进口不堵塞液下泵是美国尼科NICO在传统耐腐蚀液下泵基础上,经改进设计而生产的新型泵;该泵取消了其他液下泵普遍采用的机械密封和选用了独特结构的叶轮,使泵高效节能、无泄漏、寿命特长，从而广泛应用于石油、化工、制药、造纸、冶金、污水处理等行业。进口不堵塞液下泵采用独特的单叶片或双叶片叶轮结构，大大提高了污物通过能力，能有效的通过泵口径的 5倍 纤维物质与直径为泵口径约50%的固体颗粒。进口不堵塞液下泵机械密封采用新型硬质耐腐的碳化钨材料，同时将密封改进为双端面密封，使其长期处于油室内运行，可使泵安全连续运行 8000小时以上。进口不堵塞液下泵整体结构紧凑、体积小、噪声小、节能效果显著，检修方便，无需建泵房，潜入水中即可工作，大大减少工程造价。进口不堵塞液下泵密封油室内设置有高精度抗干扰漏水检测传感器，及定子绕组内预埋了热敏元件，对水泵电机绝对保护。进口不堵塞液下泵可根据用户需要配备全自动安全保护控制柜，对泵的漏水、漏电、过载及超温等进行绝对保护，提高了产品的安全性与可靠性。 浮球开关可以根据所需液变化，自动控制泵的起动与停止，不需专人看管，使用极为方便。进口不堵塞液下泵可根据用户需要配备双导轨自动耦合安装系统，它给安装、维修带来极大方便，人可不必为此而进入污水坑。进口不堵塞液下泵能够在全扬程范围内使用，而保证电机不会过载。 有两种不同的安装方式，固定式自动耦合安装系统，移动式自由安装系统。

1、泵为立式液下泵，外形美观，直接安装在被输送介质的储存器上，无额外占地面积，从而降低了基建投入。
2、取消了机械密封，解决了其他液下泵因机械密封容易磨损而须经常维修的烦恼，节约了泵的运行成本，提高了工作效率。
3、采用了独特的记心式双平衡叶轮，供输送了不含固体颗粒等清洁的介质，振动噪音特低，效率高；采用开式双平衡叶轮，供输送不清洁带有固体颗粒及短纤维的液体，运行平稳、不堵塞。
