The sealing member 13 correspondingly covers the pump housing 10, when the pump structure is conventionally known. When the first operation is started, the axial center of the rotor group 11 will continuously rub against the pump casing 10 to cause mechanical loss, thereby reducing the service life of the pump structure 1, and further, the shaft center and the pump casing. The friction of the body 10 is easy to cause noise problems. In addition, the pump housing 10 also has a large axial space requirement due to the space required for the shaft base 102 and the rotor assembly 11.
