S/SH系列单级双吸中开泵(离心泵) ，供输送清水或物理化学性质类似于水的其它液体之用。被输送液体温度不得高于80℃。适用于工厂、厂矿、城市给水、电站、农田排灌和各种水利工程。
一、单级双吸中开泵(离心泵) 性能范围
泵进口直径DN: 100∽1400mm
流量Q: 最高1800m3/h
扬程H: 最高135m
工作压力P: 最高2.5MPa
工作温度T: 最高135°C
二、单级双吸中开泵(离心泵) 结构说明
S/SH系列单级双吸中开泵(离心泵) 为单级、双吸、泵壳轴向中开的蜗壳式离心泵。泵吸入口与吐出口均在泵轴心线下方，呈水平方向。
泵主要零件有泵体、泵盖、叶轮、轴、双吸密封环等。
泵进出水法兰上，设有安装真空表和压力表的管螺孔，进出水法兰底部设有放水管螺孔。法兰按GB标准制作，也可采用ISO、DIN、BS或ANSI标准制作.
叶轮经平衡校验合格后，用轴套及轴套螺母固定在轴上，其轴向位置可通过轴套螺母进行调整。叶轮轴向力利用其叶片对称布置达到平衡。泵轴由两套滚动轴承支撑，安装在泵体两端。轴承采用油脂润滑。
泵体上设有双吸密封环，拆卸更换方便。
泵通过弹性柱销联轴器或金属迭片式联轴器由电动机直接传动。驱动机也可采用内燃机、气轮机。
轴封可采用填料密封，也可采用机械密封。轴封冷却冲洗水可通过泵盖中开面上的凹槽进入轴封腔，也可通过外接冷却水管进入轴封腔。
S/SH系列单级双吸离心泵(中开泵)检修时勿需拆卸进出水管及电动机，维修方便。
根据用户需要，可改变泵结构尺寸。
