一、DOS型单级双吸离心泵概述：
DOS型单级双吸离心泵是我公司引进国外先进技术研制开发的高效产品，具有立卧两用的特点，该泵广泛适用于自来水厂、空调循环用水、灌溉、排水泵站、电站、市政工程供水系统、消防系统、船舶工业，还可用于炼油工业、民用建筑给排水，暖通制冷、冶金、化工制药等领域。与原S、SA、SH型双吸离心泵相比，优势突出，是理想的替代产品。
二、DOS型单级双吸离心泵概述特点：
1、结构紧凑 直线型设计，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，且有优异水利性能的叶型，并经精密铸造，泵壳内表面及叶轮及其光滑具有显著的抗气蚀性能和高效率。
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BURGMANN硬质合金机械密封,能保证8000小时运行无泄漏。
5、安装形势 装配时不需调整，可根据现场使用条件。
