ZW series self-priming sewage pumps are with self priming and sewage discharge. Imeanshe pumps canooly be self priming ashe same as ZX series self priming pump for cleawater withoufoovalve and pouring water bualso suck and dischargehe large graiand long fiber and sedimenand impurity ithe waste water. Andhe performance is very steady. Iis very covenieo operate and move and install and maiain. ①Enviromeemperature≤45℃，Liquidsemperature≤120℃。 ②Liquid PH: Casiropump :6～9，Stainless steel :1～14。 ③Max graidiameter cabe 60% of caliber for pump. Length of fiber cabe 5imes as caliber for pump. ④Impurity weighio liquid canomoreha15% of liquid weight. Liquid density≤1240kg/cm3 自吸排污泵集自吸和无堵塞排污于一身，既可象一般清水自吸泵那样不需按底阀，不需引灌水、又可抽吸含有大颗粒固体块、长纤维的污物、沉淀物废矿杂质、粪便处理及一切工程污水物，完全减轻工人的劳动强度，而且使用、移动、安装方便、极少维修、性能稳定。 ①环境温度≤45℃，介质温度≤120℃。 ②介质PH值铸铁泵为6～9，不锈钢泵为1～14。 ③通过颗粒*直径为泵口径的60%，纤维长度为口径的5倍。 ④介质中杂质总重量不超过介质总重量的15%，介质比重不超过1240千克/立方米。 材质： 过流部件材质：铸铁、不锈钢。
