FIELD: machine building.
SUBSTANCE: proposed device comprises oil feed and discharge pipelines, heater arranged at oil feed pipe and rotary pump composed of: two discs with concentric rings arranged there between, turbine wheel and adjustment device fitted on rotary pump shaft. Besides, it is equipped with air-operated axial pump communicated via pipeline with turbine wheel. The latter is composed of double-side smaller-diameter rotary pump consisting of two discs with concentric rings arranged there between communicated via oil feed pipeline with larger-diameter rotary pump composed of two discs with concentric rings arranged there between, and fitted on the same shaft.
EFFECT: decreased hydrodynamic losses, higher quality of oil cleaning.
