APPLICATION
Beloit 36 DD Refiner

PROBLEM
Refiner sleeve had excessive wear below the lantern ring. Plant was unable to maintain packing leak rate and experienced short packing life. To replace sleeve also requires significant downtime of 8 hours. Costs to replace sleeve are as follows.

SLEEVE REPLACEMENT AND REPACK COSTS
Sleeve Cost $1,500.00
Labor 4 men 8 hours $22/hour each $704.00
Packing 6 rings 1727 and lantern ring $568.00
Total cost $2,772.00

SOLUTION
Install Enviroseal bushing and 370 carbon yarn packing. Enviroseal bushing replaces lantern ring and eliminates packing in the bottom of the stuffing box, there is no need to replace the sleeve. The time needed to do the repair is relatively short and can be done at a normal shutdown. The added benefits are reduced flush water usage and reduced packing leakage as well as extended packing life.

ENVIROSEAL BUSHING AND 370 REPACK COSTS
Enviroseal Bushing and 370 Packing $1,987.25
Labor 2 men 2 hours $22/hour each $88.00
Total Cost $2,075.25
Initial savings $696.75

SUMMARY
Plant has since reordered Spraltrac and packing to convert 2nd Refiner.
