Agriculture uPVC Column Pipes

• Square threads gives better joint strength
• Light weight
• Cost effective and easy to handle
• 100% leak proof joints
• Long life
• Strong and durable
• Smooth internal surface
• Lead Free Column Pipe

The column pipes must be selected from the types available, so that the pump delivery pressure does not exceed the permissible hydrostatic pressure. In the column, for every 10m above the pump, there is a pressure drop of 1 kg/cma. If the pump delivery pressure is high, two different class pipes Of the same size can be used, instead of using same type of pipes alone for the entire depth, to make it cost effective. Heavy type pipes can be used upto required length starting from pump and medium plus / standard type pipes can be used for the remaining length.

An illustration is given below. As per above illustration 40m of Heavy class pipes must be used starting from the pump, even for the lower depth instaIlations since the pump del ivery pressure is 24kg / cm2 While selecting the pipe it must ensured that the total load is very well within the recommended ultimate breaking load.

• First connect the male end of the bottom adaptor (C. L/ S .S) firmly to the pump discharge housing using a pipe wrench and first pipe can be connected to the female end.
• Before connecting clean both the ends of the pipes with clean water and check rubber seal ring for any damage.
• The pipe can be tightened by hand itself but, while tightening water has to be poured on pipe threads for lubrication. Anyhow for better grip strap wrench can be used to tighten / hold the pipes.
• Tighten the pipes by hand, until the rubber seal ring in the pipe end completely enters in to the coupling. Submersible pump cable need to be tied in regular intervals along with the column pipes, for securing the cable from getting damaged.
• At the time Of lowering the pump into borehole the C-clamp must be fastened only to the pipe portion marked as “CLAMP HERE”. Then all other pipes can also be connected in the same way. Pipe wrench should not be used on the pipe for support.
• Once the top column pipe reaches the ground level, connect the top adaptor with male end connection. Finally from the ground level regular plumbing accessories can be used to transfer water to required delivery point.
