Abstract In order to obtain development trends of multistage centrifugal pump, the technology in multistage centrifugal pumps was studied from the point of view of patent data, including patent application trend, patent distribution in various countries, IPC distribution, patentee distribution and patent citation frequency. At the same time, based on patent map technology, a few major research directions in multistage centrifugal pump technology were identified. It is shown that studies on multistage centrifugal pump technology are relatively little, mainly conducted in China, and in the developing stage, suggesting the multistage centrifugal pump technology is still a hot spot in research. Enterprises and individuals usually are patentees of multistage centrifugal pump technology abroad, but institutes and universities are the patentees in China, furthermore, these patents are not all commercialized. Themes of multistage centrifugal pump technology in patents are mainly focused on design of the pump parts, while those on its application are less. The core technology or basic study on multistage centrifugal pump is basically distributed in the United States, and the most frequently cited patent on multistage centrifugal pump is US7407371B2.
