    摘要: A plunger pump, includes: a plunger pump unit including a pump chamber and a plunger for pressing a hydraulic fluid in the pump chamber to perform a discharging operation of the hydraulic fluid; a motor; and a cam portion driven by the motor to rotate and press the plunger. The cam portion has at least two discharge regions for pressing the plunger and a suction region formed between the discharge region. The plunger performs the discharging operation two times or more by one rotation of the cam portion.
