For best total performance, two factors must be achieved: consistent long life and optimal dewatering. Abrasion and impact resistance are the keys to achieving reliable high lifetimes. Stable grooves that provide true, full void volume are vital for maximum dewatering performance. Under specific challenges at especially lower speeds our unique blind-drilled surface pattern optimizes efficiency and prevents water backflow without fail. The proven stability and reliability of QualiFlex CrestK is further exceeded by the enhanced abrasion, crack and impact resistance of QualiFlex CrownK.
With QualiFlex CrestK and QualiFlex CrownK, Voith offers a large variety of surfaces. Open area and void volume can be designed exactly to your needs.
