ZWL型直联式自吸无堵塞排污泵是在反复研究国内外同类技术的基础上开发成功的一种结构新颖的产品。该泵集自吸和无堵塞排污于一体，采用轴向回流外混式，并通过泵体、叶轮流道的*设计，即可象一般自吸清水泵那样不需要安装底阀和灌引水，又可吸排含有大颗粒固体和长纤维杂质液体，可广泛适用于市政排污工程、河塘养殖、轻工、造纸、纺织、食品、化工、电业、纤维、浆料和混合悬浮等化工介质的杂质泵。 ZWL自吸泵采用直联式结构与国内同类产品相比，具有结构简单紧凑、振动少，自吸性能好、排污能力强、高效节能，使用维修方便等特点，在排污泵系列产品中属国内*。各项技术性能指标居国内，达到*水平，具有广阔的应用市场和发展前景。

ZWL Direct-coupled self-priming pump

ZWL type direct-coupled self-priming sewage pump is no blockage in repeated studies abroad on the basis of similar technology developed a novel structure of the product. The self-priming pump sets and non-clogging sewage in one, outside the axial back mixing style, and through the pump body, impeller's unique design, can be as general as self-priming pumps do not need to install the foot valve and irrigation water, suction with large particles can be solid and liquid impurities long fiber can be widely applied to municipal sewage works, Hetang farming, light industry, papermaking, textile, food, chemical, electrical, fiber, chemical pulp and mixed media such as suspension ideal impurity pump. The pump Direct-coupled structure and similar products, compared with a simple structure, less vibration, better performance, self-priming, sewage capacity, energy efficient, easy maintenance, etc., in the sewage pump products in a national initiative. The technical performance lead at home to reach the international advanced level, with broad applications and prospects.
