A non-chokable pump, comprising:
- a pump housing;
- and
- an impeller arranged in the pump housing, the impeller having vanes configured to deliver solids-containing media,
- wherein
- at least in a portion of the vanes, at least one vane section branches off from an origin vane section of each of the portion of the vanes,
- the vanes are open in a direction facing toward an opposing wall of the pump housing that contains an inlet of the non-chokable pump,
- an open space exists between axial upper ends of the vanes and the opposing wall of the pump housing, the open space and a circumferential gap between at least a portion of the vanes are sized such that solids in the solids-containing media which are passable axially through the inlet of the non-chokable pump are passable radially through the impeller.
