三、安装方便：泵进出口法兰与标准阀门法兰相同，且位于同一中心线上，中心低，便于管道布置，泵房设计也更为合理实用。
3. Easy installation: The flange of pump inlet and outlet is the same as the flange of standard valve, and is located on the same central line. The center is low, which is convenient for pipeline arrangement, and the design of pump room is more reasonable and practical.
四、绝对的便拆功能、检修方便、维护费少：
4. Absolute disassembly function, convenient maintenance and low maintenance cost:
1、AYSLB型泵采用密封便拆式结构，该泵在检修机械密封件时，不需拆卸电机与进出口管路，只需拆开并取下对夹式连轴器，然后再拆开并取出泵盖上的密封件压盖，即可取出机械密封进行更换，检修十分方便省力。
1. AYSLB pump adopts a sealed and disassembled structure. When repairing mechanical seals, the pump does not need to disassemble the motor and the inlet and outlet pipeline. It only needs to disassemble and remove the clamp coupling, and then disassemble and take out the seal cover on the pump cover, so that the mechanical seal can be removed and replaced. The maintenance is very convenient and labor-saving.
五、平稳、使用寿命长：SLB型泵采用特制的对夹式连轴器，具有运行平稳，噪音低，组件同心度高，增加了运行的平稳性，使用寿命长。
5. Stable and long service life: SLB pump uses special pair-clamp coupling, which has smooth operation, low noise, high concentricity of components, and increases the stability of operation and long service life.
六、使用效率高、性能好：叶轮采用新型双吸式结构水力模型设计制造，消除了原立式泵径向拉力大的不足之处，运行中叶轮始终处于悬浮状态，具有效率高，性能好等特点。同时也降低了石墨轴承的平面磨损，从而提高了水泵的使用寿命，降低了运行成本。
6. High efficiency and good performance: The impeller is designed and manufactured with a new double-suction hydraulic model, which eliminates the deficiency of large radial pull force of the original vertical pump. The impeller is always in suspension state during operation, and has the characteristics of high efficiency and good performance. At the same time, it also reduces the plane wear of graphite bearing, thus improving the service life of the pump and reducing the operation cost
