Abstract
Изобретение касается центробежного насоса для откачки жидкостей с загрязнениями, главным образом в виде твердых частиц, причем насос содержит узел привода, гидравлический узел, а гидравлический узел содержит корпус насоса (20) и рабочее колесо насоса (12), настроенное для вращения внутри корпуса, рабочее колесо насоса содержит верхний (14) и нижний (16) закрывающий диск и определенное количество промежуточных лопаток (18). Изобретение характеризуется тем, что на нижней стенке (22) корпуса насоса, которая имеет центральное впускное отверстие (24), установлено, по крайней мере, одно средство воздействия на обратный поток выноса (32, 34), на стороне, обратной к нижнему закрывающему диску, который проходит вокруг впускного отверстия часть оборота или целый оборот.
