The invention provides a pressure difference type energy recycling pump which comprises a piston assembly and the like; the two ends of a cylinder body cling to cylinder covers and connecting table bases separately; the cylinder body clings to O-shaped rings; the O-shaped rings are positioned in grooves between the cylinder covers and the connecting table bases; connecting rods sequentially pass through the connecting table bases and the cylinder covers; the connecting rods are used for fixing the cylinder covers, the cylinder body and the connecting table bases through fasteners; the piston assembly comprises a piston and the like; piston sealing rings are positioned in grooves in the two ends of the piston; the two ends of each piston sealing ring are separately fixed through a piston outer baffle late and a piston inner baffle plate; piston wear-resisting rings are positioned in grooves of the piston; magnetic rings are firmly buckled in grooves of the piston; adapter rings cling to inner holes of the pist
