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

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 EUR 2,500 to 5,000  per roll meter per year, resulting in average savings of EUR 100,000 to 200,000/y 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.
