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 gives different spacing between 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. One ends of screen is closed by a flat screen of same slot opening and other end is fitted with a threaded ring and end cap for resting on the pump. The subnersible pump with motor is to be fitted inside this jacket.Thus it ensures that water reaching pump with a threaded ring and end cap for resting on the pump. The subnersible pump with motor is to be fitted inside this jacket. Thus it ensures that water reaching the pump is filtered through screen and clear water coloumn is available to pump. This reduces wear of pump impellers due to sand in an existing tubewell.
