Innovation

Many Cornell innovations have evolved from their commitment to the municipal market and our ongoing effort to work with the people in this industry to solve their pumping problems

External Hydraulic Balance Line

Cornell developed the external hydraulic balance line in response to irrigation system problems in California brought on by earthquakes in the mid-50's. This balance line assists in moving sand and silt from the sealing chamber to the low pressure area at the pump suction. This reduces erosion of wetted parts and also reduces the axial forces acting on the impeller, shaft and bearings.

Double Volute

Cornell introduced the double volute hydraulic balancing concept to the end suction pump in the early 50's. The double volute balances radial forces with the pump to reduce shaft flexure and fatigue. Cornell's double volute system eliminates shaft breakage and extends the life of packing and mechanical seals, wear rings and bearings, while maintaining high hydraulic efficiencies and clog free operation.

Efficiency

In addition to a reliable pumping system, today's municipal operations must also be efficient and economical. As energy costs rise, conservation and efficiency of operation are becoming key issues for operators as they strive to minimize expenses associated with energy consumption. Cornell pumps have superb hydraulic operating efficiencies and coupled with high efficiency motors cost less to run and operate.
