The invention discloses a damping type plunger pump which adopts a circular-ring-shaped linear motor drive technology. The damping type plunger pump comprises a special circular-ring-shaped plunger piston which can be driven by a coil surrounded by the special circular-ring-shaped plunger piston to rotate clockwise / anticlockwise in the circumferential direction; a water inlet chamber and a water outlet chamber are integrated, so that system problems such as vibration generated when an existing single-plunger-piston double-cylinder pump moves the plunger piston left and right are reduced; moreover, the plunger piston is embedded into a circular-arc-type drive coil, so that the plunger piston and the drive coil are supported by a copper oil-containing bearing; a water inlet chamber assembly and a water outlet chamber assembly are integrated and are arranged in a centrosymmetric mode, so that high-pressure outlet water with pulsation is mixed in the water outlet chamber or a high-pressure gas chamber is added, and therefore, pulsation of final outlet water is reduced.
