Valmet seal flow upgrade improves suction roll operation

Aug 12, 2015

Pekka Kivioja is Valmet's director of Roll Maintenance There is a continuous need for paper manufacturers to reduce their environmental impact. Contributing to this need, Valmet Suction Roll Upgrade Seal Flow is an easy upgrade for suction roll lubrication showers.

"Valmet's new seal flow technology reduces water consumption by as much as 50%, while maintaining or improving lubrication results," says Pekka Kivioja, director of Roll Maintenance at Valmet.

Worn, aged and outdated showers and nozzles lead to substandard lubrication results and consume excessive amounts of water. The new Valmet Suction Roll Upgrade Seal Flow axial seal lubrication shower from Valmet features a design which improves the lubrication process, as well as reducing the roll's environmental impact through significantly reduced water consumption.


  • Reduced water consumption
  • Improved moisture profiles
  • Extended shell, cover and axial seal lifetimes
  • Longer roll machine time
  • Reduced roll maintenance costs
  • Quick payback time

In addition to improved lubrication results, many applications show an improved moisture profile and reduced costs of shower water preparation. Kivioja gives an example: "On a paper or board machine, this could mean savings of as much as 2,500 to 5,000 euros per roll meter per year, resulting in average savings of 100,000 to 200,000 euros a year on a ten-meter wide machine that has four suction rolls." The improved shower functionality also has a positive effect on the lifespan of the axial seal and on the suction roll shell.

This modification is now available with suction roll maintenance through Valmet's extensive roll service network. For more information, contact your Valmet representative.
