产品概述
OS泵为单级双吸中开式离心泵。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，符合标准GB5657.
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最低限度，且有优异水力性能的叶轮，并经精密铸造，泵壳内表面及叶轮表面极其光滑，具有显著的抗汽蚀性能和高效率。
3.轴承选用国产优质轴承或SKF及NSK轴承，保证运行平稳，噪音低，使用寿命长。
4.轴封选用国产优质机械密封或BURGMANN机械密封或填料密封。机械密封能保证8000小时运行无泄漏。
5.安装装配时不需调整，可根据现场使用条件。分立式或卧式安装。
