Increasing MTBR for CI0₂ Applications in the Pulp & Paper Industry


Sponsored by: John Crane

Overview:  In this webinar, John Crane will discuss 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 ClO2 transfer pumps. We’ll show how the use of Dynamic Lift Up-stream Pumping (USP) 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 USP Dynamic Lift non-contacting seal face treatment to improve MTBR and to reduce water waste. As a result, the mill has increased MTBR (mean time between repair) by 500% and is saving up to 1 million gallons of water per year, per seal, since the upgrade was completed.


Learning Objectives:

Demonstrate how adding Dynamic Lift Up-stream 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 (Mean Time Between Repair)
  • Other Pulp & Paper applications for this technology

Who should watch:

  • Process / Plant Managers
  • Maintenance / Reliability Engineers
  • Anyone involved in the operation and maintenance of pulp/paper plants
  • Pulp/Paper plants
