A head of suction pipe of a pump includes suction pipeline to the lower end of which a funnel, as a truncated cone broadened downwards, is rigidly connected. On the side surface of the funnel, at the side of the larger basis, triangular cuts are arranged, and plate-splitters are provided, those are rigidly fixed, for instance with welding, at outside of the side surface by generatrix of the truncated cone of the funnel with respect to the tops of triangular cuts. |
