The research and development process of CY piston pump can be traced back to the late 1960s, which was independently designed and manufactured by China. In the 1970s to the late 1990s, CY pumps were mainly used in industrial machinery industries such as forging and metallurgy, ending the situation of no piston pump options for forging machinery in China and laying the foundation for the design and manufacturing of domestic hydraulic piston pumps. ‌

 

In the research and development process, the successful development of CY pump marks a major breakthrough in China's hydraulic technology. Although it may not be as widely used as before, it reflects the technological level and innovation capability of China's hydraulic industry in the past.

 

In addition, the development history of Rexroth axial piston pumps (motors) also provides background information. Its prototype can be traced back to the early 16th century, and after improvement and development by multiple countries and engineers, axial piston pumps gradually became one of the most widely used hydraulic components in modern hydraulic transmission.
