    • This invention relates to a pump system, especially for boosting the flow rate of a fluid through a pipe (1, 2, 6), comprising a pump positioned in a pump chamber (10) for pumping at a chosen rate, and a motor driving said pump, the motor being positioned in a chamber (9) being provided with a pressurized fluid, the pressure of which being higher than the pressure in the pump chamber, the motor and the pump chambers being separated by a seal (8), the seal allowing a leakage of said pressurized fluid between them, wherein the pressurized fluid is acceptable to the pump environment and the system comprises a discharge branch line (3) coupled to the pipe(6) and positioned downstream from said pump, the discharge branch line having an outlet into the environment.
    • 本发明涉及一种泵系统,特别是用于提高通过管道(1,2,6)的流体的流速,该管道包括位于泵室(10)中的泵,用于以选定的速率泵送,以及电动机驱动 所述泵,所述马达定位在腔室(9)中,所述腔室(9)设置有加压流体,所述加压流体的压力高于泵室中的压力,所述马达和所述泵室由密封件(8)分开,所述泵 允许所述加压流体在它们之间泄漏的加压流体,其中所述加压流体对泵环境是可接受的,并且所述系统包括联接到所述管道(6)并且位于所述泵下游的排放分支管线(3),所述排放分支管线 有进入环境的出口。
