Lower Operating Costs
Efficient pumps consume less energy to move the same amount of fluid. That translates into immediate savings on electricity or fuel—and over months or years, those savings add up significantly. The STX’s advanced hydraulic design and optimized impeller profiles reduce energy use without sacrificing performance.
Cornell’s self-priming pumps are up to 8% more efficient than the competition. Using a simple assumption—a 100 HP motor operating 2,500 hours per year—this results in a power savings of approximately 6 kW per hour, or nearly 15,000 kWh annually. Even at low energy rates, that equates to over $1,600 in yearly savings. With higher electricity costs, the savings can exceed $3,000 per year.
Built for Long-Term Reliability
STX-Series pumps feature a removable rotating assembly, external wearplate adjustment, and replaceable wear parts—design elements that help maintain peak performance and extend service life. When a pump stays efficient over time, it means fewer costly shutdowns and less frequent part replacement.
Resilient in Tough Environments
Cornell’s robust construction—available in ductile iron and CD4MCu—makes the STX ideal for demanding environments. Whether handling abrasive slurries or solid-laden water, the STX maintains its efficiency while resisting wear and performance degradation.
Easy Maintenance, Less Downtime
Features such as the external coverplate adjustment, clean-out access, and dry-run-capable mechanical seal reduce service time and eliminate the need for extensive disassembly. These design choices help operators maintain efficiency without taking the pump offline for extended periods.
Engineered for Efficiency from the Start
Cornell doesn’t rely on aftermarket accessories or add-ons to enhance pump performance. The STX is designed from the ground up for energy efficiency and reliable priming. That built-in advantage pays off every time the pump runs.
Efficiency is not just a feature—it’s a cost-saving, performance-enhancing necessity. With STX self-priming pumps, you get the durability, reliability, and high efficiency required for demanding applications like construction dewatering, industrial processing, and municipal bypass.
