Sub. Main Pump specification - HFTFIn the HFTF facility two pumps connected in parallel, provide the required flow at the operatingpressure. A booster pump is also provided at the inlet of the main pumps. The booster pump is providedwith a flow rate of 140 m3/h at 3 bar pressure. The Main pump generate the required flow and_pressurefor the smooth operation of the loop during testing. The maximum pressure and flow rate requirements for HFCV, for flow capacity testsas per theprocedures are 62.9 bar@ 22m3/hand 110m3/h @ 58.7 bar(for both valves together). The permanentpressure drop due to all components other than HFCV, CVl & CV2 at rated flow is less than2 bar (ref:Design Basis Report-High Pressure High Flow Test Facility HFTF) Rev 14.). The control valves CV2 andCVl are provided to create the required pressure at the upstream of the HFCV under test.Considering these factors, two identical pumps having a delivery pressure of 70bar@60m3/h shouldsuffice the test requirement. As per the specification approved by BARC, the pressure and flowrequirements of the pumps are 75 bar@ 70m3/hTwo separate attempts were made to procure pumps with the above specification (75 bar.@ 70m3/h).Unfortunately only one party has quoted with the above specification with all wetted parts in Stainlesssteel with a delivery time of 7 months as these pumps are not in their standard range.It is requested that the operating parameters of the pumps may be modified as 60m3/h @ 75 barinstead of 7Sm 3/h @75 bar. All these pumps have a delivery period exceeding 5 months as they are notstandard models.The HQ curve of the second party quoted for both the above tenders is also attached here with. Thispump can develop 60m3/h @ 75 bar. This can develop 70m3h @ 72 bar (please refer attached pumpcurve) and will operate at best efficiency point BEP). Also the Booster pump is capable of delivering 3bar line pressure. Thus testing of an HFCV can be done with a single pump itself as anticipated in theMOU.It is requested that you may consider the above case and intimate the modification in the pumpspecification so as to proceed with tendering with modified specifications.~r.
