a.) Design, Manufacture, assembling, factory testing, supply, installation, testing and Commissioning [at LIS Rajal of new raw water (cold river water) complete replacement of bowl assembly] of new bowl assembly for already installed 20 cusecs discharge 40 m Head VT pump (700 T1A6 model of Jyoti make) at LIS Rajal coupled with 3-phase 6.6kV, 50Hz, 986 rpm (ACW), slip ring, vertical solid shaft, 400HP HT induction motor. The Bowl assembly shall be suitable for following parameters of units installed/site conditions:- PUMP: VT pump of capacity (Q) 20 cusecs x 40 m head (H) with two stages having speed of 986 RPM. The pump is to be operated in open sump in parallel with other pump of same capacity with minimum submergence of 2.50 mtrs. Forced external clear water lubricated pump at the pressure of 5.0 kg/sq. cm. The bowl assembly run on 300 kW/400HP motor. Column Pipe assembly:- Size 500mm x 200mm x 70mm dia with discharge outlet size of 500mm dia. PRIME MOVER/DRIVER:- Slip ring type Solid shaft, Three phase 400 H.P, 6.6 KV, 50 Hz AC electric induction motor of nominal speed 986 RPM. TYPE OF DUTY WATER: cold water, silt laden, raw water (fresh raw water) Apart from above described parameters other desired specifications affecting the bowl assembly shall satisfy/coincide the requirement as per installed complete VT pumping unit of Jyoti make model 700 T1A6 and other site conditions. The job includes assembling of bowl assembly with already existing column pipe assembly (shaft enclosing tube and line shaft), forced water lubrication system, discharge head and coupling with electric Prime- mover & providing / fitting in position of nuts/ bolts of sorts as per actual specifications. Testing: Obtaining of expected field performance curve/ in lab/ shop testing and lab/shop testing at reduced speed and stages shall be according to IS 5120 with revision, if any through CEIL/RITES. Field test shall be carried under actual site conditions to check/ test at specified speed, discharge, delivery head, net pump effective head, and other connected parameter over a specified period with regular observations. The job includes cost of component, labour, skilled and semi-skilled carriage to & fro transportation, loading unloading, handling, Storage / stacking, connected tools/ tackles(crane,welding set etc), testing, commissioning and required servicing over the warranty period. (Complete job as per parameters/technical specifications and conditions mentioned in SBD).
