Abstract

Настоящее изобретение относится к рабочему колесу насоса центробежного или полуаксиального типа, предназначенного для перекачки различных жидкостей, в основном сточных вод. Согласно настоящему изобретению рабочее колесо насоса содержит ступицу (4), снабженную одной или несколькими лопастями (5), входящие кромки (6) которых сильно скошены назад. Периферия (8) входящей кромки смещена на 125-195 градусов относительно соединения (7) этой кромки со ступицей (4).
