pump

Abstract

The pump (1) comprises: a magnetic drive unit that generates a magnetic field; a rotating body (20); and a separating wall (410). The rotating body (20) comprises: a magnetic driven unit that rotates about an axis by means of the magnetic field generated in the magnetic drive unit; and an impeller (70) integrally disposed on the magnetic driven unit. The separating wall (410) divides the space (510) accommodating the rotating body (20) and the magnetic drive unit. A flow path (F1) for fluid flow is formed between the separating wall (410) and the magnetic driven unit in the space (510). An inflow suppression part (200) is formed in at least one of the impeller (70) and the separating wall (410), the inflow suppression part (200) suppressing the inflow of fluid into the flow path (F1) and reducing the flow rate of the fluid flowing in the flow path (F1).
