The  AA10VO28ED72/31L-VSC12N00P axial piston variable pump, identified by the part number  R902561612, is a high-performance hydraulic component belonging to the renowned  A10VO Series 31. Engineered for precision, durability, and efficiency, this pump is a core solution for industrial and mobile hydraulic systems that demand stable pressure output and flexible flow control.

As a flagship model in the  A10V/A10VO product line, the  A10VO28 variant (including the AA10VO28ED72 iteration) is designed with a compact footprint, making it ideal for applications with limited installation space while delivering robust power. The pump adopts an axial piston structure, which ensures smooth operation, low noise, and high volumetric efficiency – even under continuous high-pressure working conditions.

The  ED72 control module and  31L-VSC12N00P configuration are key to its variable displacement capability. Operators can easily adjust the pump’s output flow according to real-time system demands, effectively reducing energy consumption and optimizing the overall performance of the hydraulic circuit. This feature makes the pump suitable for a wide range of heavy-duty scenarios, such as construction machinery (excavators, loaders), agricultural equipment, industrial presses, and material handling systems.

In terms of reliability, the AA10VO28ED72/31L-VSC12N00P pump is built with high-quality materials and undergoes strict quality testing. Its robust design resists wear, corrosion, and extreme temperature fluctuations, ensuring a long service life and minimizing maintenance costs. Additionally, it maintains excellent compatibility with standard hydraulic fluids, simplifying integration into existing hydraulic systems.

Whether you need a direct replacement for aging R902561612 pumps or a high-efficiency upgrade for your hydraulic setup, the A10VO Series 31 AA10VO28ED72 axial piston variable pump stands out as a dependable, high-value choice that balances power, precision, and cost-effectiveness.
