Wedge Wire Lateral Assemblies: The Keystone to Precision Filtration
Our Wedge Wire Screen Lateral Assemblies are expertly crafted as indispensable vessel internals. Featuring a robust hub steel pipe and precisely engineered screen laterals, these assemblies excel at efficiently collecting or distributing liquid and gas, while ensuring the medium remains securely contained.
Renowned as Under Draining Filtering, our Wedge Wire Screen Lateral Assemblies serve as versatile solutions for water distribution and medium collection, ensuring unparalleled performance.
Tailor-made to perfection, our wedge wire screen laterals assemblies can be customized to match the specific specifications of Vessel/Filter size, flange dimensions, flowrate, and medium size requirements.
Ingenious design options for the middle row device of our wedge wire screen laterals include versatile shapes such as ordinary radial, fishbone, and T-type configurations. Both the lateral branch pipes and the hub master pipe are meticulously designed and produced to align with customer specifications.
Wedge wire screen laterals assemblies are the preferred choice across a spectrum of applications, including ion exchange, clay and sand filtration, carbon towers, and power plant water systems, delivering formidable performance and reliability.

Hub and Header Lateral Assembly
Our innovative wedge wire screen lateral assemblies are thoughtfully categorized into hub lateral assembly and header lateral assembly, determined by their strategic installation position and critical function within the tank.
- The hub lateral assembly, expertly positioned at either the top or bottom of the tank, plays a vital role in the efficient distribution and collection of liquids at the equipment outlet.
- In contrast, the header lateral assembly is strategically placed in the tank's middle section. Its purpose is to ensure the even spread and discharge of liquids, effectively preventing any media from escaping.
- Our hub and header lateral assemblies boast various innovative shapes, including radial type and fish spike type. We offer bespoke designs and manufacturing for wedge wire lateral assemblies, tailored to customer's specifications for main pipe diameters and lateral quantities.
Hub Radial Lateral Assembly
The hub radial lateral assembly features a central hub coupled with multiple screen laterals, ideally installed at the top or bottom of the vessel. It functions as a hub-lateral distributor for optimal liquid distribution at the top, and as a hub-lateral collector at the bottom for effective liquid collection. In radial flow equipment like centrifuges, it ensures uniform distribution or concentrated collection of liquids within the equipment. Available in configurations such as 4 laterals (cross laterals), 6, 8, 16 laterals, with options for one or two-layer screen laterals.
Hub Fish Spike Lateral Assembly
The uniquely structured hub fish spike lateral assembly stands apart from the hub radial lateral assembly. It is primarily utilized for effective liquid distribution at the top and efficient liquid collection at the bottom of large tanks.
Header Lateral Assembly
Crafted with precision, the header lateral assembly comprises a central header flanked by several screen laterals. It resides in the tank's middle section to guarantee the even distribution or collection of liquids, either within or at the vessel's outlet. Designed to adapt seamlessly to varying process conditions, it promises exceptional distribution efficiency.
