Spiral Pressure Belt

 

 

Polyester spiral pressure belts are heat-set at exacting temperature and tension to give maximum operation stability. It is designed for use in solid/liquid separation, as well as sludge dewatering for vacuum and multi-roll belt presses. The unique spiral weave patterns offer rapid drainage and outstanding cake release.

 

PFM polyester spiral pressure belt offers the following advantages:

• Acidic resistance,
• Alkaline resistance,
• Corrosion resistance
• Temperature resistant 
• A long lifespan of using.
• Stronger than common carpet and cavas
• Smooth surface of mesh,
• Strong bursting strength,
• Good permeability,
• Excellent conduct electricity and saving energy.
• Easy installation and without trace,
• Strength can reach 100% compare with general mesh.
