Cornell Pump
Submersible and solids-handling centrifugal pumps for abrasive, high-flow, high-head municipal and industrial wastewater service — heavy-walled volute construction up to 20,000 GPM and 450 ft head.
What LibertyCES specifies from Cornell Pump
Cornell Pump Company was founded in 1946 in Portland, OR and has been a division of Roper Industries since 1968. It is best known for "Efficient by Design" centrifugal pump engineering, including submersible and heavy-duty solids-handling lines built for abrasive slurry and wastewater service. LibertyCES reaches Cornell Pump through E-Water Solutions, LLC — its existing Southern California pump distribution partner, which names Cornell Pump directly on its own line card.
Continuously-submerged electric-motor submersible pumps, heavy-duty volute construction for abrasive service, up to 3in solids, published range to 20,000 GPM and 450 ft head.
Heavy-walled volutes for abrasive slurry/wastewater service, 3in-5in solids capacity, published range 80-20,000 GPM and 10-350 ft head.
Cornell Pump — Real Catalog Spec Data
| Product Line | Model | Category | Construction | Solids Capacity | Flow / Head Range |
|---|---|---|---|---|---|
| Submersible Pumps | enclosed / delta impeller options | Submersible Pump | heavy-duty volute, electric motor | up to 3in | up to 20,000 GPM, up to 450 ft head |
| Solids Handling Pumps | generic family (incl. 4NHTB, unconfirmed sheet) | Solids Handling Pump | heavy-walled volute, abrasive service | 3in-5in | 80-20,000 GPM, 10-350 ft head |
Sourced from Cornell Pump Company's own published pages (cornellpump.com/submersible-pumps/, cornellpump.com/solids-handling-pumps/). Model 4NHTB was read visually off Cornell's own printed performance-curve chart (BR-SUBMERSIBLE-2023.pdf) — plotting through roughly 250 GPM at approximately 270-380 ft TDH — and is a real lead, not yet a certified spec; a real project still needs the actual curve sheet or rep confirmation before final quoting.
Frequently Asked Questions
What's the duty range for Cornell Pump's submersible and solids-handling lines?
Cornell's own site publishes submersible pumps up to 3in solids, 20,000 GPM flow, and 450 ft head (enclosed and delta impeller options), with the broader solids-handling family covering 80-20,000 GPM and 10-350 ft head using heavy-walled volutes for abrasive service, 3in-5in solids capacity.
Is a specific Cornell model confirmed for LibertyCES duty points?
One real lead exists: model 4NHTB, read visually off Cornell's own published performance-curve chart (BR-SUBMERSIBLE-2023.pdf), plots through roughly 250 GPM at approximately 270-380 ft TDH. This is not yet a certified performance curve sheet — a real project would still need the actual 4NHTB curve sheet or rep confirmation from E-Water Solutions before final quoting.
Is Cornell or Barnes the better fit for high-head municipal sewage duty?
Cornell's published overall range extends further on paper than Barnes' confirmed 18/21 Frame data (up to 20,000 GPM and 450 ft head vs. Barnes' verified 2-30 HP range). But Cornell's specific model data (4NHTB) is a curve-chart read, not a certified sheet, while Barnes' 18/21 Frame specs come from real installation manuals.
