Abstract (en)
[origin: US6280156B1] A magnetically coupled rotary pump has, in a pump chamber, a pump rotor mounted by a single slide bearing on a stationary axis of a pump bearing support. The slide bearing is formed on one side by a metal sleeve shrunk over the bearing sleeve, said sleeve being connected by means of a weld with the pump rotor, and on the other side by a bushing mounted on the pump bearing support or a one-piece slide bearing surface formed correspondingly directly on pump bearing support. With this design of the bearing, dead spaces and gaps are avoided, enabling complete cleaning and sterilization of the pump chamber with complete draining of the pump chamber. A pump of this kind is especially suitable for use in sterile applications.
