ROBASEAL®-S sealing strip and end deckles

Premium rubber graphite-based material for
heavy-duty sealing strips. ROBASEAL-S together
with highly temperature-resistant silicone oil
considerably reduces the amount of water
lubrication required while significantly increasing
service life and ensuring functionality for
the entire usage period.

 

  • Increased service life (less friction, less wear)
  • Reduced amount of water lubrication
  • Longer service cycles
  • Lower energy consumption

 

Application

All suction rolls.
Saving energy and water lubrication and increasing service intervals.
 

Doubled service life

ROBASEAL-S can increase the service life by up to 100% compared with ROBASEAL-A while maintaining the
same operating parameters (spray water volume, loading pressure, vacuum).
 

Reduction in water lubrication

Suction rolls require approx. 10 m³ water lubrication for each meter in width over 24 hours in order to lubricate the
sealing strips. The unique silicone admixture in ROBASEAL-S enables the water lubrication volume to be reduced
by 30% – with no impact on service life.

 

1/3 reduction in water lubrication means a 30% reduction in the risk of remoistening with no impact on endurance
and also lowers production costs!  

  

Supplying a full sealing strip package

Röchling LERIPA Papertech is the only supplier to offer all the components and materials suitable for use as
suction roll seals. The sealing strip alone does not provide a functional sealing unit for suction rolls. Only the
right loading tube and sealing strip holder with a sufficient amount of flexibility and chemical resistance ensure

the level of protection required.

 

As we supply a complete unit, our customers find the ordering and stock processes much easier and
are assured of flawless sealing units. The flexible modular system also ensures rapid turnaround times.
Why not experience the unrivaled quality of this solution for yourself?
