The Centrifugal Pump with the Impeller Supported in Sealing Clearances

The paper presents the construction of single-staged centrifugal pump with the impeller supported in longitudinal and transversal sealing clearances. In the state of equilibrium the impeller is supported by axial and radial forces and moments of pressure, which occur on both sides of the impeller in annular clearances. In the result the impeller adopts optimal non-contact position in which all the external forces that works on this are in balance. A description of the statics and the dynamics of the impeller has been presented.
