Overview
Sefar rotary drum filter belts and panels are engineered for vacuum and pressure drum filters. They are custom fabricated for precise fit, reliable performance and expert technical support to optimize solid–liquid separation processes.

Trusted Performance for Every Drum Filter Design
Smooth operation, precise belt tracking and tailored constructions ensure consistent filtrate clarity, efficient cake release and easy installation to maximize uptime.

Applications & Benefits
Rotary drum filters are used for clarification, dewatering and cake washing across multiple industries. Sefar solutions reduce maintenance, support continuous operation and deliver repeatable filtration results.

• Typical industries: food (starch), chemical, mining & mineral processing, environmental, life sciences.
• Operational benefits: improved cake release, lower maintenance, minimized product loss.

Product Types

• Rotary vacuum drum filter panels: custom panels for effective dewatering and cake washing with reliable discharge behavior.
• Rotary pressure drum filter panels: engineered for high-pressure applications with mechanical stability and high filtration performance.
• Rotary drum filter belts: ready-to-install belts with optimized edges and closures for stable tracking and continuous operation.

Filter Media Technology
Our portfolio covers double-layer, multilayer, monofilament and multifilament weaves selected according to process requirements for vacuum and pressure applications.

Highlighted Fabrics

• Double-layer weave (SEFAR TETEX DLW®): fine filtration layer with integrated drainage support — high throughput, good cake release and stable tracking.
• Multifilament (SEFAR TETEX® MULTI): excellent particle retention, low filtrate turbidity and good cleanability.
• Monofilament (SEFAR TETEX® MONO): smooth surface, clog-resistant construction for fast cake release and easy cleaning.

Key Product Features

• Process compatibility
  Multiple fabric constructions and polymers to match slurry properties, pH and equipment types.
• Filtration efficiency
  Controlled pore structures for high throughput, consistent filtrate clarity and effective cake release.
• Fast installation
  Ready-to-use belts with optimized closures and edge profiles for quick, safe installation to reduce downtime.
• Product loss prevention
  Particle-tight closures and precise fit to minimize bypass and leakage.

Design & Installation Considerations

• Matched fabric thickness for groove designs and chaulking-in to prevent slippage.
• Edge guiding profiles (e.g., mushroom-shape) to improve tracking and reduce wear.
• Particle-tight, leak-free closures to protect vacuum integrity and filtrate cleanliness.
