Abstract

181,525. Simms, W. H., (Pfalz Akt.-Ges.). April 1, 1921. Multi-stage centrifugal pumps; casings.-In multi-stage pumps and compressors with low radial discharge velocity components, the guideblades b serving to guide the liquid from one stage to the next are in an axial direction in the maximum diameter of the flow-channel and adjacent the wall of the pump.
