FIELD: engines and pumps.
SUBSTANCE: proposed system comprises mixer for low-pressure fluid feed to the pump. Said drive has drive section and hydraulic section with several plungers. It comprises also the actuator to couple drive section with selected partial set of plungers. Besides, this system comprises controller to select said partial set of plungers in compliance with working delivery, working pressure and/or indicator of hydraulic section fault. Besides, said controller feeds instructions to actuator for coupling selected set of plungers with drive section.
EFFECT: fast coupling/uncoupling of hydraulic section.
