7、然不同。EDUR多相流泵设计成在泵进口侧导入空气进行运行，而不会产生气蚀，这是普通离心泵无可匹及的。这样做，可以使得气-液充分混合并使液体中的气体饱和度达到最佳。在泵的常规运行状态下，液体中的气体含量高达30%时泵仍可以正常稳定的运行。EDUR多相流泵还具有少量杂质进入时耐磨损性好，泵的运行工况点变化时性能特性曲线稳定等优点。随着气体含量在液体内的增加，泵的流量和压力以及输入功率也会随之下降。EDUR多相流泵出色的效能和简单便捷的安装，使得它在短时间内取代了常规的，低效率的多相设备。德国市政废水处理厂采用EDUR多相流泵每年能节省能源开支高达20万欧元。Contents347101112182
