G型离心式管道泵
G型离心式管道泵（简称：G型管道泵）又称G型单级单吸立式离心泵，其额定性能点符合ISO2858国际标准，采用新国家行业标准JB/T6878.1-93，管道式离心泵型与基本参数JB/T6878.2-93管道式离心泵技术条件，其效率平均上升了3-5%，是取代原SG型管道泵的节能型新产品，最高工作压力不大于1.0MPa，吸入口压力不大于0.2MPa。
本系列泵的节能范围(设计点)流量3.2-400m3/h，扬程10-80米，根据所输送介质对泵腐蚀情况，用户可选用适应接角液体部分的材质，泵与介质接触的主要零件材质如下表所示：
除下表所列材质外，允许用户选用其他所需适合本系列泵生产的材质，材料及其代号原则应符合GB2100-80标准的规定。对国家没有规定代号的材质可采用国际通用的材料代号或国内公认的材料代号(如行业或本企业的规定)。
