,Einleitung. Historische Übersicht,unted on an extension of the driver shaft. Couplings are either rigid or flexible. The choice is determined by the bearing arrangement of the pump and driver combination. Rigid couplings permit neither radial nor axial relative motion between the driving and driven shafts, effectively making them a

A demand naturally developed, therefore, for a centrifugal pump able to handle appreciable quantities of air and to reprime itself automatically when located above the water supply. This requirement is especially important in the co

,Leistungsfähigkeit und Leerlauf,ction of its vanes on the liquid and is the only component of a centrifugal pump that does so. The other components, even those that convert kinetic energy to pressure, absorb some energy from the liquid. Given its unique function, the impeller can be considered the fundamental component of a centrifugal pump.
