are used in hydraulic systems of metal-cutting machines and other machines. Provide a change in the supply of mineral oil from nominal to zero when it reaches a pressure system equal to the pressure of the valve settings. The setting of the valve of the pressure regulator is mechanical. A mechanical change in the working volume is provided to reduce the value of the nominal feed. Pumps are produced in a pressure of 6.3 MPa and 16 MPa. Rotation frequency - 1450 rpm, rotation direction - right (clockwise from the drive side).
