ISWD型低转速离心泵在ISW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。ISWD型低转速离心泵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。离心泵的制造和研究已有几百年的历史。1754年，瑞士数学家L.欧拉导出叶轮式水力机械的基本方程，奠定了离心泵设计的理论基础。但到19世纪50年代为止，离心泵的生产和技术并未获得重大进展。低转速离心工作条件ISWD型离心泵电机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，离心泵静压试验压力为2.5MPa，0.75kw以下泵系统最高工作压力为0.8MPa。低转速离心产品特点ISWD型低转速离心泵是在ISW型卧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，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。ISWD型低转速离心泵性能参数离心泵型号流量Q扬程(m)效率(%)转速(r/min)电机功率(kw)必需气蚀余属(NPSH)r重量(kg)(m3/h)(1/s)40-1002.23.24.20.610.891.473.332.84814000.122.51740-1252.23.24.20.610.891.475.554.54014000.182.51940-125A2.02.83.70.560.781.034.443.63914000.122.51940-1602.23.24.20.610.891.178.587.53614000.252.52440-160A2.02.83.70.560.781.036.86.463514000.182.52240-2002.23.24.20.610.891.471312.5123114500.552.53840-200A2.02.83.70.560.781.0310.4109.63014000.372.53040-2502.23.24.20.610.891.1720.52018.52514501.12.55240-250A2.02.83.70.560.781.0316.416152514500.752.54740-250B1.62.33.40.440.640.9413.213122414500.552.54640-100(I)3.86.37.51.061.752.083.432.85414000.122.51740-125(I)3.86.37.51.061.752.085.45.04.65414000.252.52940-125(I)A3.45.66.70.941.561.864.343.75214000.182.52440-160(I)3.86.37.51.061.752.088.58.07.54714500.552.54340-160(I)A3.05.16.10.831.421.695.65.34.94514000.252.53040-200(I)3.86.37.51.061.752.0813.112.5124014500.752.54540-200(I)A3.35.56.50.921.531.81109.593914500.552.54440-250(I)3.86.37.51.061.752.0820.52019.53214501.52.55440-250(I)A3.45.66.70.941.561.8616.41615.63214501.12.54940-250(I)B3.15.16.10.861.421.6913.21312.53014500.752.54250-1003.86.37.51.061.752.083.432.85414000.122.51950-1253.86.37.51.061.752.085.45.04.65414000.252.52550-125A3.45.66.70.941.561.864.34.03.75214000.182.51950-1603.86.37.51.061.752.088.587.54714500.552.54250-160A3.05.16.10.831.421.695.65.34.94514000.252.53750-2003.86.37.51.061.752.0813.112.5124014500.752.54850-200A3.35.56.50.921.531.81109.593914000.552.54650-2503.86.37.51.061.752.0820.52019.53214501.52.55850-250A3.45.66.70.941.561.8616.41615.63214501.12.55050-250B3.15.16.10.861.421.6913.21312.53014500.752.54950-100(I)7.512.5152.083.474.173.532.56314000.252.52350-125(I)7.512.5152.083.474.175.45.04.763140010.372.53450-125(I)A6.611.013.21.833.063.674.13.83.66014000.252.53350-1607.512.5152.083.474.178.887.25914500.552.846离心泵型号流量Q扬程(m)效率(%)转速(r/min)电机功率(kw)必需气蚀余属(NPSH)r重量(kg)(m3/h)(1/s)50-160(I)A6.510.813.01.813.03.616.665.45714000.372.83450-200(I)7.512.5152.083.474.1713.212.511.85414501.12.85250-200(I)A6.811.313.51.893.143.7510.710.19.65314500.752.84850-250(I)7.512.5152.083.474.17212019.44514502.22.87350-250(I)A7.011.714.11.943.253.9218.417.6174414501.52.86550-250(I)B6.110.212.11.692.813.9214.113.413.04314501.12.86050-315(I)7.512.5152.083.474.1732.33231.73614504.02.88950-315(I)A711.7141.943.253.9228.12827.63614503.02.88450-315(I)B6.110.212.11.692.813.9221.22120.83414503.02.88265-1007.512.5152.083.474.173.532.56314000.252.82965-1257.512.5152.083.474.175.45.04.76314000.372.83265-125A6.611.013.21.833.063.674.13.83.66014000.252.82765-1607.512.5152.083.474.178.887.25914000.552.84665-160A6.510.813.01.813.03.616.665.45714500.372.83565-2007.512.5152.083.474.1713.212.511.85414001.12.85265-200A6.811.313.51.893.143.7510.710.19.65314500.752.84865-2507.512.5152.083.474.17212019.44514502.22.87665-250A7.011.714.11.943.253.9218.417.6174414501.52.86865-250B6.110.212.11.692.813.9214.113.413.04314501.12.86365-3157.512.5152.083.474.1732.33231.73614504.02.88965-315A711.7141.943.253.9228.12827.63614503.02.88565-315B6.110.212.11.692.813.9221.22120.83414503.02.88265-100(I)1525304.176.948.333.532.57014500.752.83365-125(I)1525304.176.948.335.654.57014000.552.84965-125(I)A13.121.826.13.056.057.254.33.83.46514500.372.84865-160(I)1525304.176.948.33987.26814501.12.85465-160(I)A13.021.625.93.616.07.196.76.05.46514500.752.84865-200(I)1525304.176.948.3313.212.511.86414502.22.87165-200(I)A14.023.327.93.896.477.7511.510.910.26314501.52.86265-250(I)1525304.176.948.33212018.859145032.88565-250(I)A13.322.226.63.696.177.3916.615.814.85814502.22.88065-250(I)B11.919.823.83.315.56.6113.212.611.85714501.52.87465-315(I)1525304.176.948.3332.53231.55014505.52.812065-315(I)A1423283.896.477.7528.327.927.45014504.02.8110)
