Cornell has delivered dependable, reliable, and efficient dewatering pumps for decades. Our pumps are up to the toughest challenge, whether it’s coarse abrasives, rapidly-changing water levels, high head requirements or a combination of factors. Our products are used successfully in long wall, traditional pier and beam, pit, and strip mining applications.
On Mining pumps, the unique pushed-out rectangular design features of the Cornell frame will let you know it is Cornell pump.
The innovative features of Cornell pumps have real benefits in mining applications.
- The Cycloseal sealing system works to keep grit and abrasives away from the seal area, extending seal life and reducing maintenance.
- Cornell Run-Dry system protects your pump when running in a dry condition, due to loss of prime.
- Redi-Prime adds automatic priming and re-priming to pumps in all types of applications.
- Double Volutes on pumps balances pressure on volute walls to achieve higher heads and lessen stress on the pump shaft, bearings and seals.
- Pumps available in CD4MCu are more abrasion-resistant and have improve solids handling.
Use the guide below to compare the ruggedness of Cornell series pumps and select the best Cornell pump for your mining application.
SP-Series Pumps
Cornell’s SP Series Slurry pump brings patented Cycloseal® technology to the mining process industry. Adding to the diverse range of mine dewatering pumps, The SP Series Slurry pump offers a Cornell solution to abrasive applications throughout the mill process. Available in rubber and metal lined configuration to handle various particle sizes, and pH requirements.
MP-Series Pumps
MP-Series Pumps are designed to handle coarse abrasives while providing robust service life in a slurry pump. Cornell Pump Company’s MP Mining Pump Series combines 70 years of innovation in pump manufacturing and design, with our highly regarded patented Cycloseal® technology. Offering high operating pressures, the MP pumps are specifically designed for coarse abrasive slurry applications such as sand, gravel, coal, manure, and mine dewatering. The oversize shafts, thick volutes, high-chrome white iron impellers, and other features allow it to operate in harsh conditions longer than a standard slurry pump.
The MP series incorporates the unique pushed-out rectangular design features of the Cornell frame, letting you know it is quality Cornell pump.
SM-Series Pumps
The SM series are hard metal slurry pumps. All SM pumps have a standard pressure rating of 600 PSI for high head and multistage series pumping applications. High chrome white iron alloy is the standard material of construction for all wet end components. A unique adjustable suction wear plate incorporates the newly patented Cycloguard feature to reduce recirculation for longer wear life.
Look for the distinctive appearance SM Pump, with the angular, muscular frame, to know it’s a high quality Cornell pump.
N-Series Solids Handling Pumps
Cornell’s N-series solids handling pumps are available in discharge sizes from 1.25″ to 30″, and are designed to handle difficult solids handling applications. A range of mounting configurations are available, from close-coupled, SAE engine-mount, and horizontal frame-mount, to vertical and vertical coupled. Featuring enclosed impeller (2” to 10” solids, and flows up 40,000GPM), N-series can also be fitted with a delta impeller to handle stringy materials, rags, etc. Robust and reliable, the N-series has more than 30 years of service as a waste-water handling favorite of the industry.
Hybrid Pumps
Cornell Pump hybrid pumps are able to handle dirty water and viscous slurries. They can handle small solids and high operating pressures for up to 800′ of head. Available in discharge sizes from 2″ to 8″.
Self-Priming Pumps
Cornell’s popular self-priming series pumps are the most efficient in the industry. Combined with our patented-Cycloseal® back plate technology, these pumps are durable, powerful, and energy efficient.
Durable, reliable, and easy to maintain, the STX, STH, and STL self-priming pumps are an excellent option for many applications including waste water, slurry, and water transfer.
CD4MCu Pumps
CD4MCu is a stainless steel with corrosion resistance equal to or better than 316 SS, but with double the yield strength. It’s a duplex (two phase) stainless steel, while common grades of stainless steel, such as 316, are single phase. This provides the corrosion resistance of 300 series stainless steel with the strength and hardness of 400 series stainless steel. CD4MCu allows pumps to be used in more abrasive applications with better resistance to corrosive cracking and pitting. Features include:
- Corrosion and pitting resistance
- Higher strength than standard grades of stainless steel
- Improved ductility and weldability
- Better resistance to embrittlement
