Johnson screens groundwater and wells are manufactured with V-shaped profile wire, spirally around a cage of support rods. Each intersecting point of these wires is welded. The pitch of winding provides different spaces between two adjacent turns of wire. This space gives passage for water to enter. The continuous slot openings form the larger opening area.
The Johnson screens groundwater and wells could reduce energy consumption and increase water flow. Besides, it is well-known because it can reduce erosion of entry surfaces and increase okay service life. Moreover, it allows a uniform and efficient well development and reduces potential pump damage and subsequent maintenance costs.
