结构特点
与WFB型自吸泵相比，WLZ（WZY）型自吸泵具有明显技术优势：
1、水泵叶轮为闭式结构，效率较WFB泵叶轮采用的开式结构高10％～15％，同性能参数泵所配电机功率普遍低一个档次，节能显著，同时，叶轮汽蚀性能好，安装允许吸深较WFB泵深0.5～1m。
2、水泵自吸采用“多通道叶片式气水混合分离器（自吸盘）”，具有快速完成自吸过程的突出特点，较WFB型泵采用单蜗壳式压水室自吸时间缩短1/3～1/2以上，而且泵体积小，重量轻。
3、进水型式有两种：WLZ型泵采用管道式结构，进、出口可在平面360°任何方位吸入排出。WZY型泵采用下吸式，排出口可在平面270°任何方向。检修水泵时，均无需拆卸进、出口管道，特别是WZY型占地面积小，节省基建投资。
4、密封采用多面连环流体动力密封，由副叶轮密封和停机密封组成，WFB型流体动力密封未设专用停机密封，不适用于频繁启动场合。
5、联接方式为水泵和电机刚性直联。从电机端俯视，泵为顺时针方向旋转。
6、水泵进口无需像WFB泵那样带止回阀或电磁真空破坏阀等辅助设备，本身具有自动破坏虹吸的U型管特殊结构和空气平衡孔，停机时，虹吸作用不能抽空泵内储液，因此，只要首次运行时注满液体，以后运行无需加液，真正实现一次注液，终身受用。
7、水泵可配备控制柜，它具有根据液体自动启停和过载报警等多种功能，实现无人操作，自动工作。

Type WLZ、WZY Vertical Non-Leakage Self-suction Pump
General
Type WLZ、WZY pump which designed and developed by our factory is our country’s pioneering product (Patent No. 200320114083.4). It is widely used in the fields of petroleum, chemical, metallurgy, power station, steel, mine, paper-making, electrodeposit, environmental protection, fire-extinguishing, architecture and sewage-treating. Part of them can instead of inundated pump, long-shaft pump or pump started frequently. It is suitable for delivering clear water, seawater, sewage with little particles (no fibre), industrial waste water, oil and other medium with corrosion.

Construction feature
Type WLZ (WZY) self-suction pump has more advantages than type WFB self-suction pump. The feature is as following:
1. The impeller is closed structure with excellent performance. Its efficiency is 10%～15% higher and permissible installing suction depth is 0.5～1m deeper than that of type WFB pump with opened impeller. Compared with other pumps with the same performance parameter, the motor power of this kind pump can be more low, so it saves more energy.
2. Pump adopts air-water mixed vane segregator with many passages (self-suction disc) for suction, the suction speed is more fast and its self-suction time is 1/3～1/2 shorter than that of type WFB pump with single volute pressure water chamber. The pump has small cubage and light weight.
3. There are two types for water entering：Type WLZ pump adopts pipe-structure with inlet and outlet installed at any angle of plane 360°. Type WZY pump’s suction mouth is downward and outlet can be installed at any angle of plane 270°.It has the features of space-saving and less cost for construction. It needn’t dismantle inlet and outlet pipes while maintenance.
4. Seal uses dynamical sealing which includes vice-impeller sealing and breakdown sealing. But type WFB pump has no special breakdown sealing and it is not suitable for start-up frequently.
5. Connection: Pump is connected with motor through rigid coupling. View from motor end , the rotating direction of pump is clockwise.
6.It is unnecessary to fix check valve or electromagnetism vacuum-destroy valve in pump inlet, it has U pipe which can automatically break siphon and air-balance hole, when pump stops operating, siphon can not pump all water out of pump , so only when pump first starts, it should be poured liquid.
7. Pump Can be equipped with controller which can automatically start and stop pump according to liquid level, and give an alarm for over loading, pump can work automatically without any help of people.
