概述：
ZL系列立式自吸泵是在反复研究国内外自吸泵技术的基础上开发成功的一种结构新颖的产品，采用导叶式气水分离装置，一次引流，终生自吸，填补了国内外立式自吸泵的空白。
该泵具有结构紧凑，外表美观，自吸性能好，高效节能，占地面积小，运行平稳，进出口径相同并在同一水平线上，可以安装于任一段水平，可以安装于任一段水平管路上，使用维修方便等特点，具有广阔的应用市场和发展前景，因该泵具有自吸功能，因此完全可代替ISG系列立式管道离心泵的使用。
使用范围：
ZL型立式自吸泵、ZLH型立式自吸化工泵、ZLB型立式自吸油泵，可广泛适用于工业和城市给排水，高层建筑增压送水，电子，电力，化工，冶金，医药，食品，电镀，环保，消防，净水，国防，军工，纺织印染，油田，油库，加油站，采掘选矿等行业输送各咱介质。
环境温度≤40℃，相对湿度<95%，介质温度≤70℃，系统压力≤1.6MPa。泵静止试验压强力2.5MPa，介质中固体颗粒含量不超过单位体积的0.1%，粒度>0.2mm。
