The offered turbo-pump is shown in fig.1. It consists of guide apparatus (1) fixed in stator and shaft (2) supported in bearings. Said shaft is provided with two blading sets, e.g., of propeller-type, and blade rim (4) of pump, e.g., with centrifugal rim. Every blading set is provided with its own water suction pipe (6) in turbine section and is provided with spiral case in pump section. Direct joint of turbine with pump's rotor decreases hydraulic and mechanical losses of power, as well as mass and specific metal content, likewise it increases pump efficiency and operate reliability. The lay-out diagram of the offered hydraulic unit is shown in fig.2 where the following designations are used: 9 -turbine-wheel of blade-type, 10 - water guide apparatus, 11 - rolling element bearing, 12 - hollow drive shaft, 13 - bearing unit, 14 - belt pulley of wedge-like belt, 15 - housing, 17 and 18 - bearings, 19 - control bar.
