LIQUID CIRCULATION PUMP USING MAGNETIC FORCE

A liquid circulation pump using magnetic force is provided to manufacture a magnet holder and an impeller easily by molding the magnet holder integrally with a magnet, and a permanent magnet integrally with the impeller. A liquid circulation pump using magnetic force includes a motor bracket(110), a pump bracket(140), a blocking housing(150), a magnet holder(120), and an impeller(130). The motor bracket is fixed at a motor(100) and penetrated by a motor shaft. The pump bracket has an inlet for introducing liquid from the outside, and an outlet for discharging the liquid. The blocking housing prevents the liquid introduced into the pump bracket from entering the motor bracket, and has a cylindrical receiving unit. The magnet holder has magnets along the circumferential direction, and rotates with the shaft of the motor. The impeller comprises a cylinder(131) and a plurality of blades formed as one body with the cylinder.
