The Pump bowl should be of close grained cast iron with renewable wearing rings of bronze material .The Pump shaft shall be of stainless steel , guided with stainless steel distance sleeves /shaft protection sleeves provided with each bowl above and below the be stainless steel impeller. The Casing wearing rings shall be of bronze material . The Coupling shall be of Mesh type rigid sleeve of stainless steel , non-slipping type with matching groove and cotter arrangement to suite keyway provided. The Suction case shall be of close grained cast iron material . The motor should be three phase AC supply having nominal speed of 2900 RPM, 380 Volts + 15% of frequency 50 Hz + 3%.The motor should be totally enclosed squirrel cage induction type, water cooled and sealed against outside water being pumped. The windings shall be wet type water lubricated and provided with metal tilting thrust pad designed to take up all untoward load to most unfavorable running conditions. The acceptable makes of Submersible Pump Set are of reputed make viz. KSB/Kirloskar. The job involves fabrication of adopter Nipple/reducer nipple approx 0.5 mtr long fabricated out of MS Pipe, of which bottom end diameter is to be reduced to the delivery portion to the Sub. Pump and other end of the adopter nipple is welded with MS flange of required size fabricated out of MS Plate for fixing with the column pipe.2 No nuts of required size are to be welded on opposite size of the proper piece so that clamping bolt of the tie rod can passed through it. Fabrication of the tie rod clamping arrangement for clamping the pump and motor to the upper adopter nipple, fabricated out of 40mmx6mm MS Plate as per required size at site. The upper ends of these flat strips should be welded with full threaded bolt 12mm dia. and 10 cm long. These bolts are to be passed through the nuts welded on the adopter nipple piece, tightening of the 12 mm double nuts on both sides including cost of material and labour charges. The Job includes coupling of pump and motor properly checking of movement of the pump, tightening of the adopter nipple to the delivery side of the pump, tightening of tie rod and testing of the pumpset in the testing pit at workshop. Shifting of the submersible pump to work site. Extraction of the old submersible pump by using requisite tools/ tackles and manual labour etc. Job involves dismantling of electrical connections from outgoing terminals of LT control panel then extraction of submersible pumps along with column pipes. Shifting of column pipes- 08 nos. 150 mm dia to workshop with the help of mechanical transport. Cutting of old and damaged flanges, Fabrication of the new flanges as per size and thickness by cutting as per original size, drilling of holes and welding to both ends of column pipes in proper alignment by 16 no. of flanges. Job includes painting of column pipes. Providing/ fitting of 25 sq mm 3-core flexible submersible cable (preferable make Kei/ Finolex/ Havells/Polycab) – 50 DMT in place of old damaged cable. Making connections of motor's leads with new submersible cable by making proper water proof joints. Making connections of existing submersible cable with new submersible pump by making proper water proof joints. Lowering of submersible pumpset into the Tube well along with the column pipes by using special tools and tackles. The job also includes providing and fitting of 50 sq mm flexible single core copper cable -16 mtr. in length from outgoing terminal of the main switch to the voltage stabilizer and from voltage stabilizer to panel with proper thimbling /crimpling and insulation material. Making all electrical connections of Submersible PumpSet with LT control panel by proper thimbling and crimpling all cable ends and then testing and checking for specified amperage on full load. Complete job includes the cost of material, labour charges, taxes, other unforeseen material, transportation charges including manual carriage, hire charges of tools and tackles required for execution of job at site. Complete job. Re-erection of 100 KVA Electric substation of Tube well. Dismantling of all the MS nut/bolts. Stacking of all the dismantled material i.e MS strips/ channels/ insulators/HT Knife set Jumpers/HT fuse assembly/ LT fuse Assembly etc. from the poles inside the tube well room. Mounting/providing/fitting including replacement of worn out/damaged items by new material including MS strips/ channels/ insulators/HT Knife set Jumpers/HT fuse assembly/ LT fuse Assembly etc. by using requite tools and tackles and proper expertise of skilled labour. Making all HT /LT connections and then testing the transformer on full load. Complete job includes cost of material, labour charges, hire charges of crane, transportation charges, taxes and any other unforeseen material required at site
