A modern paper mill factory based at the west of the country has been fighting for a long time with the reliability of a Sulzer-Escher E2K. These decomposers, or called De-inkers, get ink pulp from paper pulp and are essential for paper making. Fault, or failure, causes major problems. However, these occurred frequently caused by large water leakage from the stuffing box room. A lot of flush water was needed to flush and cool the packing. On average 1x per 3 month, the decoder was removed from the system and revised. This resulted in high maintenance costs and therefore a very low return. Sellon was asked to think and came up with an improvement proposal. This was found in replacing the packing with a S10 cassette seal + spiraltrac.
In November 2009, the solution was converted and returned. Since then, it has been working smoothly. No leakage, no bearing damage and additional benefit, only a fraction of water consumption is required to keep the seal environment clean. It is expected that the investment will be returned within 6 months.
The customer has so much confidence in this solution that has now been placed in order to build the 2nd de-inker
