Abstract

1458693 Centrifugal pumps ATELIERS DE CONSTRUCTIONS ELECTRIQUES DE CHARLEROI 8 March 1974 [9 March 1973] 10479/74 Heading F1C A centrifugal pump vertically mounted in a casing 2 below intake and discharge pipes 3, 4, comprises two convergent inlets 7, 8 each containing a respective screw inducer 9, 10. The latter prevent the dispersion of gas bubbles occluded in the pumped fluid.
