ISG/IHG循環水用泵是為便于系統用水循環利用而配備的生產用泵，泵型根據使用條件可選擇ISG或ISW型，即立式或臥式。根據介質的腐蝕性及含雜質情況，可選擇鑄鐵或不銹鋼材質，以提高耐用度。因這類用泵使用情況較復雜，可在確定泵型前向濟南源匯泵業業務人員咨詢。

概述

ISG、IRG、GRG、IHG、YG、TEB系列單能單吸立式管道離心泵，采用IS型泵性能參數、水力模型。機泵一體，進出口徑相同且位于同一水平線上，軸封采用機械密封。TEB是我廠根據用戶維修泵時由于空間和起吊設備的限制，裝拆極不方便而研制的產品。
　　1、ISG型管道泵適用于供暖及空調系統冷熱水循環、高層建筑給水、消防管路增壓、遠距離輸水、工業生產工藝循環增壓、園林噴灌、介質為清水或物理、化學性質類似于清水的其它介質。介質溫度不超過80℃。
　　2、IRG型熱水管道離心泵主要用于暖房、鍋爐、浴室冷熱水循環，各行業的無腐蝕性熱水增壓循環。介質溫度不超過150℃。
　　3、GRG型高溫管道離心泵主要用于鍋爐給排水循環、冷熱水循環、采暖等行業輸送無腐蝕性高溫液體。介質溫度不超過200℃。
　　4、IHG型化工管道離心泵主要用于化工、環保、儀器釀造、制藥、造紙、輕紡等行業增壓、輸送化學腐蝕性液體。介質溫度不超過100℃
　　5、YG型管道油泵用于輸送不含固體顆粒，粘度小于120厘沱的無腐蝕性油類和石油產品。輸送介質溫度為-20～80℃。
　　6、TEB為便拆式立式管道泵，改變材質即可適用于以上各種工作環境。
