Suction roll seals
Metso's suction roll seals are marketed under the brand name FlexSeal
. FlexSeal is used as the standard seal material for all new suction rolls, and as a replacement for conventional seal strip materials in the case of older rolls.
FlexSeal is a rubber-graphite based material that also includes some special components for such beneficial seal strip properties as flexibility, excellent wear resistance and low noise.
Metso manufactures FlexSeal strips completely in-house, all the way from the mixing of rubber to vulcanization and machining. This facilitates continuous related research and product development.
FlexSeal can be used on all paper, board and tissue machines and drying lines, and at all suction roll sealing positions.
