FIELD: liquid separation.
SUBSTANCE: present invention relates to double-acting liquid separation device (2) with increased pressure, a system containing double-acting liquid separation device (2) with increased pressure, a complex containing the mentioned system, as well as to the use of the mentioned device, system and complex. Double-acting liquid separation device (2) with increased pressure for a closed volume of a hydraulic circuit is made with the possibility of supplying large volumes of hydraulic fluid under high pressure to at least the first pressure transfer device (V) and second pressure transfer device (1'') and extracting from them, wherein pressure transfer devices (1', 1'') pump large volumes of fluid with particles at a pressure above 500 bar, wherein double-acting liquid separation device (2) is made with the possibility of controlling by supplying a controlled flow through at least first control fluid channel (24') and second control fluid channel (24''), while double-acting liquid separation device (2) contains: hollow cylinder case (20) with longitudinal extension, wherein cylinder case (20) contains at least the first part and the second part having the first area (a1) of perpendicular cross-section, and the third part having the second area (a2) of perpendicular cross-section, different from the first area (a1) of perpendicular cross-section, and rod (19).
EFFECT: obtaining a double-acting liquid separation device.
