摘要： A multistage centrifugal pump in which each stage includes a one-piece or multi-piece housing and an impeller disposed therein. The pump stages are arranged between an inlet end member and an outlet end member and retained therebetween by connectors so as to be connected to a flow-guiding system. All impellers are positioned on a single pump shaft that is supported by at least two pump bearings. One end of the pump shaft is provided with a device for receiving a connector of a drive unit, and outer support members are disposed at mounting points adjacent the end members in order to mount the centrifugal pump in its installation location. The pump shaft (3) is supported by two two pump bearings (11, 12), with the maximum distance (LL) between confronting sides of the two pump bearings (11, 12) being less than or equal to a minimum structural stage height (LM) multiplied by the number of pump stages (2.1-2.5) minus 1.
摘要翻译：一种多级离心泵，其中每级包括一体式或多件式的壳体和设置在其中的叶轮。泵级设置在入口端构件和出口端构件之间，并通过连接器保持在其间，以便连接到流动引导系统。所有叶轮都位于由至少两个泵轴承支撑的单个泵轴上。泵轴的一端设置有用于接收驱动单元的连接器的装置，并且外部支撑构件设置在邻近端部构件的安装点处，以将离心泵安装在其安装位置。泵轴（3）由两个两个泵轴承（11,12）支撑，两个泵轴承（11,12）的相对侧之间的最大距离（L L L L）小于或等于最小结构级高度（L M M）乘以泵级数（2.1 - 2.5）减1。
