To Whom It May ConcernRe: WeeSeal Cage for injectable packing compounds
The subject cage was first installed in our Worthington 8FRBH-152 machine chest stock pump during a shutdown in October 1995. This was a new installation for the pump. It had not previously had standard packing. There is presently no seal water connected to the pump. It does not leak (not even a drip) in operation. (During shutdowns, the seal drips somewhat, but this stops at start-up). The previous pump had standard packing rings and leaked approximately 3 gallons per minute externally.
Injectable packing has been tried without success in the past. The WeeSeal Cage has corrected the problems enabling the successful use of the injectable packing.
Since the October replacement of the machine chest pump, three other pumps in the paper machine area were fitted with the WeeSeal Cage: The East and West saveall seal pit pumps (Worthington 6CNG-84), and the #2 white water pump (Worthington 6FRBH-142). 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 the pumps.
There are 14 other applications installed and operating in our mill outside the paper machine.
Noted benefits of this conversion are:
No external leakage during operation - greatly improved housekeeping.
No leakage internal to the process - no undesirable dilution or heat transfer.
Potential to significantly reduce water consumption.
No modifications to the pump are required for installation.
Significantly less expensive than mechanical seals.
We plan to install the WeeSeal Cage and injectable packing in all stock pump applications and will experiment with high temperature applications such as condensate pumps.
Process: We are a corrugating medium paper machine producing 625 tpd - 26# to 40# per 1000 sq. ft. from 100% recycle fiber.
