Abstract
The invention is to attain high speed rotation while minimizing abrasion between a bearing and a shaft. A pump comprises: an impeller 1 in which a lot of blades 2 are disposed to an outer circumference of a cylinder part 1a and a rotor magnet 3 is disposed to an inner circumference of the cylinder part 1a; a motor stator 4 disposed on an inner circumferential side of the rotor magnet 3 to rotary drive the impeller 1; a partition plate 6 partitions between the impeller 1 and the motor stator 4 to be air-tight; a pump casing 5 having a suction port 9 sucking liquid and a discharge port 10 discharging liquid. A dynamic pressure generating groove 12 for generating dynamic pressure by the rotation of the impeller is disposed to at least one of an outer circumferential face 1A of the cylinder part 1a of the impeller 1 and a cylindrical face 6A of the partition plate 6 facing the outer circumferential face 1A.
