G型管道式離心泵(簡稱:G型管道泵)又稱G型單級單吸立式離心泵,其額定性能點符合ISO2858國際標準,采用好新國家行業標準JB/T6878.1-93,管道式離心泵型與基本參數JB/T6878.2-93管道式離心泵技術條件,其效率平均上升了3-5%,是取代原SG型管道泵的節能型新產品,好高工作壓力不大于1.0MPa,吸入口壓力不大于0.2MPa。
本系列泵的節能范圍(設計點)流量3.2-400m3/h,揚程10-80米,根據所輸送介質對泵腐蝕情況,用戶可選用適應接角液體部分的材質,泵與介質接觸的主要零件材質如下表所示:
除下表所列材質外,允許用戶選用其他所需適合本系列泵生產的材質,材料及其代號原則應符合GB2100-80標準的規定。對國家沒有規定代號的材質可采用國際通用的材料代號或國內公認的材料代號(如行業或本企業的規定)。
