Increasing MTBR for CI02 Applications in the Pulp & Paper Industry

In a recent webinar, John Crane panelists discussed how a southeastern pulp and paper mill used one seal standard design to serve both low and high pressure sealing on its chlorine dioxide bleaching processes CI02 transfer pumps. They also demonstrated how upstream pumping technology allows the creation of a high pressure, low volume lubrication delivery system, providing a clean environment for the seal to operate which improves pump performance and mean time between repair (MTBR).

The mill chose John Crane’s engineered Type 5620 upstream pumping non-contacting seal face treatment to improve MTBR and reduce water waste. As a result, the mill has increased MTBR by 71% and is saving up to 63,000 gallons of water per year, per seal, since the upgrade was completed.

Over the course of this webinar, Pearley Lachance, Mike Compton and Nolan Anderson of John Crane demonstrated how adding upstream pumping face technology to mechanical seals improves processing and reduces seal wear by: 

• Optimizing mechanical seal performance

• Reducing friction and seal wear for increased uptime

• Conserving water

• Increasing MTBR
