Pump head of magnetic force submerged pump

The invention discloses a pump head of a magnetic force submerged pump, belonging to the technical field of submerged pumps. The pump head of the magnetic force submerged pump comprises a pump body (1), a pump body wearing-ring (2), an impeller nut (3), an impeller (4), a pump cover (5), a double-end stud (46), a nut (47) and a screw (50). The invention solves the problems of long drive shaft, large vibration and noises, poor product stability and safety, short service life and zero-impurity requirement for medium of the traditional submerged pump, and provides the submerged pump with the advantages of stable operation, use safety, no leakage of medium, long service life, low requirement for medium, and no limits on the depth of a storage tank.
