EFFICIENT BY DESIGNCUTTER PUMPSEFFICIENT BY DESIGNCORNELL PUMP COMPANYCUTTER PUMPSADDRESSING AN URGENT NEEDFEATURESBENEFITSRETROFIT AND NEW PUMPSRagging and fouling of impellers has plagued wastewater applications for years. With the increased use of ‘flushable’ materials and extraneous cleaning products, the issue of clogging, downtime, and pump damage have increased dramatically.A CUTTER SOLUTION. Cornell created an innovative cutter design, using a stationary and rotating element to reduce masses of solids to a size that will pass through the pump. Most cutter models have efficiencies that are reduced less than 4% from standard Cornell efficiencies for enclosed, solids handling impellers. This minor reduction is offset by a dramatic increase in “up times”. The resulting increase in pump station efficiency can save tens of thousands of dollars per year.• Minimal Energy Consumption• Designed to break up clogs/ Prevent Ragging• Hardened cutter material• Adjustable• Cutters are hardened for long life• Cutters are shaped to minimize flow restrictions• Cutters in new pumps are covered by our Industry leading, Two Year Warranty• Minimal increase to cost of operation• Labor savings by reducing clean out events• Pump Station efficiency improvement by reducing down time and periods of low flowThe cutter rings can be installed in the majority of Cornell solids handling pumps, and in most cases a motor change is not required. New Cornell pumps from 3” to 16” can be furnished with cutters. Cutter additions to new and existing Cornell Pumps do not result in external dimensional changes to the pump, avoiding costly piping changes in the station.NEW PRODUCT ADDITION OR RETROFIT DOES NOT ChANGE ExTERNAL PUMP DIMENSIONS.CUTTER PUMPSTESTIMONIAL—CUTTER IN ACTION SAvES ThOUSANDS OF DOLLARSSince Introduction in July 2011, Cornell has numerous customers excited about how the cutter pumps have changed their maintenance schedules and increased their ability to do standard/regular repairs rather than emergency pulls for ragging, thus saving them tens of thousands of dollars.Following is a testimonial from a Southern California water district and their experience with Cornell’s Cutter pumps. “The water district replaced another manufacturer’s pump with a Cornell 8NHTA cutter pump in February 2012. After the installation of this new pump, the Maintenance Superintendent went to the station to give it a real test by cleaning the wet well. He indicated that this wet well was very dirty, with a large blanket of rags and trash in which he intends to run through this pump for this test, and to confirm that the pump can be used to clean the wet well on a routine basis. He had the Collections Crew stand by with wash water to wash down the wet well as he pumped this debris through the pump. According to his staff, there were even items such as large plastic sports drink bottles that were running though the pump. According to the superintendent, the pump never choked, or made any indication of exertion. After the wet well was fully cleaned, his staff opened a volute inspection port to inspect the pump. It was clean and had no debris whatsoever in the impeller or volute. Needless to say, he was very happy with this progress. So happy they are considering installing new or modifying existing pumps to have at least one cutter pump per station.” ~Cornell SoCal DistributorCornell Pumps Helps Agitate the Liquid Fertilizer Industry –With New Cutter Pump Outperforming ExpectationsSite:Numerous animal farms in the MidwestThe Problem:A leading Midwest company specializing in liquid manure wants to agitate an entire manure lagoon, without tying up personnel and farm equipment that could be put to other uses. The manure needs to be agitated to ensure that the liquid fertilizer has an even mix of nutrients and to keep solids from settling into the bottom of the pond.Traditionally, lagoon agitation has been accomplished through use of a pump and/or propeller driven piece of equipment backed into the lagoon. This has often powered by a tractor. Using this method, only the area around the piece of equipment is agitated, tying up a valuable tractor and a farm hand. With this method, as soon as the agitation equipment is removed from that section of lagoon, the solids again begin to settle. The Solution:The company devised three di? erent sized Agitation Boats. The entire lagoon can be agitated continuously using a hand held remote control to move the boat. Once the lagoon is agitated, a properly ? tted boat can be pulled up to the bank and used as the lead pump for a drag hose system. Engines on the boat power high-pressure guns that force manure down into the lagoon at rates of 4,000 GPM. The liquid fertilizer expelled is much more consistent, with more predictable nutrient levels. Powering this innovation are Cornell Pumps. The Cornell 4514T pump is featured on their smaller boat, while the larger craft use either the 6NHTB pump or the new 6NHTB cutter pump.End Results:The Cornell 6NHTB cutter pump is performing very well on the lagoons—tackling even those applications with plentiful weeds and garbage that would clog a standard enclosed impeller pump. The extra material to pump doesn’t adversely a? ect pump performance—the 6NHTB still pumps with 80 percent e? ciency when pushing the additional solids. A farmer using the boat even purposefully tried to clog the pump to test its e? ciency, and was unable to clog it APPLICATIONSCORNELL PUMP COMPANYREMOTE CONTROLLED AGITATORSCORNELL’S 6NHTB PUMPS EXCEED EXPECTATIONSCornell Pump Company | Clackamas, OR 97015 USA | www.cornellpump.com| P: +1 (503) 653-0330 | F: +1 (503) 653-03382nd DRAFT 02/28/12 : M-A-12-AS-16Another Cutter installation on a manure boat can be seen by scanning this QR code with a smartphone.CUTTER PUMPSChARACTERISTICS & OPTIONS WITh MOST CORNELL CUTTER PUMPSThICKER, SLEEvED ShAFTSEconomical solution to repeated clean out expenses• Replaceable case wear rings• Double volute (many models)• Heavy-walled castings• Replaceable shaft sleeves• Various mounting configurations• High efficiency• High Suction Lift (Redi-Prime® versions)• Two-year warranty• Oversized bearings• Minimum 20,000 hours bearing life• Patented Cycloseal® design• Low cost of repair• Lower operating costCornell’s alloy steel shaft is more than 25 percent larger in diameter than most other competitors.

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.
