FIELD: transportation.

SUBSTANCE: group of inventions relates to pumping systems of fluid medium and to methods of controlling such pumping. System comprises pump with controlled frequency of rotation and / or controlled torque for pumping fluid medium, at least one proportional control valve assembly, an actuator actuated by a fluid for controlling a load, and a control device which sets the rpm and / or torque of the pump and the position of at least one unit of the proportional control valve. Pump comprises at least one drive apparatus, supplying fluid medium to actuator, which is cylinder with drive from fluid medium, engine driven by fluid medium or other type actuator with fluid medium drive, which controls load. Each of the drive devices comprises a primary drive and a fluid transfer assembly. Fluid transfer unit is driven from primary drive so that fluid moves from inlet to pump outlet.

EFFECT: group of inventions is aimed at providing fast and accurate flow control fluid medium and / or pressure.
