FIELD: oil and gas industry.
SUBSTANCE: group of inventions relates to the oil and gas industry, in particular, to the soil hydraulic fracturing equipment and technologies. Pressure exchange system includes rotary isobaric pressure exchanger (IPX) configured to exchange pressure between the first fluid and the second fluid, as well as coupled to the IPX and configured to actuate the IPX motion system. Motion system comprises electric motor, on the IPX rotor having first permanent magnets or first electromagnets configured to interact with the second permanent magnets or second electromagnets. Second electromagnets are connected to passing through the rotor shaft.
EFFECT: inventions allow to inject the fracturing fluid into the well, preventing or limiting the high pressure pumps wear.
