Providing, Installation, Testing and Commissioning of Submersible Pump set having specifications 20000 GPH X 110 Mtrs head along with allied works at T/well Guest House under JMC Capex (New Works) 2026-27.

Providing, Installation, Testing and commissioning of 01 no. submersible pump set at Tube Well Guest House of specification 20000 GPH X 110Mtrs by way of fabrication and fitting of 01 Nos. U-shaped tie rod/clamp which is to be fabricated out of MS flat and to be fitted with submersible pump by fabrication and fitting of bolts and nuts which are to be welded on both sides of the clamp. The job also includes fabrication of 01 nos, expander/reducer nipples for NRV of required size which is to be fabricated out of MS pipe threaded at one end and flanged at the other end. Fitting of reducer/expander nipple at one end with flange joint and with the discharge outlet (NRV) of the submersible pump at the other end. Extraction of old sub pump set and then lowering of submersible pump column pipes one by one by fastening the nuts and bolts and insertion of rubber insertion sheet. Making connections with the panel for testing of submersible pump set on full load at site. The job also includes providing and fitting of 3.5 core 95 sq mm (40 mtr) aluminum cable from transformer to main switch/Panel including proper thimbling. Job also includes Design, fabrication, installation, testing and commissioning of LT control panel cum star delta starter for operation of 60 HP Motor at Tube Well Guest House. The panel is tell sheet enclosed dust and vermin proof fabricated supported on M5 angle of suitable size and provision for fixing it on the ground with the help of foundation bolts. Panel edges and door edges is reinforced against distortion. The panel is sturdy enough for vibration free operation and is equipped with suitable locking/sealing arrangements. The structure is provided suitable entry and exit holes for incoming and outgoing cables. The panel is given two coats of anti-rust primer and two coats of powdered coated steel grey paint and is equipped with following components. 1. Incoming Panel Box: The incoming panel box is fitted with MCCB of 250 Ampere capacity for OL, SC, EF protection having display with ON/OFF, trip indicating light, digital multifunction meter with communication port (RJ485), digital voltmeter, digital ammeter, control fuse etc. of approved make 2. Star delta starter: - The panel is fitted with a fully automatic contactor of 140 Amp-2 nos. and 110 Amp-1 no. for star delta operation, 1 no. timer for change over the supply of motor from star to delta, 2 nos, push buttons for start and stop operation of motor, 3 nos indicators, for status of starter i.e. running, tripped, by passed / in line of protection system. 1 no. MCB 10 Amps for the protection of internal control wiring. Complete accessories of approved make. Neat and clean internal control wiring is made with the flexible copper cables to complete the start delta circuit of outgoing supply. 3.Protections device: The panel is fitted with protection devices like relay, CT/PT, timer, ROM of suitable rating having inbuilt display ON/OFF, control fuse, fault analyzer with capacity to protect motor by isolating the power supply of motor de-energizing the starter/ panel from electro-mechanical faults which may otherwise damage the motor windings like phasing, under voltage, over voltage, unbalanced voltage, reverse phasing, over current/load, dry running, unbalanced current/load, earth leakage, short circuiting, locked motor, broken shaft. It also displays current of RYB phase and also line voltage of RY an YB phase and record trip counts and indicate trip status for over load, under load, single phase, unbalanced phase, earth fault, over voltage, under voltage, under voltage/reverse phasing respectively. Analyze, display and record no of operation and duration of motor running Complete accessories of reputed make. 4. Bi-metallic overload relay: - A bi-metal over load relay of suitable range is fitted with in the starter as an extra protection to protect the motor in case of failure of fault analyzer with an isolation / bye pass switch to bye pass the fault analyzer. 5. Auto operation system: - The panel is fitted with an auto operation system of comprising of 1 no. delay timer and 1 no time switch to set the time of motor running (in auto mode only). 6. Automation: The panel is to be fitted with an automation system in which the tripped motor tripped due to power failure or by the protection device, should start automatically after the resumption of power or rectification of voltage related faults. But in case of current and mechanical faults the motor should start after pressing the manual reset button thus providing complete protection as well as complete automation simultaneously. Installation: In addition to this the panel cum star delta starter is properly installed at pumping station on floor / wall as per site provision foundation bolts in ground. The bus bar / cable is fitted with the help of insulators into the panel firmly to withstand any short circuit stresses. All the internal wiring is neat and clean. Complete job including cost of material and labor charges, transportation of panel from workshop to pumping station at site of work and rebate on old panel. The job also includes testing / setting of protection panel at different loads. Complete job includes 01 no. submersible pump sets, cable, Panel, tie rods, nuts, bolts, Rubber sheet, NRV, extraction of old sub pump set and lowering of new sub pump set along with allied accessories and rebate on old parts and old cables etc.
