12-13 March 2025 at Transneft Oil Pumps JSC production site in Chelyabinsk comprehensive acceptance tests attended by Caspian Pipeline Consortium experts and representatives were successfully completed of a prototype of the new model of electric pump unit ANM 4500-650.
Test outcome established the pump unit’s actual characteristics meet the manufacturer's production specifications, terms of reference for development of design documentation and manufacturing of mainline pump unit (MPU) prototype, and requirements of GOST 32601-2022.
The electric pump unit ANM 4500-650 comprises the pump NM 4500-650 and asynchronous electric motor AN860A-8300 fitted on a common skid, and includes auxiliary piping used by systems of lubricating oil, leak collection, hazardous vapor relief, pump drainage, product supply to pump mechanical seals, instrumentation, and temperature and vibration monitoring.
The pump and 8.3 MW electric motor prototypes were developed within the national import substitution program under CPC-R order for execution of the Program to replace gas turbine-driven mainline pumps with electric motor-driven MPU. Despite the complexity of creating a pump and electric motor that are atypical for domestic manufacturing industry all tasks were completed on time and took just 12 months.
Manufacturing of the pump and electric motor prototypes and their preliminary tests were successfully completed in February 2025 at Transneft Oil Pumps JSC and Russian Electric Motors JSC production sites with active support from PAO Transneft, a state-owned CPC-R shareholder.
As part of MPU prototype manufacturing CPC-R and Ural Dynamic Machines LLC (managing company to TOP JSC and REM JSC) teams collectively performed hydrodynamic and strength calculations, developed and approved design documents, built and tested a scale model of the prototype pump's flow section that demonstrated conformance to all rated Q-H characteristics.
For use in comprehensive acceptance tests of the mainline pump unit CPC-R purchased and delivered to TOP JSC production site electric motor purging and cooling ventilation unit and FC power equipment. Assembly was then fast-tracked of this equipment into an integrated testing system that allows a full range of all types of tests to be performed on pump units with capacity up to 15 000 m3/h.
In April-May 2025 based on the range of tests completed the pump unit will be certified for compliance with manufacturer’s production specifications, GOST 32601-2022 and will be cleared for mass production as one in a series of typical pumps.
For information:
CPC Pipeline System is one of the largest projects in CIS energy sector. The length of the Tengiz-Novorossiysk pipeline is 1,511 km. This route transports over two-thirds of all Kazakhstan export oil, and crude from Russian oil fields, including those in the Caspian Region. CPC Marine Terminal features three Single Point Moorings (SPM) that enable safe tanker loading at significant distance offshore.
