S型单级双吸离心泵供抽送温度低于80℃的清水或物理化学类似于水的其它液体之用。S系列单级双吸清水泵主要适用于自来水厂、空调循环用水、建筑供水、灌溉、排水泵站、电站、工业供水系统、消防系统、船舶工业等输送液体的场合。
S型单级双吸离心泵的作条件：
流量范围：0.8m3/h~120 m3/h；
扬程范围：5.6m~330m；
温度范围：-20℃~120℃；
输送液体种类：各种清洁水及轻腐蚀液体；
泵腔承压：≤4.0MPa。
S型单级双吸离心泵的结构特点：
1、 结构紧凑 外形美观，稳定性好，便于安装。
2、 运行平稳 优化设计的双吸叶轮使轴向力减小到低限度，且有优异水力性能的叶型，泵壳内表面及叶轮表面具有抗汽蚀性能。
3、 轴承选用SKF及NSK轴承保证运行平稳，噪音低，使用寿命长。
4、轴封选用机械密封或填料密封。能保证8000小时运行无泄漏。
5、安装形式 装配时不需调整，可根据现场使用条件。分立式或卧式安装。
6、 加装自吸装置，可实现自动吸水，即不需安装底阀，不需真空泵，不需倒灌，泵可以启动。
