<p>A single body A-B is provided forming the centrifugal pump spiral having in its lower part a hydraulic collector A which is expanding in the upper part, back to the spiral, in a coaxial air-separator filter wet well B. Said hydraulic collector A is formed by water input channelling with inlets (1a and 4a) with only one connection way and inlets (2a and 3a) to be reversible. The water from the different inlets coming in the collector A, goes to canalized to the wet well B in upper position with its inside space longitudinally divided by an air separator-filter (1b) and transversally by a separator element (2b). The mixture water/air inside the wet well B is divided such the water for induced intake from the centrifugal impeller C, crosses the filter (1b), arrives in the spiral through the conduit (3b) and goes out from the inlet/outlet conduit (4b) while the air comes to flow in the upper part (5b) with bigger volume to then goes out from the thermal relief (6b). <IMAGE></p> |
