The cylindrical rotor is loosely supported through a corrosion-resistant ball bearing,
The cylindrical rotor is magnetized in a striped manner along the axial direction on its outer circumferential surface, and has spiral blades on its inner circumferential surface. There is no need to apply a lubricant such as grease, and as a result, an excellent effect is achieved in that there is no influence on the components of the liquid to be transferred. Furthermore, since the fluid is allowed to flow through the center of the cylindrical rotor, wall resistance is reduced, and the fluid flows efficiently. By forming the cylindrical bulge, the cylindrical rotor, and the ball bearing that supports the rotor from corrosion-resistant materials, rust prevention is achieved, durability is increased, and the selection range of the counter-dye liquid to be transported is greatly expanded. It will spread to Furthermore, since the structure of the rotor is cylindrical and point symmetric, there is an advantage that the direction of fluid transfer can be reversed by 1iT. Furthermore, the target liquid itself serves as a lubricant between the field and the rotor.
