liquid2-layershigh-efficiency

Overview
Sefar rotary disc filter covers are manufactured from high-performance materials for a wide range of solid-liquid separation processes in the mining and refining of minerals. They are designed and supplied as ready-to-install, customized covers that fit OEM equipment (rotary vacuum and hyperbaric disc filters) and are intended to maximize filtration efficiency, ensure stable cake thickness and meet target cake moisture levels.

Value Proposition
Engineered for Optimum Filtration Efficiency

• Effortless Installation
  Simple mounting and extended durability mean less maintenance time and increased productivity.
• Impressive Capacity
  High-volume processing with exceptionally dry filter cake significantly boosts output efficiency.

Product Description
Sefar covers provide reliable filtration solutions for challenging rotary vacuum and hyperbaric disc filter applications. They are customized to perfectly fit OEM equipment and maximize filtration efficiency for mineral processing applications including concentrates and tailings. Covers are engineered to deliver high throughput, short cycle times, drier filter cakes and consistent performance even under abrasive slurry and aggressive chemical conditions.

Materials & Fabric Technology
Available fabric technologies and constructions highlighted on the page include:

• SEFAR TETEX DLW® (double-layer weave) — combines precise particle retention with a strong support layer for robust performance and efficient drainage. Ideal for demanding processes requiring high throughput, good cake release and long filter life.
• SEFAR TETEX® MONO (monofilament fabric) — offers low clogging, easy cleaning and excellent cake release, ensuring high, stable filtration rates with reduced downtime.

Highlights / Functional Benefits

• Made to Fit
  Precisely dimensioned for easy mounting, operational reliability and low maintenance.
• Precisely Dimensioned
  Exact fit for reliable sealing and easier installation on existing disc filter segments.
• Innovative Mounting Options
  Custom installation features (examples presented include velcro and zipper closures) for fast setup and secure sealing.
• Reinforced Edges
  Enhanced durability to reduce holing and extend service life, improving operational efficiency on worn filter segments.

Key Product Features

• Filter Cake Dewatering
  Engineered weave structures support rapid liquid drainage and minimal residual moisture, enabling drier filter cakes and reduced downstream drying costs.
• Filter Cake Release
  Special surface finishes and fabric constructions ensure easy cake discharge, minimize cloth blinding, and maintain stable cake thickness.
• Filter Efficiency and Capacity
  Precision-engineered fabrics with optimized pore sizes and high permeability ensure excellent particle retention, clean filtrate and high throughput for faster filtration cycles.
• Chemical & Thermal Resistance
  Manufactured from a range of polymers to meet specific chemical and thermal demands for stable long-term performance.
