Horizontal pressure leaf filters feature a horizontal pressure tank containing circular leaf elements stacked along a central hollow discharge shaft or supported on internal carriage rails. During operation, slurry fills the vessel and forms filter cake on the horizontal or near-vertical faces of each circular element.
Our Horizontal Leaf Filter Elements are specifically built for horizontal tank configurations.
Constructed with heavy C-channel outer framing, precision-machined shaft insertion hubs, and heavy-duty 5-layer mesh matrices, these elements resist axial compression and torsional shear when the central shaft rotates or vibrators initiate cake discharge. Precision-machined hub seals guarantee a leak-free interface with the central filtrate collection shaft under differential pressures up to 6 bar.

Heavy Horizontal Leaf Elements vs. Standard Circular Replacements
Upgrading to structural-grade horizontal filter leaf elements provides critical operational advantages:
| Operational Parameter | Standard Circular Replacements | Our Heavy Horizontal Leaf Elements |
| Shaft Hub Sealing | Stamped metal or single-gasket hub | CNC-Machined Solid Hub with Double O-Rings |
| Axial Stack Resistance | Distorts under shaft clamping force | Heavy Heavy-Duty Core (Zero hub distortion) |
| Rotational Shear Stability | Weak perimeter seams split during rotation | Continuous TIG Perimeter Welds (High torsional strength) |
| Cake Release Efficiency | Flexible frame dampens vibration | Rigid Chassis Transfer (Rapid, complete cake drop) |
| Shell Clearance Fit | Inconsistent outer radius limits cake space | CNC Laser-Cut Profile (Maximizes vessel cake volume) |
| Re-meshing Longevity | Frame warps upon disassembly | Heavy Re-meshable Frame Chassis (Multi-cycle life) |
Key Performance Advantages Rooted in Our Manufacturing Process
● CNC-Machined Solid Central Hubs: Mounting hubs are precision-bored from solid alloy bar stock to match central shaft diameters with exact tolerances, preventing clean filtrate contamination.
● Laser-Guided Radius Profiling: Perimeter frames are CNC-curved to ensure perfect concentricity with the circular vessel shell, maximizing usable internal filtration area.
● High-Tension Mesh Assembly: Fine filtration screens are mechanically stretched prior to perimeter welding, preventing mesh sagging during horizontal fluid backwashing or dry cake discharge.
Frequently Asked Questions (FAQ)
Q1: How do horizontal leaf filter elements connect to the central discharge shaft?
Horizontal elements feature precision central hubs that slide directly over the vessel's hollow central shaft. Each hub contains internal O-ring grooves or machined compression shoulders that seal against the shaft ports, allowing clean filtrate from the leaf interior to discharge directly into the shaft.
Q2: Why is rotational and torsional rigidity important for horizontal leaf elements?
In rotating horizontal pressure leaf systems, the entire stack of leaves turns during cake discharge or washing cycles. Substandard leaves with weak outer frames can twist or deform under the resistance of heavy wet cake, causing perimeter seam splitting.
Q3: Are these elements suitable for both wet sluice and dry cake discharge models?
Yes. Our horizontal leaf elements are engineered for both dry-discharge vibratory systems and wet-discharge sluicing systems, featuring calendered smooth mesh faces that facilitate effortless cake removal in both modes.
