Brief description of the project

New technology is proposed as to the arrangement of a multistage pump for raising its wear resistance. The proposed technology makes it possible to simplify multistage pump design thanks to new arrangement of shaft centrifugal wheels, to provide for moving abrasive liquid inside those wheels through the spaces without any cross-flow, to secure shaft rigidity and to increase wear resistance and life of the pump


The multistage pump is designed to feed the evacuated liquid under pressure, particularly for feeding it to the surface out of boreholes from great depths

Field of application

Oil production

Volume of effective demand

The proposed multistage pump will be of great demand on the market both in the Russian Federation and abroad.

Form of intellectual property protection

Application 200107510 of March,14, 2006 is made for patent acquiring.

Present stage of development

The authors have working drawings of the multistage pump available

Supposed form of cooperation

Cooperation may be realised by legalisation and selling of licensed know-how contract
