ISGD低转速立式离心泵概述：
ISGD立式低转速管道离心泵系在ISG系列基础上并符合国际标准的性能参数，根据管道式离心泵的独特结构组合设计而成，并严格按照国际标准ISO2858进行设计制造。
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，部分产品出口国外，深受国内外客商的赞誉。
ISGD低转速立式离心泵用途：
ISGD型低转速立式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低转速立式离心泵特点：
ISGD型立式低转速离心泵是在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，成倍延长易损件使用寿命，最适用于空调循环及采暖循环和各种循环系统末端增压。管道泵创新设计的立体式结构使其占地面积和占用空间更少，使用更方便。
ISGD低转速立式离心泵工作条件：
低转速离心泵所用的电机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，以便在制造时离心泵的过流部分和联接部分采用铸钢材料。
低转速离心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℃。
ISGD低转速立式离心泵型号意义：
ISGD低转速立式离心泵结构图及结构说明：
1、泵与电机同端盖，轴向尺寸缩短，结构简单；
2、泵体上设有取压孔和放水孔；
3、泵体上设有排气阀，工作前能排放泵内空气。
4、泵体底部设有安装底板和螺栓孔，保证整体机组安装稳固。
