Why Choose a Rexroth A2FO Hydraulic Pump?
The Rexroth A2FO fixed displacement axial piston pump is designed for open-circuit hydraulic systems where stable hydraulic flow, dependable pressure capability and mechanical robustness are important. Unlike variable displacement pumps, the A2FO delivers a fixed geometric displacement per revolution, making it a practical solution for hydraulic circuits with predictable flow requirements.
Its bent-axis axial piston architecture provides efficient mechanical power transmission and makes the A2FO suitable for demanding mobile and industrial hydraulic applications. Bosch Rexroth documentation identifies the A2FO as a fixed-displacement, open-circuit, high-pressure axial piston pump family. :contentReference[oaicite:1]{index=1}

A2FO Operating Principle
The A2FO converts mechanical shaft rotation into hydraulic flow through an axial piston and bent-axis mechanism. As the drive shaft rotates, the piston assembly performs a reciprocating movement that draws hydraulic fluid into the pump and delivers pressurized fluid to the hydraulic circuit.
Because the A2FO uses a fixed displacement design, the theoretical flow is primarily determined by pump displacement and rotational speed. This makes the pump particularly useful when the hydraulic system requires a predictable flow source rather than continuous electronic displacement adjustment.

How to Select the Correct A2FO Pump?
Overseas buyers should confirm the complete Rexroth model code rather than selecting the pump only by displacement.
2. Operating pressure and peak pressure
3. Required rotational speed
4. Rotation direction
5. Shaft and mounting configuration
6. Port connection requirements
7. Hydraulic fluid and operating temperature
8. Original replacement or complete new unit requirement
A2FO pumps with similar displacement may differ in shaft, mounting, ports, rotation, seal configuration or series. Providing the complete nameplate information helps suppliers identify the correct hydraulic pump faster.
