Cycloseal® is Cornell’s patented, flushless sealing system — developed to solve seal failure in municipal pumps and in service since 1994. It needs no flush water, eliminates leaks, and uses inexpensive, easy-to-change Type 1 or 2 mechanical seals. Each pump that requires flush water can incur costs of $10,000 or more.
What flush water really costs
A typical 6” pump uses about 3 gallons per minute — over 1.57 million gallons a year. Larger 8” and 16”–24” pumps can use 8 million gallons or more per year.
| Flush rate (GPM) | Gallons / day | Gallons / year | Annual cost at $0.02/gal |
|---|---|---|---|
| 1 | 1,440 | 525,600 | $10,512 |
| 3 | 4,320 | 1,576,800 | $31,536 |
| 5 | 7,200 | 2,628,000 | $52,560 |
| 8 | 11,520 | 4,204,800 | $84,096 |
Based on typical wastewater-plant water prices of $0.02 per gallon. In some locations water costs as much as $0.22 per gallon — nearly $35,000 a year in flush water for the same 6” pump. Multiply by pumps per site and sites per organization.
No flush water or packing
Saves expense, service time and drips — no external water flush, filters, grease cups or piping.
Extended seal life
Sometimes tripling expected seal life in demanding jobs like manure slurry, starch recovery and food processing.
Run-Dry™ option
Lubricates seal faces even with no liquid in the casing — ideal if a pump may run dry or lose prime.
Better in abrasive service
More resilient than packing and standard mechanical seals against abrasives.
Greater reliability
Positive seating lets you confirm the seal is fitted correctly, for longer service intervals.
Lower maintenance cost
Longer-lasting seals mean less downtime and lower cost over the pump’s life.
