概述
我们的MSN/MSND泵广泛用于炼油厂，石化，石油生产和管道应用，例如锅炉饲料，多产品运输，水喷射，瘦肉和半叶流程等重型服务。他们与各种驱动器一起工作，包括蒸汽和燃气轮机的电动机；而且，我们甚至设计了泵送火车，可应要求与燃气发动机一起使用。
The multi-stage design is double-volute type to balance radial rotor loads at all capacities—thus optimizing unit reliability. The horizontally split case is designed to withstand the highest working and hydrostatic pressures typical for water-injection services. Suction and discharge nozzles are integrally cast with the lower half of the case to permit disassembly of the pump and rotor removal without disturbing the piping connections. Two-row rotors with opposed impellers provide axial balance over the entire operating range.
该泵可以配备可选的第一阶段叶轮，其眼部较大，可用于单次吸力，在大多数情况下，双抽吸可获得低NPSH要求。每个叶轮都被键入轴，并组装收缩。
All MSN/MSND pumps are full-load tested on dedicated rigs in our factory; complete train test can be performed on demand to validate the entire scope of supply.
