CORNELL PUMP COMPANY PATENTED LONG LASTING, LEAK-FREE FLUSHLESS SEALING SYSTEM

CYCLOSEAL® SEALING SYSTEM CYCLOSEAL® DESIGN: The patented, premium mechanical seal system that distinguishes Cornell Pumps from all others. One of the main reasons Cornell Pumps have a service advantage 20 YEARS OF EXCEPTIONAL SEAL TECHNOLOGY compared to competitors is our patented Cycloseal design that Cycloseal grew out of a need to address municipal seal failure. In 1994, the idea that you could have a mechanical seal that didn’t require a water flush, and wouldn’t leak, was revolutionary. Twenty years later, that idea still resonates with customers — the ease of care and reliability...

CYCLOSEAL® SEALING SYSTEM CYCLOSEAL® BENEFITS No Flush Water or Packing: Through the backplate and sweeping vanes, Cycloseal requires no flush water or packing, saving expense, service time, and messy drips. Extended Seal Life: Cornell’s Cycloseal design has proven itself in the toughest applications, from manure slurry, starch recovery, and clear water, to food processing and self-priming applications – in some cases more than tripling the normally-expected seal life. Run-Dry™ Option: All pumps with Cornell’s Cycloseal system can be equipped with an optional Run-Dry feature, which serves...

CYCLOSEAL® SEALING SYSTEM HOW CYCLOSEAL® WORKS Cycloseal isn’t just a seal, but rather a sealing system. Designed by Cornell engineers in the 1990’s, and refined over the years, the elegance of the system is that it utilizes a traditional Type I or II Mechanical Seal in such a way that the Cycloseal system provides much longer life than the seal would normally experience. Through a pressure gradient, the Cycloseal system pulls grit and material away from the seal face, leaving it in an environment with fewer particulates than a standard seal. Cyloseal creates this environment with these...

ADDITIONAL OPTIONS RUN DRY™ AND REDI-PRIME® OPTIONS All pumps equipped with Cornell’s Cycloseal® sealing system have an optional Run-Dry™ system, designed to lubricate the seal faces in even when there is no liquid in pump casing. Nearly all of the Cycloseal-ready pumps also can employ Cornell Redi-Prime technology, a mechanically-driven, low-maintenance, high-volume vacuum pump system for rapid priming and repriming. RUN-DRY™ The Cornell Run-Dry system is a unique, state-of-the-art solution for providing continual lubrication to mechanical seals. Run-Dry provides a gland on the back side...

CYCLOSEAL® APPLICATIONS CORNELL’S CYCLOSEAL SYSTEM IS USABLE IN ALL THESE MARKETS: SLURRY IN THE TEST LAB VOLUTE SCOURED—BUT CYCLOSEAL® BACK PLATE/ MECHANICAL SEAL STILL HAS PRIMER ON IT! In preparing to launch the SP Series of slurry pumps, Cornell conducted tests of a 3SP pump in our test lab. The 3” pump was subjected to over 1,500 hours of testing, with a 30 percent sand mixture. The slurry mixture was switched every 50 hours to maintain sharp edges on the sand. The pump functioned flawlessly. The volute, impeller, and expeller were all scoured by the mixture. The volute shows signs of...
