What is V-WIRE JACKETED STRAINER ? 

V-Wire screens are fabricated in pipe form from wires.  
A V-shaped profile wire is spirally wound around a cage of longitudinal support rods. Each intersecting point of these wires is fusion welded.  The pitch  of winding different spacing two
adjacent turns of wire. This space becomes passage for water to enter.  The entire manufacturing process is done in fully computer  controlled special machines. The Jacket made of this screen is mounted over the punched / slotted length of a G.I. pipe.  The pipe gives the strength required in hand boring and has large
punched  holes for large open area and the screen  jacket has fine slot opening for sand filtration.

    

THE SAILENT FEATURES :-

*    Continuous Slots :- The special design gives continuous slot opening across the periphery 
     and length of screen.
*    Non Clogging Slots  :- V-Shape wire which gives inwardly widening V-shape slots.  
     This shape does not give space for any sand particle to get stuck inside the slot and hence 
     these screens  are NON CLOGGING. Hence, the efficiency of tube well is not reduced 
     over no. of years due to clogging.
*    Very  Large % Open Area :- This design gives continuous slot and hence the % open area for 
     water to enter is more than 2 times that of conventional slotted pipes of same size and
     slot opening.  This allows more water to enter at much lesser frictional head loss and the 
     efficiency of  tube well is improved  appreciably.
*    Better Sand Filtration :- Due to specialized manufacturing process,  wide range of slot opening is 
     available down to 0.15 mm to allow proper slot selection depending upon the size of sand
     in particular area.  This gives better sand control and reduced pump maintenance
     and longer tube well life.
*    Energy Saving   :- Due to reduced frictional head losses and increased discharge, 
      the pump load reduces the power required to pump same quantity of water.  
     Power saving of  around 20-25% is observed.
