Abstract
719,441. Centrifugal pumps. SULZER FRERES SOC. ANON. Nov. 28, 1952 [Nov. 29, 1951; Feb. 23, 1952], No. 30253/52. Class 110(1) In a pumping plant comprising a main pump of the high speed centrifugal type fed through a pipe by a feeder pump submerged in the liquid, the pumping chamber of the main pump lies below the level of a body of liquid connected with the pipe. The feeder pump 6 is of the axial-flow type and delivers water through pipe 4 and pipes 5 to a double-flow multi-stage centrifugal pump 3. A compensating chamber 18, which may be an open tank as shown or may be a closed tank in which a pressure cushion of gas or air is maintained above the water level 19, is connected by pipe 17 to the pipe 4 downstream of a non-return valve 21. Automatic means may be provided for stopping the pump 3 if the water level 19 falls below a permissible limit. In a modification, the electric driving motor 15 of the pump 6 is replaced by a water turbine which is supplied with water from tappings between stages of the pump 3. The chamber 18 and non-return valve 21 are omitted and the pump 3 is situated below the level of the water 1.
