ISG/IHG65-250循环水用泵

ISG/IHG循环水用泵是为便于系统用水循环利用而配备的生产用泵，泵型根据使用条件可选择ISG或ISW型，即立式或卧式。根据介质的腐蚀性及含杂质情况，可选择铸铁或不锈钢材质，以提高耐用度。因这类用泵使用情况较复杂，可在确定泵型前向济南源汇泵业业务人员咨询。

概述

ISG、IRG、GRG、IHG、YG、TEB系列单能单吸立式管道离心泵，采用IS型泵性能参数、水力模型。机泵一体，进出口径相同且位于同一水平线上，轴封采用机械密封。TEB是我厂根据用户维修泵时由于空间和起吊设备的限制，装拆极不方便而研制的产品。
　　1、ISG型管道泵适用于供暖及空调系统冷热水循环、高层建筑给水、消防管路增压、远距离输水、工业生产工艺循环增压、园林喷灌、介质为清水或物理、化学性质类似于清水的其它介质。介质温度不超过80℃。
　　2、IRG型热水管道离心泵主要用于暖房、锅炉、浴室冷热水循环，各行业的无腐蚀性热水增压循环。介质温度不超过150℃。
　　3、GRG型高温管道离心泵主要用于锅炉给排水循环、冷热水循环、采暖等行业输送无腐蚀性高温液体。介质温度不超过200℃。
　　4、IHG型化工管道离心泵主要用于化工、环保、仪器酿造、制药、造纸、轻纺等行业增压、输送化学腐蚀性液体。介质温度不超过100℃
　　5、YG型管道油泵用于输送不含固体颗粒，粘度小于120厘沱的无腐蚀性油类和石油产品。输送介质温度为-20～80℃。
　　6、TEB为便拆式立式管道泵，改变材质即可适用于以上各种工作环境。
