1. efficient high pressure-bearing horizontal multi-stage centrifugal pump;

  • Comprise water exit end (1), inlet segment (7), impeller (3), water outlet support stator (4), stator (5), fluid director (6), pump shaft (8), motor shaft (14);

    It is characterized in that;

    multistage centrifugal pump is through inlet segment (7) and water exit end (1) radially sucks, axially water outlet;

    Stator (4) and the outer withstand voltage tube (2) that is provided with of stator (5) are supported in water outlet;

    Water exit end (1) and inlet segment (7) pass through pull bar (10) thereby withstand voltage tube (2), water outlet support stator (4), stator (5), fluid director (6) are fixed in tension;

    Pump shaft (8) one ends pass with motor shaft (14) from inlet segment (7) cavity center and are connected, and an end is connected with impeller (3), and inlet segment (7) is provided with mechanical seal (9) with pump shaft (8) cooperation place.
