を特徴とする送液ポンプ装置。 A pressurized pump that sucks liquid from the outside and applies an appropriate precompression pressure to the liquid immediately before discharging the liquid, and a pressurized pump that sucks liquid from the pressurized pump and discharges it to the outside. and a metering pump configured such that when the metering pump switches from the suction process to the discharge process, the pressure inside the metering pump chamber becomes the same as the pressure outside the pump chamber, and by rotation of a cam, the pressurized pump In a device configured to suck and discharge liquid by linearly reciprocating a plunger within a room and a metering pump chamber, means for reciprocating the cam in first and second angular ranges different from each other; , means for selecting one of the first and second angular ranges, and the cam is formed so that the amount of movement of the plunger due to rotation in the first and second angular ranges is different. A liquid pump device characterized by:
