Pumping and Thermal-Mechanical Equipment for NPPs and Gas-Petrochemical Industry

Afrikantov OKBM JSC has many years of experience in creating the following types of nuclear power equipment:

  • circulation pumps of various types and purposes, gas blowers, compressors;

  • heat-exchange equipment and steam generators of increased efficiency for various coolants (water, sodium, gas);

  • leak-tight control, safety and shut-off valves used in the power industry;

  • reactor control and protection system mechanisms;

  • vessel structures, pressure vessels;

  • instrumentation and control systems for power installations;

  • sensors measuring physical quantities and process parameters in nuclear power installations;

The equipment created in Afrikantov OKBM JSC has high safety and reliability indicators with minimum operating costs. The main equipment of nuclear icebreaker power plants (main circulation pumps, primary circuit valves, reactor control and protection system mechanisms, steam generators) with an assigned lifetime of 60 thousand hours has an operating time of over 180 thousand hours and continues to operate.

Afrikantov OKBM JSC ensured the delivery of all BN-800 reactor equipment, a significant part of which was manufactured by the Company itself. The Company is a complete supplier of equipment for ship reactor plants for the Navy and the first floating nuclear power plant—KLT-40S. The Company supplies thermal-mechanical equipment to NPPs operating and under construction in Russia and abroad.

In 2002–2008, Afrikantov OKBM JSC manufactured and delivered a set of equipment for the CEFR Chinese experimental fast reactor.

More than 350 units of pump equipment were supplied to the Tianwan NPP (China), the Kudankulam NPP, the Baltic NPP, the Leningrad NPP-2, and the Belarusian NPP.

The booster pumps were supplied to the Balakovo, Volgodonks, Kalinin, and Novovoronezh NPPs. Upgraded pumps for emergency and scheduled cooldown and ventilation equipment were supplied to Unit 2 of the Rostov NPP and Unit 1 of the Balakovo NPP. New-generation pumps were supplied to Units 3 and 4 of the Rostov NPP: auxiliary feed, emergency feed, emergency and scheduled cooldown, spray pumps.

Afrikantov OKBM JSC performs a great amount of activities to implement programs for creating the unified pumping and ventilating equipment for NPPs, for modernization of the thermal and mechanical equipment of operating units of Russia’s NPPs, and for creating the import-substituting equipment for NPPs under construction.

Using the experience gained in the nuclear industry, Afrikantov OKBM JSC successfully meets the objectives to adapt its conventional products to the needs of various sectors of the national economy, including oil and gas and chemical complexes.

For this purpose, the Company developed a parametric lineup of canned-motor pumps for various explosive and fire-hazardous media (hydrocarbons, liquefied gases, gasoline, phenol, oils, etc.).

In 2019, two ENK 268/205 cryogenic electric pumps and one ENK 40/400 electric pump were delivered for the fourth line of the Arctic Cascade (Yamal LNG) LNG production plant.


ENK 40/400                                                                      ENK 268/205      ENK  1750/188                               

The proposed pumps ensure high operating performance: the assigned lifetime without any disassembly or repairs is 40,000 hours, the service life is over 20 years.

In November, 2020, the first Russian-made large-capacity ENK 1750/188 cryogenic pump developed and manufactured by Afrikantov OKBM JSC passed the pilot testing conducted at the tank battery of the Yamal LNG production plant. Currently, the pump pilot sample continues to be in operation, which demonstrates further successful development of Russian technologies in the LNG industry.

A number of sizes of high pressure fittings have been developed. The valves produced by OKBM Afrikantov are successfully used as part of chemical plants that produce carbamide.
