Abstract

1391743 Centrifugal pumps VORTEXPUMPEN AG 12 Sept 1973 [13 Sept 1972] 42798/73 Heading F1C A centrifugal pump comprises an inlet socket 3 provided with a spherical shut-off valve 6 and an outlet socket 10 provided with a non-return valve 11. The valves allow the pump to be isolated from the pipeline for the purpose of dismantling the pump for cleaning. A nut 1 can be unscrewed for removal of the driving motor and pump impeller 5.
