Valmet, Finland, has introduced its new SealFlo, an "easy upgrade" for suction roll lubrication showers. Pekka Kivioja, director of Roll Worn, notes that "Valmet's new SealFlo technology reduces water consumption by as much as 50%, while maintaining or improving lubrication results. Aged and outdated showers and nozzles lead to substandard lubrication results and consume excessive amounts of water. The new SealFlo axial seal lubrication shower features a design that improves the lubrication process, as well as reducing the roll's environmental impact through significantly reduced water consumption." 

 

 

 

In addition to improved lubrication results, many SealFlo applications show an improved moisture profile and reduced costs of shower water preparation, according to Valmet. Kivioja gives an example: "On a paper or board machine, this could mean savings of as much as EUR 2,500 to EUR 5,000 per roll meter per year, resulting in average savings of EUR 100,000 to EUR 200,000 a year on a 10-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.
