Product Overview

Our Drum Wire Screen is a high-efficiency Johnson-type screen used for trapping solid particles and impurities while maintaining optimal fluid or gas flow. The unique V-shaped cross-section of the wedge wire creates continuous slots that widen inwardly, facilitating easy cleaning through back-washing and preventing particle entrapment.

Ideal for harsh working conditions, this drum screen is manufactured using automated machine tools that fusion-weld the profile wire onto support bars. Whether used in rotary drum filters or as static filter inserts, it provides a long service life and stable filtration precision for the most demanding environments.

Key Advantages

Controllable Filtration Precision: Customizable gap widths allow for the precise separation of specific particle sizes.
Anti-Clogging Design: The V-wire profile minimizes surface contact points, making it highly effective for filtering slurry and medicinal liquids.
High Aperture Ratio: The back width of the sieve strip is optimized to maximize the free flow area and reduce pressure drops.
Exceptional Mechanical Strength: Fusion-welded construction and internal support rods provide the stiffness required for deep well and mining applications.
Corrosion & Wear Resistance: Specialized cold-rolled stainless steel ensures durability in humid, acidic, or high-pressure environments.

FAQ

Q: Can these drum screens be used for high-pressure filtration?
A: Absolutely. Our drum screens are fusion-welded and reinforced with internal support rods, enabling them to withstand differential pressures up to 6 Kg/cm².
A: For municipal wastewater, SS304 is usually sufficient. However, for industrial sewage containing chemicals or acids, we recommend SS316L for its superior corrosion resistance.
A: We can manufacture drum screens with an Outer Diameter (OD) of up to 1200 mm.
A: Absolutely. We can design the flange and internal support structure according to your existing equipment’s specifications to ensure easy installation and maximum strength.
