Continuous slot wedge-wire screens for water wells

From DN100 to DN600

 

 

Screens are produced wrapping in continuous wire, with triangular shape, on round directress.Every intersection is resistance welding (RW).

Going through all the various combination of wire's section,number of directress and step is possible to produce screens for many different application fitting perfectly every project.

 

 

 

 

 

 

Features

V-wire screens are characterized by a large filtering surface that gives very high performance in passage of water even in presence of low speed water.

This allows to optimize the well production:

-Minimun hydraulic resistance

-Reduced encrustation

-Less impurity (sand) that might damage the pump

-Fast and complete perforation fluid removal

 

Material

The product is made in high quality Stainless Steel to resist to pressure and stresses during installation or to corrosion
