Hydraulic assembly, particularly pump assembly for use in reverse osmosis system, has hydraulic unit, particularly pressure converter, which has rotor, and another hydraulic unit, particularly booster pump, which has rotor and housing

摘要

The hydraulic assembly has a hydraulic unit, particularly a pressure converter (2), which has a rotor (9), and another hydraulic unit, particularly a booster pump (7), which has a rotor (11) and a housing. A drive shaft (10) connects the two rotors. A sealing element is rotatably arranged on the drive shaft and is impinged with pressure in the interior of the housing. The pressure presses the sealing element with an axial front side on a contact surface in the housing section (15).
