This utility model discloses a vertical high-pressure plunger pump, including a cylinder body. One-way inlet valve 1 and one-way outlet valve 1 are connected to the top two sides of the cylinder body, respectively. One-way inlet valve 2 and one-way outlet valve 2 are connected to the bottom two sides of the cylinder body, respectively. A piston body is disposed inside the cylinder body, and an oil seal is bolted to the top of the cylinder body. This utility model, by installing one-way inlet valve 1 and one-way outlet valve 1 at the top of the cylinder body, and one-way inlet valve 2 and one-way outlet valve 2 at the bottom of the cylinder body, enables the piston body to achieve two water discharges in one movement cycle. Under the same water discharge volume, the movement frequency of the piston body is reduced, thereby extending the service life of the plunger pump. By designing the plunger pump vertically, the problem of uneven wear caused by gravity during horizontal piston body movement in existing technologies can be effectively solved, further extending the service life of the plunger pump. Furthermore, it achieves the effect of no uneven wear and complete oil-water separation in vertical plunger pump operation.
