water well screen filter stainless steel Johnson screen Wedge wire screen
KEY DESIGN FEATURES OF WATER WELL SCREEN
V-shaped wire creating, two point particle contact preventing plugging.
Inwardly opening slots (in-flow) preventing sand particles from remaining lodged in screen.
The V-shaped wire enhances well efficiency, ensures consistent pumping and long well life.
The continuous slot wedge wire offers higher open area than any other type of screens used for water well applications, such as slotted pipe, punched pipe, louver screens.
Wedge wires for each application are selected to maximize open area, resulting in the lowest possible cost for water extraction.
Available sizes from 1" (25 mm) to 22" (560 mm)
Water well screens designed to suit well depth
Available in slots sizes from 0.15 mm to 3 mm
Length up to 6 metres available
Materials: LCG (Low Carbon Galvanised) / SS304 / S316L / SS316 / SS316L - or as required to meet Customer requirements.
End fittings - to suit Customer requirements
Continuous wire wrap screen:
Wire wrapped screens were already developed and in use in the U.S. about 90 years ago. This design makes it possible to adjust the slot width with minimum tolerances to the characteristic grain-size distribution curve of the respective aquifer and manufacture the slots in such a way that an optimal sand removal from the adjoining natural rock is possible.
Advantages
In-house manufacturing
Short delivery times
Manufacturing in compliant to DIN 4935
The wire wrapped screen provides optimal conditions for the well development (pistoning, pumping, jetting).The kinetic energy of the flowing water is increased by the nozzle of the conical slots. The wire wrapped screen, with its inward expanding slots, is particularly suitable for the inflow of water laden with small particles. Thus clogging is avoided.
