Abstract (en)
[origin: EP1918591A2] The pump (1) has an impeller (4) formed to be axial or semi-axial, and an inlet nozzle (5) arranged in a flow direction (SR) of the pump before the impeller. Another inlet nozzle (6) is arranged concentric to the nozzle (5), where the two nozzles are arranged one behind the other in the flow direction such that an annular gap (11) is formed between the nozzles. The gap is arranged directly in front of an impeller intake (12) in the flow direction. An inlet channel (13) formed from one of the nozzles is connected with a fluid volume (14) that is partially surrounded by the nozzles.
