Abstract The new process of catalyst cracker, which deals with crude petroleum with more sulphur and larger density, requires a new catalyst pump to remain high efficiency. However its severe abrasion, erosion of the main parts that fluid flow through and coking action on its surface make the useful life shortened. A new type of pump aiming at solving the problems R&D. The peculiarity in structure, design method, the makeup and application of special metal material and some information about its use in Jiujiang River petrochemical oil-refine factory are introduced. The comparison of its running performance with former pump 250py-100 is also given.
