Abstract: As typical hydraulic machines, pumps play an important role in the national economy, and progress in pump technology attracts concerns from many industries. Driven by various application requirements on the modern pump, significant advances have been achieved in its theory and technology along with the rapid development in the related disciplines such as materials science, mechanics, informatics, and computer science. At present, its internal flow mechanisms and operating characteristics are understood more deeply, information technology is widely used in its design, operation and maintenance, and new pump products are gradually becoming eco-friendly and intelligent. This article focuses on the progress in the technology of various vane pumps achieved over the last two decades, including vortex pumps, centrifugal pumps, mixed flow pumps, axial flow pumps, and tubular pumps. Based on the requirements of product applications, this paper summarize the developing trends in the hydrodynamics, design technology, vibration and noise, and operation and maintenance technology of the modern pumps.

Key words: pumps, hydrodynamics, design technology, vibration and noise, operation and maintenance technology
