Product overview
Sefar manufactures centrifuge liners and filter bags engineered for precise separation, regulatory compliance and easy handling in pharmaceutical, chemical, food and mineral processing. Ready-to-install, custom-fit solutions reduce downtime and ensure consistent performance across centrifuge types.

Key benefits

• Optimized fit and secure sealing to minimize particle bypass and wear.
• Pre-assembled designs for rapid changeovers and reduced downtime.
• Materials and constructions selected for high mechanical strength, efficient drainage and extended filter life.

Product types

• Centrifuge endless liners — Seamless constructions for smooth operation and reduced wear in high-throughput processes.
• Centrifuge open liners — Open designs for optimized fit and operational flexibility.
• Inverting centrifuge liners — Robust, flexible liners designed to withstand repetitive inversion discharge cycles.
• Centrifuge bags — Custom-fit filter bags with reinforced cone and collar details adapted to various discharge methods.

Filter media technology
Wide selection of filter fabrics with multiple weave types and polymer options optimized for process conditions, delivering high separation efficiency, mechanical stability and consistent filtrate clarity.

Fabric technologies

• SEFAR TETEX DLW® (Double-Layer Weave) — Precise particle retention with integrated support for efficient drainage, good cake release and long service life; suited for high-throughput demanding processes.
• SEFAR TETEX® MONO (Monofilament) — Low clogging risk, easy cleaning and excellent cake release; high-strength option for frequent changeovers.
• SEFAR TETEX® MULTI (Multifilament) — Fine particle capture and high filtrate clarity with a soft surface that protects fragile solids.

Product features

• Filter pore range: typical nominal range approx. 5–150 µm (process-dependent).
• Material & compliance: certified materials and manufacturing controls to support food-contact, GMP, FDA, EU and ISO requirements where applicable.
• Mechanical design: engineered for heavy cake loads and high rotational speeds with enhanced strength and stability.
• Chemical & thermal resistance: available across a broad range of polymers for specific exposures.
• Traceability & packaging: in-house yarn production, controlled manufacturing and cleanroom packaging for regulated industries.

Manufacturing & product details
Ready-to-install, custom-engineered liners and bags with permanent markings for traceability. Options include reinforced edges, cone/collar customizations and endless (seam-free) welding to eliminate weak points and ensure reliable installation.

Compatible equipment

• Compatible with a wide range of centrifuge manufacturers, e.g. Andritz KMPT, ComiCondor, Ferrum, Heinkel, Matsumoto, Rousselet, Robatel.

Applications
Designed for pharmaceutical, chemical, food & beverage, mineral processing and other industrial separations requiring precise particle retention, compliance and reliable changeovers.
