About company

R&PC "ANOD" is a company with a 25-year experience in the industrial applications market.

To provide innovative and tailor-made solutions, our team includes about 200 skilled and qualified engineers of the following divisions:

  • Design,
  • Product Technology,
  • Production,
  • Service.

We produce:

  • Mechanical seals of high reliability, durability, stability at high temperature and pressure drop.
  • Highly efficient pump units with high reliability sealing complex and the original bearing support.
  • Sliding bearings of increased bearing capacity and durability, performed in a monoblock construction.
  • Bearing-sealing units (BPU), providing an upgrade of almost any pump by foreign or domestic manufacturer, thus improving their technical parameters and operational life.
  • Support systems for mechanical seals and bearing-sealing units (BPU).
  • Valves of new design with high hermetic and lifetime characteristics.

Products are certified according to TR CU 010/2011, TR CU 012/2011.

The high technical level of products is ensured by the use of inventions, patents and "know-how" of employees, allowing substitution of equipment for any industry.

Mechanical seal for stern tube device of a propeller shaft

One of the new products produced and launched by ANOD last years is designing of a mechanical seal for stern tube device of a propeller shaft 115 mm at the frequency of the propeller shaft speed 1400 rev/min.
The particularities of exploitation of the mechanical seal are the presence of large radial and angular shaft displacements and the necessity of providing dismantling and repair of mechanical seals without leakage of outside water on the shaft during the repair. On this vessel, angular displacement appears as a result of vertical displacements of the engine, installed on elastic supports.
Finally they designed the construction of a mechanical seal which provides pressurization at radial displacements of the shaft up to 6 mm in the place of installation of the mechanical seal. The pressurization on the shaft during dismantling of the mechanical seal for repair is performed with an original construction of a parking seal in the form of an inflatable pneumostop. To increase resources for wear from abrasive mixture they use friction pairs of silicon carbide, repairing a mechanical seal after grinding it’s possible to use the friction pairs again.
Successful exploitation of mechanical seals on vessels showed good reparability and reliability in comparison with foreign analogues. Created by ANOD the system of design of mechanical seals and plain bearings has successfully been used for more than 20 years and allows to produce constructions of increased durability exploited for petrochemical plants, energy companies, oil and gas transport companies.
