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水力模型，节能，性能，深受国内外客商的赞益。
低转速离心泵产品特点：
ISGD型低转速立式离心泵是在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，zui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。 低转速离心泵主要用途：
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。 低转速离心泵工作条件：
ISGD型电机0.75kw以上泵系统zui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zui高工作压力为0.8MPa。
低转速离心泵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低转速离心泵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。 低转速离心泵性能参数: 型号流量Q扬程（M） 效率（%） 转速（r/min）电机功率 （KW）必需汽蚀 余量 （NPSH）r重量（kg）（m3/h）（L/S）40-1003.20.8934814000.122.51740-1253.20.8954014000.182.51940-125A2.80.7843914000.122.51940-1603.20.8983614000.252.52440-160A2.80.786.43514000.182.52240-2003.20.8912.53114500.552.53840-200A2.80.78103014000.372.53040-2503.20.89202514501.12.55240-250A2.80.78162514500.752.54740-250B2.30.64132414500.552.54640-100（I）6.31.7535414000.122.51740-125（I）6.31.755.05414000.252.52940-125（I）A5.61.564.05214000.182.52440-160（I）6.31.758.04714500.552.54340-160（I）A5.11.425.34514000.252.53040-200（I）6.31.7512.54014500.752.54540-200（I）A5.51.539.53914500.552.54440-250（I）6.31.75203214501.52.55440-250（I）A5.61.56163214501.12.54940-250（I）B5.11.42133014500.752.54250-1006.31.7535414000.122.51950-1256.31.755.05414000.252.52550-125A5.61.564.05214000.182.51950-1606.31.758.04714500.552.54250-160A5.11.425.34514000.252.53750-2006.31.7512.54014500.752.54850-200A5.51.539.53914500.552.54650-2506.31.75203214501.52.55850-250A5.61.56163214501.12.55050-250B5.11.42133014500.752.54950-100（I）12.53.4736314000.252.52350-125（I）12.53.475.06314000.372.53450-125（I）A11.03.063.86014000.252.53350-160（I）12.53.4785914500.552.846110型号流量Q扬程（M） 效率（%） 转速（r/min）电机功率 （KW）必需汽蚀 余量 （NPSH）r重量（kg）（m3/h）（L/S）50-160（I）A10.83.065714000.372.83450-200（I）12.53.4712.55414501.12.85250-200（I）A11.33.1410.15314500.752.84850-250（I）12.53.47204514502.22.87350-250（I）A11.73.2517.64414501.52.86550-250（I）B10.22.8313.44314501.12.86050-315（I）12.53.47323614504.02.88950-315（I）A11.73.25283614503.02.88450-315（I）B10.22.81213414503.02.88265-10012.53.4736314000.252.82965-12512.53.475.06314000.372.83265-125A11.03.063.86014000.252.82765-16012.53.4785914500.552.84665-160A10.83.065714000.372.83565-20012.53.4712.55414501.12.85265-200A11.33.1410.15314500.752.84865-25012.53.47204514502.22.87665-250A11.73.2517.64414501.52.86865-250B10.22.8313.44314501.12.86365-31512.53.47323614504.02.88965-315A11.73.25283614503.02.88565-315B10.12.81213414503.02.88265-100（I）256.9437014000.372.83365-125（I）256.9457014500.752.84965-125（I）A21.86.053.86514500.552.84865-160（I）256.9486814501.12.85465-160（I）A21.66.06.06514500.752.84865-200（I）256.9412.56414502.22.87165-200（I）A23.36.4710.96314501.52.86265-250（I）256.94205914503.02.88565-250（I）A22.26.1715.85814502.22.88065-250（I）B19.85.512.65714501.52.87465-315（I）256.94325014505.52.812065-315（I）A236.3927.95014504.02.8110110型号流量Q扬程（M） 效率（%） 转速（r/min）电机功率 （KW）必需汽蚀 余量 （NPSH）r重量（kg）（m3/h）（L/S）65-315（I）B20.25.61214914503.02.810080-100256.9437014500.372.83380-12521.86.9457014500.752.84880-125A256.053.86514500.552.84580-16021.66.9486814501.12.85580-160A256.06.06514500.752.85180-20023.36.9412.56414502.22.87280-200A256.4710.96314501.52.86480-25022.26.94205914503.02.88980-250A19.86.1715.85814502.22.88580-250B255.512.65714501.52.87880-315236.94325014505.52.813080-315A20.26.3927.95014504.02.810280-315B505.61214914003.02.89580-100（I）5013.8937314500.753.05880-125（I）44.613.8957314501.13.06180-125（I）A5012.446314501.13.06180-160（I）44.513.8987314502.23.08280-160（I）A5012.366.37114501.53.07480-200（I）44.613.8912.57214503.03.09780-200（I）A5012.369.97114502.23.09380-250（I）44.513.89206614505.53.013480-250（I）A5012.9717.46514504.03.010680-250（I）B44.611.2213.16314503.03.010080-315（I）5013.893261145011.03.018080-315（I）A46.712.9727.96114507.53.016680-315（I）B40.511.22216014505.53.062100-1005013.8937314500.753.070100-1255013.8957314501.13.068100-125A44.612.446314501.13.068100-1605013.8987314502.23.087100-160A44.512.366.37114501.53.079100-2005013.8912.57214503.03.0100100-200A44.612.369.97114502.23.090110型号流量Q扬程（M） 效率（%） 转速（r/min）电机功率 （KW）必需汽蚀 余量 （NPSH）r重量（kg）（m3/h）（L/S）100-2505013.89206614505.53.0140100-250A46.712.9717.46514504.03.011213.16314503.03.0105100-3155013.893261145011.03.0225100-315A46.712.9727.96114507.53.0180100-315B40.511.22216014505.53.0165100-125（I）10027.7857814502.23.095100-125（I）A87.124.23.87614501.53.087100-160（I）10027.7887814504.03.0118100-160（I）A87.124.26.37614503.03.0113100-200（I）10027.7812.57514505.53.0148100-200（I）A86.123.929.37314504.03.0123100-250（I）10022.782074145011.03.0208100-250（I）A93.325.9217.47314007.53.0165100-250（I）B8724.17157214505.53.0149100-315（I）10022.783271145015.03.0234100-315（I）A91.025.282771145011.03.0213100-315（I）B79.021.94207014507.53.0165100-400（I）10022.785065145030.03.0375100-400（I）A9426.114465145022.03.0295100-400（I）B8724.173864145018.53.0257100-400（I）C8122.5632.862145015.03.0239125-1258022.257614502.23.0148125-125A71.519.947514501.53.0125125-1608022.287414503.03.0205125-160A69.319.367314502.23.0165125-2008023.212.57314505.53.0249125-200A7520.8117214504.03.0237125-2508022.2207214507.52.8220125-250A7520.817.57114507.52.8210125-250B6911.2157014505.52.8195125-3158022.23267145015.02.5300125-315A7520.827.566145011.02.5282125-315B72202565145011.02.5245 |
