A paper mill in the middle of the country has high costs on refiner seals.
1st; A lot of flush water
2nd; A lot of leakage paper stock and cleaning costs.
3e; High maintenance costs due to wear
4th; Packing chamber shifts to the shaft by setting
the refiner plates causing accelerated packing leakage.
The Sellon solution
We have locked up the Chesterton CMS 2000 in the stuffing box by means of a top and bottom ring of Chesterton gasket 1730 millpack.
There is no need for a flush here.
The CMS can handle the axial displacement of 20-30mm.
