Technical development is one of priorities for the company. Among the first in Russia JSC “Mosenergo” started a global construction and start-up of generation facilities on the basis of gas and steam circle that allow raising effectiveness and improving ecological index of production.

To provide reliability of all the company JSC “Mosenergo” and the branches separately it was decided to make the program of replacement of worn out electric motors, and supply electric motors for compensation of emergency stock.

One of the main assemblies of TPP heat circle is feeding pumps that provide non-stop supply of feed water to steam boilers of power generating station. Operation of all TPP depends of their safe reliable and economic operation.

The line of feeding pumps typeПЭandПТНwith different flow are set at branches of JSC “Mosenergo”. To compensate emergency stock the tender to supply electric motor type 4АЗМ-4000/6000УХЛ4 was announced. Specialists from JSC “EnergoFront” analyzed  specialties and experience of operation of electric motors in set with feeding pump units at the most of power stations of JSC “Mosenergo” and decided to offer electric motor produced by NPO “Elsib” JSC, being its official partner.

NPO “Elsib” JSC is a unique power machine building works in Siberia and the Far East established in 1953. Manufacturing of three main segments is focused on one production place with substantially completed loop. The main direction of production is manufacture of turbo generates, hydro generates and large power machines.

 Electric motors produced by NPO “Elsib” JSC are used in power generating industry, transportation of oil and oil products, oil extraction, oil refining, oil and chemical, coal mining, metal and other industries including explosive production. Technical level of all products is supported with new designs by well- qualified specialists of NPO “Elsib” JSC, and is increased via modernization of constructions and growing of their durability, as well as it’s proved with tests provided.
