Czechia – Pumps and compressors – 9856- Náhrada havarijních čerpadel bóru 2. HVB, systém TB1 (typ 3CHG-6K-14-2, CG-50/50K-15-1)

The subject of the public procurement is the processing of project documentation, supply and subsequent implementation of the work entitled "9856 - Replacement of failed pumps of the boric acid system 2. HVB, system TB1 (type 3CHG-6K-14-2, CG-50/50K-15-1)" at JE Dukovany in the form of a higher completed supply of a set of machines and equipment and the performance of all necessarily caused and required modifications to the affected devices, structures, and systems. As part of the implementation of JMA 9856, the Supplier will replace the failed feed pumps of the boric acid solution 3,4TB20,40,60D01 of type 3CHG-6K-14-2 and type CG-50/50K-15-1 at the selected positions. This involves a total of 6 pumps. Pumps in a non-clogging design (with a magnetic coupling) and with a separate motor, air-cooled are required. The replacement includes the modification of the connecting suction and discharge pipelines, the connecting recirculation and drainage pipelines, and the modification of the mounting of the new pump according to the newly selected assembly. The manufacturer will carry out the modification of the supporting steel structures to the extent necessary for the installation of the new pumps and the modification of the existing concrete foundation. Furthermore, the replacement of the cabling from the transition cabinets to the drive and the elimination of the separate closed cooling circuit of the pumps will take place. The exact definition of the Subject of the Public Procurement and other requirements for its implementation, including information, conditions, specifications and other data are detailed in Section 3 and 4 of the Tender Documentation.
