CORNELL PUMP COMPANY
Mission Statement To exceed our customers and shareholders expectations, by designing,manufacturing, and marketing premium quality centrifugal pumps.
Our PolicyWe will provide products and services which meet applicable requirementsand we will strive for continuous improvement.
Quality. Dependability. Innovation. Ruggedness. Reliability. These are all words that embody the philosophy of Cornell Pump Companys team.As we enter the 21st century, Cornell is positioned to serve industriesdedicated to improving the quality of life for a growing world population.
As the population grows and world resources become scarce, we at Cornellrealize that it is essential to provide the efficient pumping solutionsnecessary to sustain and improve the global standard of living. We arefocused on producing end suction centrifugal pumps pumps thatimprove the state-of-the-art of waste handling by helping to save water,conserve energy and improve our environment. We are proud of ourongoing investment in research and development, manufacturing testfacilities and quality assurance. We believe in our products and services,and back them with an industry-leading two-year warranty.
InnovationMany Cornell innovations have evolved from our commitment to themunicipal market and our ongoing effort to work with the people in thisindustry to solve their pumping problems.
External Hydraulic Balance LineWe developed the external hydraulic balance line in response to irrigationsystem problems in California caused by earthquakes in the mid-50s.The balance line assists in moving sand and silt from the sealing chamberto the low pressure area at the pump suction. This reduces erosion ofwetted parts and minimizes the axial forces acting on the impeller, shaftand bearings.
Quality MaterialsThe highest standards are applied in the selection of materials for
Cornell products. Cornells pumps are constructed of cast ironand fitted with bronze components. Standard features include
fully machined bronze impellers, heavy duty shaftswith replaceable shaft sleeves, and peripheral wear
rings. Other materials of construction areavailable as an option to handle highpressure or abrasive applications.

Energy RecoveryMany industrial operations are able to harness the potential hydraulicenergy sources required to produce electric power as a revenue source or as a means reduce overall energy demands.
The key to our system is the recovery of excess head from a river, stream,or pipeline to drive a Cornell turbine. The turbine may be used to drive a pump, a generator or other power requiring device.
With power production available from 1KW to 300 KW, Cornells range of high efficiency turbines cangenerate enough power to pay forthemselves in a very short time.
Whether you require a single unit orparallel, Cornell engineers and salespersonnel can provide specialtyapplication assistance.
CUSTOMER TRAININGAt Cornell we believe a well-informed customer is our best customer. Cornell offersa wide range of trainingopportunities and materials to aid customers in the pumpselection process, including ourCentrific software.The Centrific selection programwill help you select the correctCornell pump for a given set of operating conditions. Theprogram also includes energyusage and efficiency comparisons.Cornells catalog includescomplete performance data,dimensional information, seal options and selectionguidelines for the entire clear-liquid and solid-handlingproduct groups. The catalog isdivided into easy-to-usesections and includes acomplete index.

NON-CLOG IMPELLERSCornell offers three uniqueimpeller designs for liquidwastewater applications.Cornells Delta style impeller isexcellent for handling debris,rags, and extremely heavysludge where there is a low tomedium head requirement.The two- and three-portenclosed impellers are designedto handle large solids and haveexcellent efficiencies. Thebladed, semi-open impeller hasa cutting action which allows itto handle difficult slurries at highheads.
Cornells latest innovations for the municipal market have been centeredaround the development of high head non-clog wastewater pumps for lift stations and mixed flow non-clog pumps for process.
With the introduction of our M series of bladed, semi-open impellerpumps, Cornell engineers are working with our customers to address theever increasing number of environmental regulations and concerns aboutwastewater processing and disposal.
Proven PerformanceCornells non-clog wastewater pumps have been used successfully in avariety of agricultural, industrial and municipal wastewater pumpingapplications. Our non-clog pumps excel not only in typical sewage liftstation applications, but also in waste process applications requiring highpressures or high flows.
These pumps are designed specifically to handle abrasive solids, stringymaterials and other matter, efficiently, in tough wastewater applicationsand to provide a long life of service. A variety of impellers are available tomeet the toughest wastewater application needs imaginable.
We, at Cornell, have incorporated many unique and innovative designfeatures into our non-clog wastewater pumps, while at the same timemaintaining our position in the industry as the leader of heavy-duty,low maintenance pumps.

WA T E RCycloseal & Run-Dry FeatureCornells patented (# 5489187) Cycloseal design was developedspecifically for the municipal wastewater market to handle stringy andabrasive pumpage. This sealing system requires no flushing therefore, it is ideal for remote locations where fresh water is not readily available. Avariety of seal materials are offered to handle those difficult applications.Cornells design, with its unique deflector vanes, works with the impeller
back vanes to create a cyclo-action. This action removes
solids and abrasive materials inthe seal area while purging air
and gas pockets, which extendsseal life and eliminates any needfor venting.
Cornells Run-Dry systemconsists of an auxiliary glandwhich provides containment foran application-specific lubricant.This lubricant prevents dry
running of the seal faces whilepriming, re-priming and in standby
Double VoluteCornell introduced the double volute hydraulic balancing concept to the end suction pump in the early 50s. The double volute systemeffectively balances radial forces within the pump, around the impeller, toreduce shaft flexure and fatigue. This eliminates shaft breakage andextends the life of packing and mechanical seals, wear rings and bearings,while maintaining high hydraulic efficiencies and clog free operation.
