In a plunger pump sealing device that includes an elastic sealing member in the gap, there is provided a sealing device in the gap between the suction valve body and the cylinder wall at a predetermined interval in order to form a hollow chamber in the gap between the suction valve body and the cylinder wall. A plunger pump characterized in that it is equipped with a highly elastic sealing member and a pressure introducing means that penetrates the cylinder wall and seals a static constant pressure higher than the maximum pressure in the pressure chamber into the hollow chamber. sealing device.
