Impeller periphery
WitrynaThe impeller is the piece that rotates inside the casing to effect pumping (Fig. 23.5). The input of the pump is at the eye and the liquid enters perpendicular to the plane of the … WitrynaThe single volute design imposes a radial force on the impeller due to variations of pressure around the impeller periphery above and below best efficiency point flow. In cases where this radial force results in excessive shaft deflection, a double volute design (Figure B) is used.
