FIELD: engines and pumps.
SUBSTANCE: invention relates to pump system to be used in remote regions for underwater extraction of hydrocarbons. Claimed system comprises high-pressure fluid source, reciprocating or oscillating pump driven by fluid and the valve to convert fluid constant pressure into oscillating pressure for pump actuation. Said converting valve is built in the discharge line, between high-pressure fluid source and the pump. High-pressure fluid in pipeline actuating the pump represents hydrocarbons extracted from the well. Note here that the compressor running on extracted gas makes the actuating fluid.
EFFECT: simplified design, expanded operating performances, self-contained system.
