Paper mill process pump shaft cartridge seal


The customer was experiencing a mean time between failure of the mechanical seals of 3 - 6 months. This was resulting in excessive maintenance and downtime, in turn leading to rising costs.

James Walker solution

A KlickFix cartridge was installed in an effort to prolong the seal life cycle and reduce the costs associated with regular adjustment and replacement.

The KlickFix uses a sequentially deployable sealing lip system and contains five lips. As and when the stored lips need to be utilised, the process can be undertaken in a matter of minutes.

Results and benefits

After over 10 months, the KlickFix cartridge is still in operation using the first lip. With a further four lips ready to be deployed when required, the cartridge is offering a massive improvement in seal life cycle. The customer has already reported cost savings through reduced downtime and maintenance.
