Centrifugal pump with suction and pressure connections on same axis

摘要

A suction channel extends from the suction connection (2) via a deflection area to the suction mouth (5) of the running wheel. The suction channel in the deflection area has a conical section (6), which runs in a narrowing manner to the suction mouth of the running wheel. The part (9) of the suction channel running vertically to the running wheel axis (4) issues somewhat radially in the conical section. At least a wall part remains with part-conical inner shape. To the conical section of the suction channel a cylindrical channel section (7) connets which is arranged directly before the suction mouth.
