To Whom It May Concern,Re: WeeSeal Cage for injectable packing compounds
Water reduction is one of many goals that this mill has. We are looking at ways to reduce water usage through water reuse and water elimination. A major concern we had on the environmental side was the many pumps that we had with regular packing. These continued to leak even after they were repacked. This not only wasted water but was a concern in that our product leaked out and had a potential to contaminate both the surrounding ground and during the rainy season contaminate the storm water. This was unacceptable.
Injectable packing has been tried without success in the past. The WeeSeal Cage has corrected the problems enabling the successful use of injectable packing.
There are 18 applications installed and operating in our mill. On the effluent side we have the WeeSeal Cage on the North and South outfall pumps and the North and South clarifier pumps. These 4 pumps are Worthington 6FRB’s.
The use of injectable packing with the WeeSeal Cage has completely stopped these pumps from leaking 3 to 4 gallons per minute externally. Seal water has been removed from these pumps.
Noted benefits of this conversion:
No external leakage during operation - greatly improved housekeeping
No leakage internal to the process - no undesired dilution.
Potential to significantly reduce water consumption.
No modifications to the pumps are required.
Significantly less expensive than mechanical seals.
Potential water savings in the clippings area only of the mill is approximately 20 million gallons per year. This is not only a cost savings in water purchased but also is water that does not have to be treated in a wastewater system.
We plan to install the WeeSeal Cage and injectable packing in all pump applications and will experiment with high temperature applications such as condensate pumps.
Process: We are a paper mill producing 625 tons per day of corrugating medium from 100% recycle fiber.
