Installation Procedure

Installation Procedure - Column Pipes

• Tighten the bottom adapter on the pump with the help of strap wrench or pipe wrench. Lower the pump in the well using loop ball or MS. clamps.
• Take a column pipe and remove the protection cap from the male end Wipe both ends using a clean piece of cloth.
• Ensure that rubber gasket supplied with the pipe is properly placed in the groove on the male threads of pipe.
• In case the seal is found to be damaged, replace it with extra sealing rings supplied in each bag.
• While lowering or extracting the pump set, pipes should be clamped at "CLAMP HERE" location marked on the pipes. Rubber sheet/cushioning between pipe surface and clamp may be used to avoid scratches/damages to the pipe
• Clamp to be used with pipe for installation should be of correct size (as shown) to avoid damage to the threads.
• Use of Supreme column pipes for submersible pump in combination with Gl pipes in the same bore well/tube well is not recommended.
• Join the pipes one after the other. Tighten the pipes by strap wrench or jerk of a pipe wrench so that 50% of rubber-sealing ring on male thread end gets into the seat of belled/coupler female square threads. Use plain water or soapy water as a thread lubricant. Do not use any oil or grease on threads.
• When the pump is lowered to the desired depth, fit top adapter to the last pipe. Connect required fittings like nipple/bend to the delivery side of top adapter.
• Use Vaibhav Polymers installation tool, i.e., loop bail for lowering the pipes in the bore well while using tripod and chain pulley block instead of M.S.clamps.
• We recommend use of Vaibhav Polymers pump guard system to make your installation foolproof against falling of pump due to excessive vibrations/jerks or during pump withdrawal.

Precautions

• Do not over tighten the pipes as it may result in crushing of rubber sealing leading to leakage/pipe failure. Use new rubber seals for every reinstallation of submersible pump.
• Do not apply grease, oil or any other oily substance on the threads.
• It is advisable to use safety device such as pump protection relay to prevent dry running of pump or pump shut-o head condition.
• In bore wells with loose boulders, casing pipes are recommended for entire depth.
• In bore wells, without full casing pipes, it is advised that at the time of removal of pumps from bore wells, if the pump gets stuck due to silt/mud or stones, the bore well should be proper flushed prior to application of pulling load.
• Use of good quality reflux valves on the delivery side is recommended for preventing water hammer, upthrust and back spin in the pumping system.
