The ideal QualiFlex press sleeve for every paper grade
For every paper grade, the QualiFlex family offers the ideal choice of sleeve. QualiFlex Crest is characterized by good properties and provides reliable performance – both in dewatering and lifetime. QualiFlex Crown allows you to go even a step further to reach the next performance level. And our premium shoe press sleeve, QualiFlex QRun, reacts stably to compressions that occur especially in board, packaing and pulp machines.
Our new press sleeve QualiFlex QView is designed to make the invisible, visible! So, how does it work?
The special color of the QView press sleeve enables the inside of the press sleeve to be visible from the outside.
Minimal abrasion and maximum runtimes
With QualiFlex QRun, Voith offers a shoe press sleeve that reacts stable to compressions. The result: fewer failures of shoe press sleeves. The improved elasticity of QualiFlex QRun guarantees high durability and thus reduces cracks and their propagation. These two properties ensure longer and reproducible running times.
Ultimate dewatering designed specifically for your tissue machine
With CrestT and CrownT Voith offers two superior press sleeves for tissue shoe press applications which enable to obtain stable machine operating conditions and efficiency. Selected polyurethane materials ensure the highest possible abrasion resistance under challenging temperature condition. Open area and void volume can be designed exactly to your needs.
QualiFlex CrestT for tissue machines shows very good material properties regarding wear resistance and performance stability. It features the proven structure and performs reliably even under the harsh conditions of a tissue shoe press.
QualiFlex CrownT is based on a well-proven concept as well, with excellent abrasion resistance properties. The special heat resistant material formulation makes this press sleeve the perfect choice for very demanding applications.
Excellent dewatering, tailored to your pulp machines
Through its smooth surface, the focus of QualiFlex CrestC is on high and reliable lifetime. The one-layer design using high quality polyurethane reduces the risk of delamination and the occurrence of cracks to a minimum.
For ultimate dewatering performance, QualiFlex CrownC is recommended with its unique blind drilled surface. It temporarily stores more water than any conventional sleeve. This surface design prevents water backflow in generally slow running pulp machines.
Get the best dewatering performance for your graphic paper machine
Good abrasion, crack and impact resistance provide more than the usual market lifetime and performance. Technical expertise, tailor-made surface designs and stability come along with the good material properties of QualiFlex CrestW.
With its specific focus on the individual key performance indicators (abrasion, crack and impact resistance), the tailored material properties of QualiFlex CrownW take the sleeve’s performance to the next level while considering the specific requirements of your machine.
Optimum dewatering performance for your board machine
QualiFlex CrestK is characterized by good abrasion resistance, low risk of crack occurrence and consistent performance due to high impact resistance.
QualiFlex CrownK raises the bar for long-time effective void volume and reliable achievement of the highest lifetimes. Its enhanced abrasion and impact resistance are the key factors.
Optimum and efficient dewatering for your packaging machine
Good abrasion, crack and impact resistance provide more than the usual market lifetime and performance. Technical expertise, tailor-made surface designs and stability come along with the good material properties of QualiFlex CrestP.
With its specific focus on the individual key performance, the tailored material properties of QualiFlex CrownP take the sleeve’s performance to the next level. As new benchmark it achieved record lifetime even with obvious signs of local deformations after impact.
