DKI

Limited Liability Company

The company OOO DKI is one of the key players in its segment in the turbomachinery equipment market. This goal was not achieved overnight, but was the result of more than twenty years of painstaking and united work of a team of like-minded people charged with success.

In our still short history, we have come a long way from an assembly shop to a formed manufacturing enterprise that strives to work on the basis of the highest standards of quality and organization of the production process.

At a strategically important moment for the company and the industry, we were able to switch to manufacturing products without the use of foreign components and maintain a leading position in the Russian market.

Despite the achieved results, the company is at the beginning of the path to developing and launching its own innovative products, expanding the range of manufactured products, and improving the production environment.

Basic lines of the Company's activity are as follows:

  • Production and supply of dry gas seals (DGS) and DGS control panels for gas, oil refining and chemical enterprises
  • Retrofitting compressor equipment involving installation of DKI DGS
  • Technical maintenance and refurbishment of compressor equipment
  • Servicing and refurbishment of supplied equipment
  • Manufacture and supply of membrane couplings for a vast scope of application
  • Manufacture and supply of filtration systems
