isgd型低转速离心泵
       isgd型低转速离心泵系在isg型基础上并参照is型离心泵之性能参数，根据管道式离心泵的独特结构组合设计制造。该产品采用国内水泵专家提供的最先进水力模型，高效节能，性能可靠，深受国内外客商的赞益。
isgd型低转速离心泵产品特点：　　isgd型低转速离心泵是在isg型立式离心泵基础上配用低转速电机，大幅度降低了运行噪音，成倍延长易损件命名用寿命，低转速离心泵最适用于空调循环及采暖循环和各种循环系统末端增压。创新设计的立式结构使其占地面积和占用空间更少，使用更方便。
isgd型低转速离心泵主要用途：　　isgd型低转速离心泵：主要用于空调系统冷冻水，冷却水循环及末端增压，城市供热系统局部或末端增压循环，及城市建筑消防系统局部恒压及各种空调热水锅炉配套。
isgd型低转速离心泵工作条件：　　isgd型电机0.75kw以上泵系统最高工作压力为1.6mpa即泵吸入口压力+泵扬程≤1.6mpa，泵静压试验压力为2.5mpa，0.75kw以下泵系统最高工作压力为0.8mpa。　　　　订货时请注明系统工作压力，泵系统工作压力大于1.6mpa时，应在订货时另行提出，以便在制造时泵的过流部分和联接部分采用铸钢材料。　　　　isgd制泵介质为冷热水或物理化学性质类似于水的液体，介质温度不超过120℃。
