Column Pipe Adapter

column pipe for borewell

Sudarshan Column Pipe Adopter for connection of submersible pump to uPVC column pipes, one bottom and one top adopter is required since submersible pumps have ‘V’ Threads and Sudarshan column pipes are manufactured with square threads. Bottom Adopter’s ‘V’ thread is connected with that of pump, and its square thread is connected with that of pipe.

Column Pipe Adopters are available in stainless steel and mild steel. We advise bottom adopter material should be stainless steel as it is to be inside water and top adopter may be stainless steel or mild steel.

NOTE: Adopter’s specification for Heavy Series Pipes is different from that for other classes of pipes.

  • Available from 1″ to 6″ sizes
  • Regular (Standard) and Heavy (Long) Series
  • Top Adopter is available in SS304, Cast Iron (Cl) & Mild Steel (MS)
  • Bottom Adopter, Reducer, Expander available in SS304 & Cast Iron (Cl)
  • Pump Guard Flanges & Rods available in SS304

  1. First connect the male end of M.S/ S.S bottom adaptor to submersible borehole pump using chain wrench.
  2. Join the Sudarshan Pump Guard to the bottom Adaptor along with M.S/ S.S flange rod.
  3. Now connect the first pipe to the female end of the pump guard.
  4. Before connecting the pipes pump guard, clean the threads with clean water and check for proper fitment of rubber sealing.
  5. While fitting of pipe hold the coupler by hand / wrench.
  6. Tighten the pipes by hand, until the rubber sealing in the pipe end completely enters the coupling. However, for better grip strap wrench can be used to hold / tighten the pipes.
  7. At the time of lowering the pump into borehole, the clamp must be fastened only to the portion marked just below the coupler.
  8. Then all the other Sudarshan Column pipes can be connected the same way. Pipe wrenches should not be used for support.
  9. Once the top column pipe reaches the ground level, connect the top adaptor with male end connection.
  10. Finally, from the ground level regular plumbing accessories can be used to transfer water to the required delivery point.
  11. *Do not use oil on square threads of Sudarshan Column Pipes. Clean the threads with normal water and check the proper fitment of rubber sealing element.

Full casing of bore well is recommended for long life of bore and pump. It prevents the pump from getting stuck due to loose boulders, stones, soil and silt. It also reduces chances of accident due to protruding stones and boulders at the time of removing the pump and pipe.

Avoid Dry Run of Pump

The dry run of submersible pump generates hot air which can damage/ deform the first Column Pipe connected with the pump. To avoid this:

  • Use timer switch to turn on or off the pump automatically as per the pre-set time, determined after assessing the bore yield.
  • Use of 3 metres S.S Pipe between pump and SEPL uPVC Column Pipe will help dissipate the heat, preventing any damage or deformation.

Prevention of Water Hammer

At the time of pump stoppage, water recedes/falls at tremendous speed from a height. Especially in deep bore wells of about 500 ft & above, this creates enormous pressure and load on the pump and bottom most pipe called as water hammering. For such deep bore wells, it is recommended to make a 3mm hole in the pump NRV to protect the pump and pipe from water hammering.
