MULTI-STAGE, SELF-PRIMING CENTRIFUGAL PUMP ASSEMBLY |
| 摘要 |
A multi-stage, self-priming centrifugal pump assembly includes at least two pump stages (4) which are consecutive in a main flow direction (32), and a backflow channel (13) which lies parallel to at least one a pump stage (4). The backflow channel (13) runs out downstream of the first or a further pump stage (4), in the main flow direction (32). |

1. A multi-stage, self-priming centrifugal pump assembly comprising:
at least two pump stages which are consecutive in the a main flow direction and which include a diffuser; and a backflow channel which lies parallel to at least one a pump stage and which runs out downstream of the first or a further pump stage (4-) in the main flow direction, wherein the backflow channel runs out downstream of the diffuser of the at least one pump stage. |
