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.

An oscillating centrifugal pump, comprising: (a) a housing with a longitudinal axis, having a front end and a rear end, spaced apart on said axis, said housing including a pumping chamber within and at the front end of said housing, said pumping chamber being defined by a continuous transverse front
An oscillating centrifugal pump, comprising: (a) a housing with a longitudinal axis, having a front end and a rear end, spaced apart on said axis, said housing including a pumping chamber within and at the front end of said housing, said pumping chamber being defined by a continuous transverse front wall to close said pumping chamber at said front end of the housing, a transverse rear wall with a central opening, axially-spaced from said transverse front wall, and a longitudinal closed side wall, between said front and rear transverse walls, said housing being closed except for an inlet in said housing, outside of, and axially spaced from said pumping chamber, and an outlet in the longitudinal side wall of said pumping chamber, said housing being free of mechanical bearings, flexing or rubbing external seals, or apertures leading to the exterior of the housing except for said inlet and outlet, (b) an impeller in said pumping chamber, said impeller having an axial inlet and a radial outlet and a flow passage between said impeller inlet and outlet, said impeller being mounted on an elastic support, which provides limited freedom of angular oscillation for said impeller about the longitudinal axis of said housing, said elastic support being a torsion member within said housing with a front, oscillating, end connected to said impeller, and a rear, stationary, end connected to said housing, said impeller also containing a magnetic element, and (c) magnetic means external to said housing including an external magnetic element to interact with said magnetic element contained in said impeller and to drive said impeller in an angular oscillation about the longitudinal axis within said pumping chamber by magnetic action through the walls of said pumping chamber.
