性能及优点
S型中开泵的吸入口和吐出口均在水泵的轴心线下方，与轴线垂直成水平方向。维修方便，无须拆卸进、出水管路及电动机，高效节能、应用范围广。
S型单级双吸水平中开式离心泵是新型节能卧式中开泵，主要由泵体、泵盖、轴、叶轮、密封环、轴套、轴承部件等组成，其吸入口和排出口均在水泵轴心线下方，检修时，只要将泵盖揭开，即可将全部零件拆下进行维修。供输送清水或物理化学性质类似水的其它液体，根据用户需求，通过改变泵结构及材质可用于输送多泥沙水或各类腐蚀性液体。其性能符合JB/1050-93《单吸双吸清水离心泵型式与基本参数》标准。
应用范围
S型中开泵适用于工厂、矿山、城市给水、电站、自来水、农田灌溉和各种水利工程。
