ZWL型直聯式自吸無堵塞排污泵是在反復研究國內外同類技術的基礎上開發成功的一種結構新穎的產品。該泵集自吸和無堵塞排污于一體，采用軸向回流外混式，并通過泵體、葉輪流道的*設計，即可象一般自吸清水泵那樣不需要安裝底閥和灌引水，又可吸排含有大顆粒固體和長纖維雜質液體，可廣泛適用于市政排污工程、河塘養殖、輕工、造紙、紡織、食品、化工、電業、纖維、漿料和混合懸浮等化工介質的雜質泵。 ZWL自吸泵采用直聯式結構與國內同類產品相比，具有結構簡單緊湊、振動少，自吸性能好、排污能力強、高效節能，使用維修方便等特點，在排污泵系列產品中屬國內*。各項技術性能指標居國內，達到*水平，具有廣闊的應用市場和發展前景。

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.
