Rexroth A20VO60 axial piston variable hydraulic pump

Unlike standard single-piston pumps, the A20VO60 utilizes a dual axial piston rotary group arranged in a swashplate design . This "double pump" configuration allows it to serve two separate hydraulic circuits simultaneously from a single housing. Imagine an excavator: the A20VO60 can drive the track propulsion on one side and the boom articulation on the other without complex valving.

Specifically designed for open circuit hydrostatic drives, this pump thrives in environments where the fluid returns to a non-pressurized tank . This makes it ideal for applications requiring rapid cycling and high flow rates without the parasitic losses associated with closed-loop systems.

Decoding the Model Code

For procurement specialists and maintenance engineers, the model code is critical. Take the common variant AA20VO60DFR1/10R-VSD24K68 .

DFR1: This denotes a specific pressure and flow control system. It allows the pump to automatically "de-stroke" (reduce flow) once a preset system pressure is reached, maintaining constant pressure while only delivering the flow required by the actuator .

10R: Refers to the series index and rotation direction (clockwise).

VSD24K68: Specifies the through-drive and shaft details (SAE spline).

Understanding these codes ensures you receive the exact control logic your system requires.

Practical Applications in the Field

The A20VO60 is engineered for durability under extreme duress.

Mobile Machinery: In compact excavators and wheel loaders, the variable displacement feature allows for smooth, slow-speed maneuvering while holding a heavy bucket, then instantly switching to high-speed travel .

Industrial Presses: For injection molding machines, the pump provides rapid traverse at low pressure, then shifts to slow, high-pressure clamping without overheating the oil .

Through-Drive Flexibility: A standout feature is the through-drive capability. You can mount a secondary gear pump or another axial piston pump directly onto the back of the A20VO60, creating a multi-pump system without needing an additional PTO (Power Take-Off) .

Q1: What is the difference between the A20VO and the A20VLO?

A1: The "L" in A20VLO denotes a larger bearing and shaft extension on the through-drive. If you plan to mount a heavy secondary pump, opt for the A20VLO version for increased mechanical durability .

Q2:The pump is running hot. Where do I start?

A2:Check the power control setting. If the DFR1 control is misadjusted, the pump may fail to de-stroke properly, causing continuous full flow over the relief valve, which generates massive heat. Verify the pressure cut-off setting matches the system specification .
