PURPOSE: A magnet type hydraulic pump is provided to minimize driving power of the hydraulic pump by removing the power consumption due to the link between a driving part and plungers by linking the driving part and the plungers with magnetic force. CONSTITUTION: A magnet type hydraulic pump includes a magnetic pump assembly including a wheel(1) attached with two sets of magnets having different poles, a pump assembly incorporated with magnetic plungers(15,16) in an axial direction of the wheel, and formed with a plurality set of suction and discharge holes(11a,12a) in a peripheral direction for the axial movement of the magnetic plungers, a through hole(18) drilled in the core direction for connecting the respective holes, a plug(17) provided around the through hole for sealing the through hole, and a sealing cover(4) for protecting the pump assembly. The suction and discharge holes are respectively provided with coaxial circle shaped suction and discharge grooves(11,12) around the holes for the supply of working oil and extruding oil, and supply and discharge holes(6a,7a) at upper and lower parts respectively. Seals(8) are provided to the holes and the grooves for preventing oil leakage, and a valve rod(13) is provided to the discharge hole for preventing counterflow of the pressing oil, wherein the pressing oil circulates by the reciprocation of the magnetic plungers due to the suction and repulsive force of the magnets generated by the rotation of the wheel.
