    Abstract: The invention concerns a production of precision castings by centrifugal casting, comprising the following steps: a) providing a centrifugal casting device having a rotor (1) being rotatable around an axis (A), and at least one crucible (8) being accommodated in the rotor (1) and at least one mold (4) being associated with said crucible (8) and being accommodated in a first radial distance (r1) from the axis (A), b) creating a metal melt (15) within the crucible (8), c) rotating the rotor (1) and thereby forcing the melt (15) by means of centrifugal forces from the crucible (8) into the mold (4), d) exerting a pressure on the melt (15) being forced into the mold (4) until the temperature of the solidifying melt (15) has reached a predetermined cooling-temperature in a range of 1300° to 800° C., wherein the pressure corresponds to the centrifugal force acting on the melt (15) at the moment when the mold (4) is completely filled times a factor of 1.0 to 5.0, and e) relieving the pressure when the temperature of the solidifying melt (15) is smaller than said predetermined cooling-temperature.

    Abstract: An oscillating centrifugal pump is disclosed which has a housing, an impeller and a magnetic drive. The housing has a longitudinal axis, having a front end and a rear end that are spaced apart on the longitudinal axis. The housing includes a pumping chamber within and at the front end of the housing. The pumping chamber is created by a continuous transverse front wall that closes the pumping chamber at the front end of the housing, a transverse rear wall axially-spaced from said transverse front wall and has a central opening, and a longitudinal closed side wall which is between the front and rear transverse walls. The housing is closed except for an inlet in the housing that is outside of and is axially spaced from the pumping chamber. An outlet is provided in the longitudinal side wall of the pumping chamber, and the housing is free of mechanical bearings, flexing or external seals or apertures that lead to the exterior of the housing except for said inlet and outlet. The impeller is located in the pumping chamber and has an axial inlet and a radial outlet and a flow passage between the impeller inlet and outlet. The impeller is mounted on an elastic support, which provides limited freedom of angular oscillation for the impeller about the longitudinal axis of the housing.
