Hydraulic systems play a critical role in various industries, providing the power needed for machinery and equipment to perform effectively. Among the various types of hydraulic pumps, the double vane hydraulic pump has seen significant advancements over the years. 

Double vane hydraulic pumps are positive displacement pumps characterized by their use of two sets of vanes to move hydraulic fluid. Unlike single vane pumps, which use a single set of vanes, double vane pumps feature two sets that work in tandem to deliver a more consistent flow of hydraulic fluid. This design offers several advantages, including improved efficiency and smoother operation.

The concept of the vane pump dates back to the early 20th century, when hydraulic systems began to gain traction in various industrial applications. Early double vane pumps were designed with basic components and materials, focusing on simple operation and reliability. These early models set the stage for future innovations by establishing the fundamental principles of vane pump technology.
