Wedge Wire Intake Screens – T Type, I Type, Drum Type & Others

A wedge wire intake screen consists of a cylindrical or flat panel made of stainless steel wires that are shaped into a V-shaped profile. These wires are welded together at precise intervals to form slots or gaps between them. The size of the slots can be customized based on specific application requirements.

These water intake screens are utilized in the intake systems of pumps, wells, and reservoirs to prevent the entry of debris that could damage equipment or disrupt operations.

Wedge wire intake screens offer several advantages over other types of screens. They have a higher open area, allowing for increased flow rates and reduced pressure drop. The V-shaped profile of the wires provides excellent mechanical strength, allowing the screen to withstand high pressures and heavy loads without deformation. The precise slot openings provide accurate particle retention, ensuring efficient filtration. Additionally, the screens are resistant to corrosion, making them suitable for use in harsh environments.
