The utility model provides a duplex plunger device which comprises a cylinder body, a plunger piston and a plunger piston rod. The pressurizing mechanism comprises a plunger and an energy storage component; the plunger is constructed to reciprocate in the cylinder body under the action of external force so as to provide pressure for the pressurizing cavity. The energy storage component is configured to absorb energy of the plunger when the plunger moves from the pressurizing position to the initial position and release energy to the plunger when the plunger moves from the initial position to the pressurizing position. The energy storage component collects and stores energy which is originally wasted in the plunger pressurization process and releases the energy in the process that the plunger does work on the pressurization cavity for pressurization, the output power of the plunger is fully utilized, the working efficiency is effectively improved, and resources consumed by movement of the plunger are saved.
