPANYEFFICIENT BY DESIGNEFFICIENT BY DESIGNMINING PUMPS DESIGNED FOR COARSE ABRASIvESMX SERIESCORNELL PUMP COMPANyEFFICIENT by DESIGNOIL & GASCORNELL PUMP COMPANYEFFICIENT BY DESIGNSLURRY PUMPSCORNELL PUMP COMPANYEFFICIENT BY DESIGNSTX SERIES SUBMERSIBLEHYDRO TURBINEAGRICULTURAL REFRIGERATIONMUNICIPALMINE DEWATERINGFOOD PROCESSCUTTERCHOPPER EDGETM HYDRAULIC SUBS MANURE MP SERIESMX SERIES OIL & GAS REDI-PRIME SLURRYINDUSTRIALIMMERSIBLEREFRIGERATIONCORNELL PUMP COMPANYEffiCiENt bY dEsigNWATER TRANSFERCORNELLPUMP.COM©2013 CORNELL PUMP COMPANYMARKET AND PRODUCT LINE
