Abstract

538,658. Centrifugal pumps. REICH, L., WELLISCH, S., and SOMLO, Z. Feb. 14, 1940, No. 2828. [Class 110 (i)] A centrifugal pump a is submerged with its shaft d vertical, and is driven by a flexible shaft n and gearing o, t, u, p operated by hand or motor. The pump comprises two impellers f, fll in series, the lower one drawing through a strainer b and delivering through peripheral ports h in a sheet metal plate g<1>, and then through a central eye in an upper sheet metal plate g to the upper impeller, which delivers to the pipe c. The ends of the impeller blades are bent out at f1 to guide the liquid. The casing a may be made of stamped sheet metal. The impellers are carried by a head e fixed to the shaft d.
