KlickFix offers more than 3 times the life of mechanical seal
The KlickFix® cartridge seal with sequentially deployable sealing lips – has been specifically developed around pump sealing applications in the paper and pulp industry and this case study demonstrates exactly why there is so much excitement within the industry about the future for this product.
When a mechanical seal fails in this type of environment it can cause significant problems, requiring a great deal of clean-up. The mechanical seal in place on the customer's pump in this case had a typical life of just 9 to 11 months and required a constant clean water flush of some 20 gallons per hour.
The KlickFix replacement was of an 8 lip configuration with the first 2 lips engaged on installation. Requiring just 2 gallons of flush per hour (a 90% reduction over the previous mechanical seal), this unit has now been in continual service for more than three and a half years with no leakage.
