Thanks to the
excellent relation between our distributor Sizonke Trading and the management of
our distributor in South Africa, it was decided to install different Dualpac configurations on 4
different equipments.
Case 1: On the Bottom Ply Machine Refiner (used for Pulp) 4 Series Hard through Sleeve With a configuration on the sleeve is Chesterton 15.9mm, 211 packing 5 Rings.
Case 2: On the Gum Refiner
(Pulp), the configuration on the sleeve is with Spiraltrac and Chesterton
19.1mm 2211 Packing 3 Rings.
Case 4: Bottom Ply
Mixed Stock Chest Pump (Allis Chalmers GR2) (Pulp) Sappi Sleeve with PTFE Lantern
Ring and Chesterton 12.7mm 2211 Packing 6 Rings.
On
the Paper Machine, the distributor used previously a Superset with 1830, the service life
was good (1-2 years) . Because of corporate decision and price
reasons Distributor in South Africa changed to competitor packing which started to leak after 3-5
month of operation. Following the advice from Sizonke, the distributor came back by
seeing the opportunity in a completely new packing design 2211.
Digester
area, our distributor used a combination of Chesterton 477-1T/1400R and 1830SSP
with service life of 1 year shut to shut. Due to the same reason mentioned above
our distributor changed to competitor packing which started to leak after 6-8 month of operation.
